Hello all,
I've been having issues with my Westinghouse M2401 24" monitor taking some time to turn on. You could hear it "charging" up and then flicking off, and eventually after a few times of flicking off, it would come on and stay lit until the monitor was turned off or went into hibernate and then needed to be turned on again. As time went on, eventually the monitor would try to turn on, and for a split second you could see the backlight kick on, then immediately off. Upon shining a light into the monitor, you can see the image on the LCD screen - but no backlight.
I first suspected the caps, so I took the monitor apart and found two bulging caps (one exploded). I ordered the same exact brand/voltage/farad rating caps and replaced them and the monitor now turns on much quicker, but still the same issue with the backlight coming on for a split second, then off (the image still apears on the screen, but no backlight).
From what I can tell, since the backlight comes on for a split second - it shouldn't be that, correct? If the backlight were bad it wouldn't light up at all. From what I've read, most sources are indicating its the inverter board thats the problem.
MONITOR: Westinghouse M2401
PANEL: Samsung LTM240CT04
INVERTER: ???
BACKLIGHT: ???
I've included a album of pictures http://imgur.com/a/PkU2o showing the panel and seperate boards. There are three separate boards, am I correct in saying that the board the VGA/DVI and power connector connect into is the inverter board? Or is it the long board by the backlight?
I do possess a multimeter rated up to 1000V I can use for testing.
Here is the spec sheet http://www.displayalliance.com/storage/1-spec-sheets/LTM240CT04.pdf which looks like it contains significant information. Hopefully somebody can help me out here??
