PANASONIC LED TV BLINKING ERROR CODE DETAILS.

noreply@blogger.com (Unknown) — Wed, 25 Apr 2018 11:37:00 +0000

PANASONIC TV BLINK CODES FOR REPAIR.

The number of flashes is an error code. Count the number of flash. It looks like one of the boards in your set is failing intermittently. Panasonic codes for a guide as a starting point. Exact board STILL has to be verified;

One Blink: One blink of the power LED indicates a problem in the inverter circuit located on the LCD panel. The inverter board is not to be repaired in the field.
Therefore a replacement is required.

Three Blinks: Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP board is repairable. Therefore the use of an ohmmeter and peak-hold-voltmeter is required to determine the cause of the shutdown. An over-voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the AP board, A board, or the LCD panel.
Five, Seven, or Eight Blinks: The A board is responsible for

Five, seven or eight blinks of the power LED. The MAIN +3.3V, MAIN +5V, and MAIN +9V sources are all produced on the A board. The detection input pins of the MPU, IC1100, monitor for their presence.

Four or Six Blinks: The AP board is responsible for four or six blinks of the power LED. The DTV9V, and SUB_5V sources are produced on the AP board. The MPU IC1100 monitors for their presence when the unit is connected to AC Power. A short or open circuit on the A board may also be responsible for their absence.

Nine Blinks: Nine blinks of the power LED is due a short circuit in the audio output circuit (s) of the unit. The audio output circuit is located on the A board. Confirm the status of the speakers. If defective, perform a replacement. If ok, replace the A board.

Ten Blinks: Ten blinks of the power LED indicates a malfunction of IC4200, the frame converter. This IC resides on the A board. Therefore ten blinks of the power LED requires the replacement of the A board.

ALL ABOUT SOUTH BRIDGE CHIP SET VOLTAGE AND SIGNALS IN LAPTOP AND DESKTOP MOTHERBOARDS.

noreply@blogger.com (Unknown) — Sun, 25 Sep 2016 05:13:00 +0000

IT IS VERY IMPORTANT FOR LAPTOP AND DESKTOP MOTHERBOARD REPAIRING, WHAT ARE THE MAIN FUNCTIONS OF SOUTH BRIDGE IC.

1.RTC circuit: Southbridge internal real time clock circuit, also called CMOS circuits, mainly used to store the time and date and ESCD (Extended System Configuration Data)
.

2. Return circuit (module): is part of the South Bridge internal power management module, all the signals are thus SLP module circuit is completed.

3.VccSus: back module (module restart) power ICH4 inside, there are three V5REF_Sus VccSus3_3 VccSus1_5 and power.

Wherein VccSus3_3 return module I / O buffer circuit power;

VccSus1_5 is mains voltage return module '

V5REF_Sus return module 5V reference voltage input.

4.PWROK: This signal is sent to the ICH4M representative ICH4 core voltage of the normal power-good signal from the outside, when PWROK canceled, ICH4 will refer PCIRST #.

It is worth noting that in three of the RTC clock, PWROK failure. So as to ensure ICH4 produce normal PCIRST #.

5.VGATE / VRMPWRGD (VGATE / VRM Power Good): This is generated by the CPU core power manager output power to the representatives of CPU ICH4 normal power-good signal.

6.CPUPWRGD (CPU Power Good): This is ICH4 output to the CPU power of a good signal, is connected to the CPU. Southbridge asserts this signal is intended to tell all the CPU power is normal, you can put on standby. This signal is internally ICH4 after PWROK and VGATE / VRMPWRGD phase formation.

7.RSMRST #: Southbridge desired return module reset signal input.

8.SUS_STAT # (suspend statas): Pending status indication. When this signal is referenced, the system will enter a low power state.

9.V_CPU_IO #: CPU's I / O power supply, Southbridge need this power to the output interface signal processor.

10.SUSCLK: South Bridge RTC circuit generates hang clock used to refresh external clock chip as used. Often used in the IBM, SONY and other machines. In standby, when the clock to the motherboard EC / KBC (usually H8S) later, EC / KBC will enter a low-power mode, then jump into the H8S own shock wave state.

11.SYS_RESET # (system reset): This signal is input to Southbridge Southbridge and dried after debouncing will be forced to reset the internal logic of Southbridge, enabling the machine to reboot

TOSHIBA LAPTOP RESTARTING PROBLEM SOLVED (NEC CAPACITOR DAMAGED).

noreply@blogger.com (Unknown) — Thu, 24 Sep 2015 14:16:00 +0000

Toshiba Laptop Repair, Satellite L300 / A300 Restarting Problem Solved.

The problem is very common in these models of notebooks (Toshiba satellite A300 and L300) freezes or restarts on AC power plug in.
It works on battery power and charges when power is connected on shutdown.

When it’s powered on with the AC plug connected may freeze when on, or remains on for a little while before freezing or restarts.

