Has anyone worked on one of these? All caps test good in/out of cct. PSU is working normally. All it does is flash the blue power LED. No specific pattern. I am thinking the upro is bad on the video board. (Runs warmer than normal, but not smoking hot). There is no splash screen, or OSD whatsoever. There is no difference if the VGA cable is connected or not.The inverter is functional when 5 Volts is applied to the "turn on" line. Help? Anyone?

Has anyone repaired one of these The PSU has been tested and working normally. All it does is flash the blue power LED. There is no display on screen it is the same if the VGA cable is connected or not. The service manual can be found here http://linfotech.co.uk/schematics/LG/LG_list.asp -
Re: Lg W2234s
1. A flashing power LED can also be caused by a corrupted EEPROM on the signal card. Some monitors can be reset by holding down a combination of switches when turning on the monitor.Originally posted by terry View Post
2. A common symptom of a shorted inverter driver transistor is a flashing power LED.
3. In some cases bad capacitors will cause a flashing power LED.
PlainBillFor a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

Re: Lg W2234s
To add one more cause to the list causing a blinking PLED,Originally posted by PlainBill View Post
One of the traces on the flat ribbon cable going to the LCD panel had come loose from the ribbon, although I did not test to know exactly what was happening, I suspect it was 5V line finding a ground.
Anyway if the blinking PLED stops when the cable to the panel is disconnected from the logic board, and you gain control of the front PLED it gives an area to look atWhatever I do, I consider it a success, if in the end I am breathing, seeing, feeling and hearing!
