Guest Post- SAMSUNG 32? LCD TV LA 32R91B IS REPAIRED

Thu, 02 May 2013 10:55:45 GMT

All the functions of this lcd tv were good except the contrast and brightness controls. When I decreased the contrast and brightness to 50 %, after few minutes it automatically shot up again to 100%. My first suspect was the corrupted program file of EEPROM IC . Since I do not have the original programs I tried to check on the voltages to see if the voltages stable or not.

I measured the output voltages from the power supply and found two voltages were good (13v and 12 v). But the 5 volt line seems to be unstable and fluctuated. After that I saw an electrolytic capacitor that was bulged located along the 5 volt line.

The cap value was 2200 micro farad @ 10 volt 105 C and when tested with my capacitance meter it showed only 32 micro farad. The capacitance value was way out. I checked the same capacitor again with my ESR meter and it showed 2 ESR ohm. By right it should have about 0.02 ESR ohm. After a new replacement was done the control functions of the contrast and brightness of the TV was back to normal again.

JVC Xiview LT-32WX50 review

Mon, 29 Apr 2013 10:51:21 GMT

JVC's Xiview LT-32WX50 knows how to get your attention. Take its price, for instance: at a cool £2,500, it's phenomenally expensive for a 32 inch LCD TV. No surprise, then, that JVC is looking to shift it through custom install channels rather than normal high-street outlets. Also striking is the 32WX50's finish: a rather fetching deep grey aluminium with an optional industrial-style table-top mount and detachable speaker bar. Comfortably, the 32WX50's most stand-out feature, though, is its truly stunning slimness. At its thinnest point it's just 6.4mm deep. That makes it a whole 3 and a bit mm – count 'em! – thinner than last year's Sony 40EX1 groundbreaker. Even the bottom third only 'balloons' to 25mm – still markedly slimmer than Samsung's iconic B8000 LED series.

The screen's slimness aids its custom installation ambitions too. For a screen this thin could be much more easily incorporated than a standard LCD TV into wall, ceiling and shelf AV systems, or fitted using, say, picture frames, railings, interior suspension units, or mirrored chests. Whether the 32WX50's incredible slimness is enough to justify the screen's mammoth price depends on how design-obsessed/well heeled you are. But I suspect that for most people, the 32WX50 will need to do more – so let's find out what features the slender chassis holds.

No tuner
Connections wise, the only findings are two HDMI inputs, a PC RGB input, RS-232 control support, and USB/SD multimedia options. There's no tuner input, because there's no tuner in the screen! It's merely a monitor – which is, of course, entirely acceptable in custom installation circles.

The 32WX50's pictures are driven by JVC's latest picture processing platform, the New DynaPix HD engine. This includes a 12bit Real Bit Driver that enables upconversion of lower bitrate signals such as 8bit HD broadcasts and DVD signals to 12bit Deep Colour signals, resulting in smoother colour gradation. Also part of the new DynaPix HD engine is a Chromaticity Point Conversion Circuit, designed to compensate for colour bleed and colour drift caused by gaps between the source colour format and the LCD's own colour space.

DynaPix HD now incorporates Intelligent Clear Noise Reduction processing, too, which detects and reacts to picture noise in each of a picture's 16 frequency areas, as well as Intelligent Colour Management, which uses a newly-developed algorithm to emulate how people are drawn more to the colours of key objects than they are the colours of surrounding objects. Next up is a new generation (version III) of JVC's Clear Motion Drive technology, delivering enhanced 100/120Hz processing as well as real-time, motion-estimated noise-reduction.

Another interesting ability of the 32WX50 is wide colour gamut coverage. The screen can tackle a full 100 per cent of the sRGB colour spectrum, and around 90 per cent of the Adobe RGB spectrum. This should let it reproduce digital photographs with unprecedented (in the TV world) colour accuracy. There's even a Photo Pro picture preset, designed for D-SLR stills.

Other presets include Game, Theatre, Dynamic, Standard, Monitor and even separate HD and standard-def CCTV options, plus digital signage and medical display settings for commercial applications.

As well as the aforementioned picture presets, you get six separate memory slots for storing your own settings. And among the vast quantity of things you can change are such niceties as the BY gain and BY/ RY angle of the hue setting; separate detail, horizontal and vertical sharpness adjustments; extensive backlight adjustment; colour matrix, temperature and space adjustments; white balance fine-tuning using 'Drive' and 'Cutoff' values for the red, green and blue colour elements; and comprehensive colour management. This latter tool lets you adjust the colour and hue of the red, green, cyan, and yellow components, as well as the hue and colour of skin.

