Hello All,
I have a Gateway FPD2485W (2485) that was doing the "two seconds to black" thing. Having read the capacitor issues on the 2485 here and having done power supply capacitor replacements in the past on other electronics, I ordered a capacitor kit and changed all the capacitors. Upon testing the 2485 after capacitor replacement, the display did not work AT ALL. Everything else about the 2485 appears to be working perfectly, the powerup, button strip, PC recongizing the device, tested USB ports, etc., everything other than an image cannot be seen at all.
Suspecting that one of the solder connections was faulty, I re-removed the PS board, and touched all the solder connections on the caps I'd replaced.
This is where the "story" gets odd/interesting... I then moved on to the Inverter Board and got lazy, and did not remove the board from the 2485 since the leads were exposed, I reasoned that I could tin the iron, and reheat the exposed lead at the circuit board. ODDLY, when I touched the + lead on one of the two caps, the whold board DROPPED about .25". I then removed the board and found I had not trimmed ONE "+" lead from the capacitors on the Inverter Board. I corrected the problem, and still have the same issue.
It seems to me that due to my ignorance the Inverter board is now toast... OR possibly damaged the section of the PS Board that supplies the Inverter. I'd still like to repair the 2485.
I only have a RadioShack Pocket digital Multimeter for test equipment, can anyone, would anyone PLEASE give me some guidance on how to isolate the problem to repair/replace the faulty component(s)???
Thanks in advance!
