Re: Dell E172fpb
Having a little trouble understanding the transistor testing. Would anyone care to help?
1. I leave them on the board, or unsolder?
2. test with a meter on diode mode
3. none of the legs should read full contact (0000) or open (1) on meter
Correct?

Re: Dell E172fpb
Ok, got the new caps in, and tested the picofuses. Monitor still is dark, but with flashlight I can still see the images.
I'll read up and test for shorted transistors next. ugh!Leave a comment:

Re: Dell E172fpb
I had no idea there was one. I see it now, PF 751. I will check when I grab my meter, its at home, i'm at college. It looked like a regular diode. I have three of the lelon caps that everyone says are bad, so I will start by checking the fuse and replacing the caps. At this point, the panel is from 2003, so I'm not sure the ccfls are any good to begin with... They don't look burned..
More to come when i grab the meter!...Leave a comment:

Re: Dell E172fpb
Found one of these monitors the other day. The screen is dark, but I can see images on the LCD with a flashlight. I took it apart, but the caps all look ok and the solder joints also look perfect on both boards.
Is there a way to check if the ccfl lamps are bad? I'm still in the process of reading all 23 pages, made is about 1/4 of the way through...Leave a comment:
