Having problems with your LG L1951S (Black) 19 in. Flat Panel LCD Monitor ?

Screen Blackness (NOT like all the other ones)

\015 I have seen tons of posts here about problems with the power supply board for LCD Monitors, but the symptoms of those posts aren't the same as this one. When I turn the monitor on, it flickers very dimly for about half a second, then turns off. The green power light turns orange. I am currently holding the inverter board in my hand right now, but nothing appears overtly wrong with it (blown capacitors, loose resistors, etc.) I was previously able to negate the effects of it by turning the brightness and contrast down to 0 when turning the monitor on, but now even that doesn't work.\015

Answers :

Not all inverter problems will be visually apparent.\015\012\015\012Some capacitors fail with a high ESR and the only way to check that is with an ESR meter.\015\012\015\012Output transformers can fail subtly and you may have to test them with an ESR or low-ohms meter, but even that may not be definitive.\015\012\015\012Parts can be shorted or open without showing burns.\015\012\015\012It could also be a bad lamp / bulb.

Faulty Monitor? I bought one of these Xerox flat panel 19 inch monitors to replace my convention Sony unit about 4-5 months ago. It has worked just fine until about 7 days ago. Are there any known problems with these Xerox units? I turn my computer off during the day, when I am at work. I also turn my computer off during the night when I am asleep. At those night times I also turn the 'blue power button' on the monitor off as well, as it will flash annoyingly in the room if left in the 'stand
