Question about ViewSonic VX910 19" LCD Monitor
I have two Viewsonic LCD's: models VE700 and VX910. The VE700, turns on, shows a gray screen for 3 seconds then black screen, the power stays on. The VX910, turns on, I see all the bootup process, when it gets to windows shows the desktop for 2 seconds then black screen, power stays on.
I have tried them both on 4 different computers, same problem. I have tried other monitors on the same computers, all work, so I know it's not a computer problem.
What can be wrong with the LCD's ? Inverter ? Backlight ?
Much appreciated. Thank you, Ed.
MY LCD SCREEN COMES ON AND SAYS OFF MODE IN 5SECS AND CUTS OFF EACH TIME I TURNS IT ON

If the monitors use seperate plug in power supply EG 12 to 24volts it could be that at fault.
Or it could be the invertor at fault.
I have had some success repairing invertors if you can use A meter remove invertor Panels & check accross the coils with meter set to ohms all the coils should read identical chances are you will find one set of windings either dead short or open circuit. This will be the faulty coil hopefully as your monitors are all the same make the coils will be the same.
Carefully desolder faulty coil & fit one that reads good from a doner board.
Look for any SMD type fuses & check or replace them & thats it I have done quite a few now using this method.
Give it a go.