The problem with combining the 32WX50's exceptional picture flexibility with a £2,500 price is that if the picture quality the screen delivers is less than perfect, it's going to feel disappointing. And sadly, the pictures are less than perfect.

Box of wax
Why? First, the picture isn't as sharp as I'd like, especially when it comes to standard-def viewing. Skin tones look slightly waxy, and there's sometimes quite pronounced motion blur, no matter what settings you use.

My other concern is with the black level response. On paper the quoted 4,000:1 native and 80,000:1 dynamic contrast ratios look okay. But in action, the screen's edge-LED lighting system causes distracting light pooling in each corner.

The 32WX50 also suffers with some grey clouding over dark scenes, hiding subtle shadow detailing.
Frustratingly, its failings stand in stark opposition to some startling strengths. For instance, the sheer range of colours the screen produces is, for my money, unprecedented on a 32in TV. With skin tones in regularly watched Blu-ray sequences I witnessed subtleties of tone in different parts of people's faces that I haven't seen before at the 32in level.

Similarly, subtle blends like auras around planets and stars, or the varied shades of red in a sunset sky, are delivered with extraordinary precision. This is striking with digital stills, where the detail, subtlety and accuracy of the 32WX50's colour rendition is simply exquisite. The exceptional subtlety with colours is also used to render colours with uncannily accurate tones.

Somehow this colour accuracy even extends to dark pictures, aside from the way deep blacks look rather grey. While the 32WX50 might not be the greatest screen at suppressing motion blur, it is very accomplished at keeping a lid on judder, leaving images from all sources looking fluid and smooth – but not unnaturally so. The viewing angle is wider than that of most LCD TVs too.

One last string to its bow is audio. For despite being as slim as the thickest part of the screen's slender form, the provided speaker bar kicks out much more clarity, volume, dynamism and soundstage size than most 32in LCD TV speaker systems. There is much to admire about the 32WX50 – and I'm not just talking about its startling design. JVC has clearly poured its heart into making the 32WX50 a custom installer's dream, with no stone of set-up flexibility left unturned. And when its pictures are good, they're stellar. That said, I'd hoped for almost flawless pictures for £2,500. Yet the 32WX50's backlight consistency and motion blur issues ensure that 'almost flawless' is certainly not where its pictures are at.

Samsung UE46F7000 Smart LED TV Review

Fri, 19 Apr 2013 09:21:57 GMT

After having sampled Samsung’s flagship (well, as far as full HD 1080p models go anyway) F8000 series of LED LCD TVs, we’re naturally keen to find out whether its highly accomplished image quality has filtered down to step-down ranges. In for review today is the Samsung UE46F7000, a 46-inch version of the Korean manufacturer’s Series 7 LED TV which, as the number indicates, sits one rung below the top-end Series 8.

According to the specifications sheet, the F7000 features “Micro Dimming Pro” instead of the “Micro Dimming Ultimate” technology (which attempts to deliver pseudo-local dimming at a video processing level from an edge-lit LED LCD panel) found on the higher-up F8000. The 46F7000′s motion-compensated frame interpolation (MCFI) system is also rated lower, coming in at 800Hz CMR or Clear Motion Rate (the F8000′s is 1000Hz). Another notable omission from Series 7 is the dual 10W woofer that significantly enhanced low-end audio performance on the UE55F8000 we tested last month.
However, here at HDTVTest we prefer to let our calibration charts and benchmark tests do the talking despite what the spec sheets say. If the UE46F7000′s picture performance can match that of the pricier F8000, then it may represent better value for money than the latter for viewers who value image quality above all else.

Note: The specific unit we reviewed was the Samsung UE46F7000STXXU which is the United Kingdom 3-pin-plug model. Although we haven’t carried out our tests on the smaller, 40-inch Samsung UE40F7000 nor the bigger 55-inch UE55F7000, there shouldn’t be any drastic difference in picture quality (except perhaps 3D immersiveness due to different screen sizes) given similar specifications within the F7000 series.