This should be done with a IR Soldering station, but can be also done with a Hot air station or Hot air gun.
1. Remove all the removable components from the motherboard like Ram, Wireless card, CPU etc.
2. Cover the surrounding area near the capacitor with aluminum foil and apply some flux paste (soldering paste) all around the capacitor.
3. Using a Hot air gun you can start to heath the capacitor and use a tweezers to touch it from the side. When it is moving that means that the soldering alloy reached the melting point.

4. Remove the bad cap with a Suction pen, and apply the new capacitor in the same position as the old one all this under the Hot air gun flow.
Keep flowing for approximately 60 seconds after you placed the new capacitor to allow the solder alloy to re melt.
5.Let the motherboard for 30 minutes to cool down, after that make sure the capacitor it is perfectly welded on the board.
6. Reassemble the laptop for testing.

Another solution.

Use 4pcs 330uf 2.5v capacitor.

DESKTOP MOTHERBOARD SOCKET LGA 775 PIN DAMAGED SOLUTION

noreply@blogger.com (Unknown) — Wed, 23 Sep 2015 14:13:00 +0000

SOCKET LGA 775 PIN REPAIR METHOD.

SOCKET 775 DAMAGED PIN REPAIR METHOD.

Tools:
1 pair of angle point tweezers - others work but I liked flat angle points.

1 Stanley or break off tip wide flat knife. It needs to be wide so it’s strong. Set the blade projection to about 1.5 inches from its sleeve support.
1 steel pin - standard dress maker’s type.
1 pair of wide nose pliers - to hold pin.
1 pair of sharp scissors.
1 x Strong 'halogen type' pedestal light - being able to position and angle the head of the lamp is a big help when viewing the project through the magnifying glasses. Aim it so that you have a great close up view.

Materials:
1 reject 775 socket from dead board - this is where you will get the pin/pins needed. Keep an eye on your local PC shops skip bins - or preferably just go ask their technicians for a dead 775 bare board.

Start

1. Prepare pin: Use a flat blade screw driver and lever part of the socket from the dead board. As it breaks away keep all the pieces for they contain your needed pins. From a broken piece of socket gently pull several pins - depending on where the solder broke on the base of the pins, some will come out the top easier and others the bottom. Just cruise along - take your time.
The object at this point is just to get some nice stock for the project. You will drop some and others will flick off the tweezers, so several will likely be needed. Pickup a virgin (unbent) pin in tweezers - hold it by its top - and use the scissors to cut off the solder bulb on its bottom, at the bottom of the "V" above it. Place it carefully to one side. You may need more if you drop it later but you can cut them later as you need them.
Note: don't unfold the pin as the pin/barb combo is used here in it’s entirety - i.e. pin, barb and the spring effect from the folded material - less only the solder bulb (that was) holding it to the PCB.

2. Now - onto your motherboard

Prepare the broken pin: Each pin leg is in a separate hole, the same as the holes you just pulled the needed pins from. The pins are made from one piece of metal. They are folded and the front is the pin and the rear is the barb - holding the pin into the plastic socket hole and also it provides the solder leg, which we need to cut off - at the "V" just above the solder bulb.
Ideally the broken pin should be broken at its shoulder - not at the bottom of the neck below the head!! This is where they usually break if they are played with in straightening attempts. So if your problem pin is broken at the base of the neck, we are going to break it again - this time at the shoulder, before it narrows down towards the head. So using the tweezers grab the pin as low as you can to the plastic socket - ideally right on the socket. Now while you hold it tight, wiggle it back and forth, rocking the tweezers at the same time to increase the abuse on the metal - until it breaks off. Now we have a normal folded pin, in the socket and broken off at the shoulder!
Next use the dressmakers standard sized (1.25"?) pin - held firmly in the pliers - to push the back portion of the pin (I call it the barb) slightly forward from its resting place. The gap created is where we you are going to push the new replacement pins barb.
Pickup the material (new) pin, you previously found and removed solder bulb from, and holding it the same way as it needs to be - place the barb firmly but gently in the gap you just created. If you drop the pin, invert the motherboard on some white paper and tap it to recover the pin. If it’s lost (make sure it’s not on your board where it could create a short circuit later) get another pin and chop the solder bulb at the bottom of the "V" and use that.
With the new pin (and it’s barb) now behind the old pins barb, pickup the Stanley (or other brand of break off tip) knife - place it vertically, with blade tip between the pin and its folded barb and with point of knife on the top of the steel fold - on the folded side.
What you are going to do here is use the top edge of the fold to push the full barb of the new pin in behind the others barb. Now - using the adjoining pin barb tops as a level guide - push hard to seat the new pins barb top at the same level as the others. This will ensure that the pin projection at the front is the same as all the other pins.
Once the top of the new pins barb is level, using the knife again, tilt the pin neck to the same angle as the others. NOTE: It pays not to touch the pins head - as the pins head is too delicate and it will break off at the base of the fine neck. So, lever on the pin, using the knife, only along the neck – preferable near it’s base – otherwise you risk bending the neck itself, rather than the area below the neck, to position the head. There is plenty of neck length to use.
Now - look carefully at the pins head - the idea is to have it nestling into the shoulder of the pin in front of it (though higher), when viewed from above. Have a good look at all the other pin head locations to become comfortable with the exact location needed.
To align your pin head (back and forth), using the neck only, Use knife, held with blade horizontal against the vertical part of the pin, below the neck, to push it and its barb back against the socket pocket's rear wall if needed - ideally you should be pushing on the old pin and its barb, so using it here to also hold the new pin against the rear of the pocket. This is the contact point between the two pins which will convey the electrical current. Otherwise, if barb is not hard against rear pocket wall, the pin head will be too far forward.
Note: If the top of the barb is hard against the rear wall of the socket pocket where the pin is located AND the barb is pressed into the socket till the barb top is level with the others, then this pins head projection, forward, will be the same as the others.
If the head is now sideways from its needed alignment, use the knife edge against the neck, to align it with careful pressure - as required. The intention here is to locate the head, laterally, by bending the pin BELOW the neck/shoulder.
Finally, use the knife to set the pin head level with the others, again using only the neck as the pressure area. Once the pin head is aligned it should look in line with the others from all the X, Y and Z (i.e. forward/back, left/right, up/down directions).

