Moments after powering on my AIO There is no picture on the display.

This can be caused by a few problems, These are the steps to check towards a diagnosis going from

the easily accessible parts down to pulling the unit completely apart down to the LED Panel.


  1. The motherboard has not been flashed to use the LVDS connection over DVI

  2. The motherboard is flashed but has failed to produce a signal 

  3. The LVDS cable is faulty and needs to be replaced

  4. The Power inverter has failed and needs replacement

  5. The display panel itself has failed (Usually the back light or lines

     

Symptoms when booting up your AIO and what part they point to

Backlight:  When you see the backlight initiate, but don't see any
picture on screen then that usually points towards either

Motherboard being flashed
Motherboard Not flashed and has a faulty LVDS port
LVDS cable is frayed and can no longer carry a proper signal 

Backlight pt2: when you see NO initialization from the backlight but you can see a feint image
of your Bios/Login screen then that points towards

Power inverter board has failed
Panel Backlight has failed

This fix applies to the following Intel server boards:

S3420GP, S5500BC, S5500HCV, S5500WB, S5520HC, S5520UR, S5520SC, and SC5650SCWS.

Description of issue:

Server responds slowly after Windows Server 2008 R2 or Windows 7 is installed.  If the operating system installation will not complete, skip to step 3.

  • System login is very slow
  • Keyboard and mouse are slow to respond
  • Task manager shows high CPU usage

The DPC (Deferred Procedure Calls) rate increases until the system slows and is not usable.

Fix:

  1. Update the system BIOS to the latest version. 
  2. Change the PCI AER Support setting in BIOS to Disable before installing the operating system.  This setting is found in BIOS > Advanced > PCI Configuration.
  3. Connect the network ports to a network, switch, or connect both end of the network cable to different ports on the same system before the operating system loads the embedded NIC driver.
  4. Once the operating system install completes, download the latest network drivers.
