I've read numerous posts with similar problems and hope I can get a handle on what's ailing my Westinghouse LCM-22W3. Eventually only show: green led and desktop for ~2 sec, then black/nothing. Reboot would give same. After a few min led switches to orange.
I've fixed an lcd before (thanks badcaps). Replaced some caps on power board but got messy, so ordered a compatible DAC-19M005 replacement for my DAC-19M010.
With new power board: now upon boot I get (green led) & ~2 sec of desktop, then black (using VGA, or dongle: no true DVI cable). I can tell using a flashlight the screen is getting no image. There are no sounds.
Q1: Anyone think the DAC-19M005 is worth keeping? A post on another site says problem may only be a difference in the current protection circuit (replace one component?). Other posts surmise this problem is due to backlight issues.
I could return the DAC-19M005 and look for a 19M010 but imagine that also might give wrong current. Personally I'm smelling backlight issues.

but diodes and backlight parts start confusing me.
Any feedback would be most appreciated.
Thanx,
Mac
