Dell 2005FPW PS PROB AND VERT ROLLING
I have a dell 2005FPW that has 2 different problems.
the first is a power supply problem (I think). Nothing visibly looks bad but the power blinks on and off. Any ideas? (or a schematic?)
the second problem is a vertical rolling. If it were a CRT i would say the vertical hold circuit was shot. again, any trouble shooting ideas?
Any help appreciated.

Re: MS6337 ver 1
It's A, the board never worked again straight after the mod. So I take from that you are sayind a dead mosfet would not be the cause of it?
The mod was on the Celeron CPU but that still works, it somehow just damaged the board (the memory and everything else was not damaged)
The board will power on for around 1/10th of a second in a flash before it goes off again. I noticed it has 4 diagnostic leds and they just quickly flash as green red ,red ,red, which the manual describes as "early chipset Initialization". I need to find what a voltage...Last edited by bugmenot; 04-18-2009, 11:12 AM.

MS6337 ver 1
I was given an MS6337 815 pro v1 motherboard from an old computer. The symptoms are the board will no longer power up (PSU does not turn on). I have tried different PSU's and the same result, PSU doesn not turn on.
I later found out the person who owned it said it stopped working staight after he tried a pin-mod on his coppermine celeron. (The celeron still works).
I examined the board and All caps on the board are fine the only slight damage I can see to any part of the board is a chip called "CET CEB703AL" by the cpu socket. What does this chip do, would it stop...

Re: hp f2105 slow screen
My HP f2105 has the same problem. The screen has a massive delay and there are vertical lines on the screen. The menu still works in mine though. It happened all of a sudden. If you figure out how to fix it, please let us know. Thanks.

Re: Soltek SL-75DRV5
I'm planning on recapping my SL-75DRV2 (it's older than your board) w/Athlon XP 1700+. One day I was having reboot problems about 2 months ago and found a couple of those caps burst. Being the economic guy that I am, I'm chosing not to spend a couple hundred for a new system as my system has run perfectly since I first put it together (with the exception of the bad caps).

Re: Fuyjju Bad Caps
GREAT forum, thanks for the help. I forgot to mention I only replaced 2 out of 4 caps, which were the obviously bad caps (I guess the others could still be fried but not exhibiting symptoms). Problem was, the replacement caps are 3 times the size of the originals- this makes for some difficult squeezing things into the enclosure. Also some of the new caps are almost an inch off the board, however I did insulate the leads to prevent shorts. I figured if I blew a power transistor or transformer forget it, but if the buzzing could be fixed by recapping the other...

Fuyjju Bad Caps
Hi, I found some bunk 1000uF 10V Fuyjju caps in my Flex ATX power supply. Sorry no photos... Leaking electrolyte, typical symptoms of intermittent system failure. Unfortunately I tweaked around too much before I realized it was the caps, now (after recapping) I get an intermittent buzzing that sounds like either a bad transformer or perhaps a blown transistor. However I still get power, it's just not sufficient voltage or it's unstable enough for the system to refuse to get past POST. I have no test equipment so I am shooting in the dark. Anybody have any ideas?
Thx