Design
The first thing we noticed upon unboxing the Samsung UE46F7000 is that the truly unique arc stand bundled with the F8000 is gone, replaced instead by a more conventional table-top stand with a rectangular base. Nevertheless, there are still a number of swanky stylistic cues to satisfy owners that this is indeed a premium display.

For starters, the bezel looks impossibly slim from the front, successfully creating the illusion that the screen’s larger than it actually is. Inspected from the top and sides, the bezel extends around 2mm deep, and sports a brushed metallic finish which complements that of the TV stand’s rectangular base. Just like the Series 8 LED, a press-to-pop-up camera is embedded along the top of the television.

In another refreshing design endeavour, a Samsung logo – which can be tastefully lit (or not) – adorns the slanted top of the supplied pedestal stand. Assembly is easy, though swivelling is not possible. Overall build quality feels sufficiently solid befitting a mid-high-end flat-panel HDTV, with no untoward creaks nor cheap plastics.

Connections

Operations
Blasting through the user menu, EPG and the company’s new Smart Hub interface was an absolute cinch: we thoroughly appreciate UE46F7000′s lightning-fast responsiveness (presumably endowed by the onboard quad-core processor) which is a big help if you need to access numerous picture-affecting controls for calibration purposes like we do!

The on-screen menus and Smart TV platform on the 46in F7000 is the same as the ones available on the F8000. Since we’ve provided an indepth explanation of various picture options in our 55F8000 review, we won’t repeat it here – please refer to the relevant section if you haven’t read it, or need a refresher.

Remote Control
Just like the F8000, the Samsung 46F7000 comes with two remote controls. The first is a really luxurious-looking clicker with a central touchpad, subtly raised embedded buttons, and an inbuilt microphone to facilitate voice control for when you’re sitting too far away from the television.

While this smartphone-like remote is opulent and actually intuitively usable once you pair it to the TV, we found ourselves preferring to use the more traditional, budget-style variant for day-to-day use and of course calibrating the UE46F7000.

Calibration
As with almost every Samsung flat-screen TV, [Movie Mode] is the picture preset which yielded an image closest to the Rec. 709 specifications used within the video and broadcast industry for HDTV.

Greyscale
With [Colour Tone] left at its default value of “Warm 2” in [Movie Mode], there’s an excess of red component in the greys, which got progressively worse towards top-end luminance. Fortunately, Samsung provided not only 2-point [White Balance] controls, but also a [10p White Balance] submenu which allowed us to work our magic on the screen to produce as neutral a greyscale as possible.

We first used the 2-point [White Balance] controls to bring greyscale broadly in line with D65, then adjusted the RGB sliders in the [10p White Balance] submenu to finetune each 10% stimulus interval. The result is absolutely wonderful, with delta errors (dEs) of under 2 across the entire visible luminance range.

Eagle-eyed readers may wonder why we did not flatten the RGB balance between 40% and 60% even further. This is because we actually used the [10p White Balance] controls to align gamma at each interval, since the 46″ Samsung F7000 does not offer any separate 10p Gamma controls (unlike Panasonic which does so on its mid-high-end models this year). In any case, a dE of 3 is generally considered to be the perceptible limit of greyscale inaccuracy for the human eye, and the UE46F7000′s measurements were comfortably below that.

Gamma
Out of the box, overall gamma in [Movie Mode] tracked closer to 2.2 – this seems to be the target every TV manufacturer is aiming for – than 2.4 which has been decreed by ITU as the reference electro-optical transfer function (EOTF) for flat-panel HDTVs used for studio mastering in a dark room.

After lowering the [Gamma] value (which affects the picture globally) to “-1“, and then repurposing the aforementioned [10p White Balance] controls as our very own 10-point gamma editor, we eventually got gamma tracking linearly at 2.4. Cross-checking with a greyscale ramp pattern, we saw no evidence of excessive posterization despite these tinkerings – just a neutrally tinted, smooth transition from black to white which is crucial to delivering a realistic yet punchy picture.

Colour
With the advent of colour saturation tracking in CalMAN 5, we’ve tweaked our workflow slightly when it comes to colour calibration. We still give colour luminance/intensity/brightness our top priority, since colour decoding errors (particularly red push) are typically the most noticeable to viewers even without the help of a side-by-side comparison. But instead of focusing solely on 100% saturation points like we were originally constrained to, we now pay more attention to what happens inbetween (namely 25%, 50% and 75% saturation points) with the goal of levelling out the inaccuracies between the different points to achieve the best visual result, as these are more representative of the saturations commonly seen in real-world content.