Testing

If you wish to test your new pin use a meter, set on continuity and place one contact on the pin and run the other along the resistors next to the socket position to find a continuity point. Once your meter beeps - if set to beep - or shows a continuity signal - you have proved your repair.

COMPATIBILITY LIST OF SUPER IO IC IN LAPTOP AND DESKTOP COMPUTERS.

noreply@blogger.com (Unknown) — Wed, 28 May 2014 13:59:00 +0000

SUPER I/O CONTROLLERS.

SIO(SUPER I/O) is an integrated circuit on a computer motherboard that handles the slower and less prominent input/output devices shown below. When the Super input/output was first introduced in the late 1980's it was found on an expansion card, later this chip was embedded into the motherboard and communicated over the ISA bus
. As ISA began to no longer be used with computers SIO communicated over the PCI bus. Today, super I/O communicates through the Southbridge and is still used with computers in order to support older legacy devices.
Computer devices handled by the Super I/O

*Floppy disk controller.
*Game port.
*Infrared.
*Intrusion detection.
*Keyboard and mouse (non-USB).
*Parallel port.
*Real-time clock (RTC).
*Serial port (UART).
*Temperature sensor and fan speed.

All About HDMI (High-Definition Multimedia Interface)

noreply@blogger.com (Unknown) — Tue, 27 May 2014 03:26:00 +0000

DETAILS ABOUT HDMI PORT

HDMI connection (High-Definition Multimedia Interface). What is it exactly? HDMI is a HD cable to connect multiple electronic devices ranging from home entertainment to the computer but the difference between an HDMI cable can replace some functions at once.
The most simple example like this, if you want to connect a DVD player with TV,

you usually need a minimum of 2 cable is a cable for audio and one cable for video. With the two HDMI cables can be combined into one, so installation is easier and no hassle. With an HDMI cable then there are some transmissions that can be done is replace the video cable, cable audio and last is the data. The presence here is not limited to HDMI cable is only as versatile but also has some advantages over regular cable that is: Has speed data transfer rates up to 10.2 GB per second that will produce quality pictures and better sound. Communication 2 directions.

HDMI is also capable of communicating in two directions so that the tool that one can interact with each other. In this case, eg, an HDTV (High Definition TV) with DVD Player, simply can communicate with each other to get the best settings so that images appear in an optimal fashion. Use an HDMI cable of course can not be used directly because previously you have to ensure that the appliance you have already support this HDMI connection. But as technology itself, an HDMI connection will become the standard connection such as a USB connection that already exist on all computers. Hdmi latest development of this technology which is marked by the launch of an HDMI ver. 1.4 is able to make an HDMI cable instead of an ethernet cable. But perhaps as a data cable, HDMI has a shortage of long HDMI cable itself is recommended between 70-30 m only, while for more than that, we need additional tools.

STEP BY STEPS HOW TO PUT UNIVERSAL INVERTER BOARD IN LAPTOP.

The use of a universal inverter is an alternative way to overcome the damage to the laptop inverter. Maybe inverter Original / same, hard to come by. And if there are usually very expensive!!! Or with the aim to reduce the cost of the inverter itself.

Basically all the same laptop inverter, depending on the voltage it works. There was a 9-5V or 20V, depending on the type of laptop.
Try to look at the picture below ...

If we want to replace the inverter, so that we need to know is the position + POSITVE ; -Gnd as a source of electricity, and the ENA (enable) and DIP (to control bright / dim). Term other than ENA = Light On / DIP = Adjustment.
Then you can replace the inverter of the inverter used / universal inverter with the same voltage.
Inverter that I use to replace here, Universal inverter type, you can get it here.

In the picture is very clear, you just connect VIN = + U / ENA = ON / DIP = ADJ / GND = GND.
Not easy!!!!
Congratulations Creating .. Be careful.!!
