Hi, got one ofthese with washed out/flickering display. You can make out osg and menus when called up. Vs and Va voltages correct. Replaced 680/50 and 1000/10 electrolytics in psu. Any ideas appreciated.

Check your voltages at the Y and Z boards. Correct voltages for Vs and Ve will be on a sticker on the back of screen.
trevorsheppard:
As the Vs and Va voltage at 192 and 60volts could it be the display is faulty?

Hi,
The FET's on the Y-Buffer's give trouble, check them for shorts,

Try the inbuilt test patterns....Disconnect the LVDS cable from the control (logic) board and place a short across the Auto Gen points P1 on the control board. If you get good clear test patterns on the screen it will eliminate basically everything except the main board.