On our Samsung UE46F7000 review unit, [Colour Space] “Auto” yielded reasonably accurate chromaticities at 100% saturation, but sub-100% saturation tracking points ran relatively hot (i.e. they appeared more saturated than they should be) across all six primary and secondary colours. To rectify this, we dialled down the global [Colour] control, aiming to place the 75%, 50% and 25% saturation points as close as possible to their reference coordinates.

Because the F7000 features such an excellent RGB-based colour management system accessible through [Colour Space] “Custom“, it would be criminal for us not to use it. Although the lack of negative headroom prevented us from adjusting the primary hues as much as we’d like, we achieved essentially flawless colour luminance, and what we would classify as excellent saturation tracking.

LG – “LG Smart TV” – 7 new series of LED LCD TV (17 models)

Sun, 07 Apr 2013 20:01:53 GMT

LG Electronics Japan announced that they will release 7 new series of their “LG Smart TV” – 17 models in all – in chronological sequence starting in late April. The “LG Smart TV” will feature regular TV broadcasts and various smart content, apps, SNS, etc. These new models are the second “LG Smart TV” series.

LG developed them by putting more importance on operability than previous models. Examples of newly added functions are “Voice Search” that researches online by a keyword you say to the microphone built into the remote control, and “Motion Recognition” that recognizes hand movement to control volume or change the channel, etc. (LA9600/LA8600 only). Also, LG had a CPU built-in for the first time to their TVs to make them more fun and user-friendly.

LA9600, LA8600, and LA6600 feature “Miracast” that enables you to connect your smartphone and tablet to the TV wirelessly and to enjoy movies or photos saved in the mobile device on the big screen. Also, the “2nd Display” function makes it possible for you to enjoy live content from the TV on your mobile device.

4Kx2K LCD TV panel shipments expected to reach 2.5M in 2013

Mon, 01 Apr 2013 11:27:39 GMT

TFT LCD panel suppliers are forecast to ship 2.6 million 4K×2K LCD TV panels (also known as Ultra HD) worldwide in 2013, up more than 40-fold from 63 thousand in 2012, according to the latest NPD DisplaySearch Quarterly Large Area TFT Panel Shipment Report.

TFT LCD panel suppliers play a pivotal role in 4K×2K LCD TV adoption, providing innovative cost-effective technology solutions that will meet the anticipated demand for these devices. Specifically, they are focused on leveraging new technologies, such as high-transmittance cell designs, high-output driver integrated circuits (ICs), and high-efficiency backlight units and integrated up-scaling circuits for 4K×2K panels.

“To date, Innolux Corp. has been the most aggressive panel manufacturer in this market segment, developing a full line-up of 4K×2K panels in the 39" to 85" range,” noted David Hsieh, NPD DisplaySearch Vice President, Greater China Market. “Despite this, 4K×2K panel manufacturers’ shipments are primarily focused on 50", 55"/58”, and 65" sizes, which are expected to have the highest volume shipments, especially in China.”

Panel manufacturers are also looking to accelerate 4K×2K panel adoption by strengthening their relationships with LCD TV brands with more aggressive manufacturing and sales efforts. “4K×2K LCD TV is the newest TV technology available, and in order for it to be successful, it will be critical for the supply chain to avoid falling behind when making their purchases, even if content is still scarce,” Hsieh added. “Some panel makers are also working with design houses to develop circuits built into the panel, to enable up-scaling of HD to 4K×2K content. This will help to drive the 4K×2K LCD TV market and encourage panel makers, especially those that have already started design-in work with TV brands in 2013.”

LG 55LA8600 (55-inch LCD)

Sun, 27 Jan 2013 19:07:49 GMT

The LA8600-series TVs are LG's new flagship entries in the full-HD and LED-edgelit segments. Besides some small cosmetic tweaks, the chaebol has also enhanced the onboard connectivity options with both near-field communication (NFC) and Miracast technologies. Other noteworthy extras include a "natural voice recognition" and "On Now" functions to provide a more seamless smart TV user experience. Lastly, this series is available in 47- and 55-inch screen sizes.

