Hey there. First post, but have been reading a bunch on this site to try to resolve my query.
I have a 22" Emachines L22YCET (I know, thats the first problem. lol).
Its about 3 years old, and now the backlight is not lighting up. Exact same symptoms as a bad capacitor diagnosis -- screen turns on for 1.2 sec then backlight goes out, but lcd is still active (if I shine my headlight at the screen I can make out the image - even access monitor menu).
I first tried turning down the brightness and contrast to see if I could get a little staying power out of the monitor before it goes black, but thats a nogo.
So I've cracked the case open and taken out the power supply board to inspect for bad capacitors. Problem is, that I am seeing no bulging or leakage that would indicate a bad cap. I do not have a volt meter to run a continuity test either unfortunately. So I was thinking of just replacing all the capacitors on the board.
But before doing so, I thought I would post here to see if anyone had any insight on my particular issue.
Im attaching a pic of the power supply board. I have circled a capacitor that looks suspect -- It doesnt quite look like its bulging, but _something_ looks a bit off Im thinking -- but Im no expert. =\
(full size link below the forum pic.)
Thanks for Looking.
