Yes, that is exactly the same symtom that I've seen. Those caps are toast. I've had 3 of these montitors go bad with the same problem.Radio Shack has a cap that I used to fix the last one. It's 35 V is an overkill, but won't harm anything. At a $1.59 ea. you should try it.

So it's safe to use a 1000 µf 35v capicitor?
...and we'll see if my local radioshack does indeed have one. Or three. :P

Well, I got the capacitors you listed for me at radioshack today, and I popped them into the circuit board, and lo and behold I am now typing this on my Acer FB855! Thank you so much, Thaddl!

Hi everyone...I just found this forum because of this issue some people are having with that fp855. I've had the same problem. I opened mine up and the caps that you are talking about seem to be OK, however another part of the power supply seems to be damaged/browned (like it was burning!). I took a few (admittedly, bad) pictures of it. I placed an arrow pointing to where the problem seems to be. The pics can be viewed @ http://www.cs.rit.edu/~kak2112/fp855/

The brown'ed area is around the 2 large yellow-ish rectangular-ish boxes. The 3 caps that everyone says are the problem seem to be OK. The two of them are EVER-SO-SLIGHTLY buldged, but not badly at all. Nothing is oozing out. I don't think these are the problem (but I'm no electrician!).

If anyone has any idea on how to fix this or how to order a new power supply, that would be greatly appreciated.

my problem is that the led will light up green like a signal is being received but the screen remains blank. my capacitors look fine. would this still be a power suplly issue or do u think changing the capacitors will help?