Upside:
The LA8600 has all the hallmarks of a high-end model. It features an In-Plane Switching (IPS) panel that can deliver wider viewing angles, as well as smooth 200Hz motion and local dimming for deeper blacks. The latest "magic" stand is stylish and equally functional with a built-in swiveling function. Meanwhile, an ultra-slim bezel, unobtrusive pop-up camera and an illuminated LG logo are other key design highlights.

Sharing content between these LG TVs and mobile devices is a breeze, too, thanks to the integrated Wi-Fi, WiDi, MHL, Miracast and NFC connectivity. The equivalent of Apple AirPlay, Miracast allows users to stream 1080p videos and 5.1-channel surround sound through Wi-Fi. Instead of using a password to pair like Bluetooth, you can hold your smartphone over an NFC sticker on the TV to complete the procedure.

As for natural voice recognition, you can now utilize more conversational verbal commands, such as "show me Gangnam-style video", to operate the smart TV system. This should come in handy for the "On Now" function, which is basically a content recommendation system. This series is likely bundled with the new Magic Remote universal controller, which is also compatible with other 2013 LG home A/V products.

Downside:
According to LG, the inbuilt camera does not support gesture control and is used mainly for Skype when the LA8600 launches. Nevertheless, this is not a serious handicap as motion-sensing is already supported by the Magic Remote. Those who are extremely sensitive to the "infamous" jagged edges and alternating black lines of passive 3D technology should avoid these panels, too.

Outlook:
The combination of an exquisite design and advanced features make these LG LED-edgelit TVs stand out among their peers. What remains to be addressed is how well they can perform in our lab compared with their predecessors. And Contrary to most reports, the LA8600 is not the highest-end 1080p LED TV from LG. This accolade belongs to the LED-backlit 55LA9600, which was very briefly introduced at the Consumer Electronics Show.

Sharp's $21K TV Is The Largest LCD In Australia

Mon, 21 Jan 2013 09:33:43 GMT

The latest supersized screen to grace Sharp's range is the 90 inch LC-90LE740X. Sharp boast it is the "largest LCD TV in the Australian Market!," for now at least. They've coined it ‘viewmongous' and cite a swarm of picture enhancing features. These include Sharp's X-Gen Panel, which uses UV2A technology for more efficient backlighting; Sharp's AquoMotion 200 to handle rapid motion and Yamaha technology for "Hi-quality 3D".

It can connect to the Internet by way of a Wireless LAN adaptor and its ‘USB Time Shift Plus' function allows users to simply pause and return to digital broadcasts. But at $20,999, it's significantly more expensive than LG's 84 inch UHD television ($17,999). The LG TV might be shorter on inches, but what it lacks in size it more than makes up for in smarts.

Are OLED TVs Almost Here?

Sat, 12 Jan 2013 12:19:58 GMT

Last year, OLED displays appeared on many "Best of Show" lists of products displayed at the 2012 Consumer Electronics Show - including our own. Even then, however, we identified the OLED technology as an indicator of things to come, rather than a technology that consumers could purchase and take home.

What is OLED? OLED, or organic light emitting diode, technology is a new color screen technology that differs from liquid crystal displays by actually having the pixels themselves light up. LCD HDTVs, even LED-backlit ones, form a picture on the liquid crystal layer and must then be lit by LEDs on the edge or back, or by CCFL lights on the back. OLED, then, provides both aesthetic and practical advantages. OLEDs take the backlight out of the equation, meaning when a pixel is "black," it's literally off; there is no light coming from that pixel. This means both the screen will show better black levels and consume less power, and that displays using the OLED technology can be extremely thin.

(OLED is a display technology; the other TV buzzwords at CES, "4K" or "Ultra HD," refer to next-generation display resolutions that are independent of screen technology. Most manufacturers were at least talking about 4K televisions, based on LCD technology; 4K OLED TVs are a step further down the road.)

The problem, however, is apparently the difficulty of manufacturing the types of large displays that buyers favor. During its press conference, for example, Sharp executives noted that the market revenue share for 60-inch displays and larger had grown from 4 percent of LCD TV industry revenue two years ago to 20 percent of LCD TV revenue last year. OLED displays, which have hovered in the 20- to 30-inch range, haven't come near to that.

With the recent CES, manufacturers are edging nearer to actual production. The most vibrant sign of life was from LG, which was actually taking pre-orders for its 55-inch OLED displays, though only in South Korea. Other companies were showing off how thin OLED displays equal flexibility. Click on through to the best OLEDs of CES 2013.
