Recently come across an RFM that wont boot - I get a a fluorescent bulb turning on and thats it.

I've replaced the power supply, disconnected the prism card and hooked up a monitor directly to the PC and it still isnt booting(power supply fan is running). My CPU fan seems to be fried as its not turning.

Anyways the 5 caps on the board are pretty bloated and need replacing.

I've got a decent soldering/desoldering station and have replaced many of components in the past on regular pinball boards - this mobo scares me a little though because of the tiny traces..

How many of you have actually replaced these yourself? any tips to share?

Yes, I recently replaced them and made a non booting game boot. Definitely make sure you are using proper desoldering equipment and that it's 100% working. I believe the motherboard is a multi-layer board, so if you hack that up you'll have a hard time fixing it.

If you're confident in your ability, go for it. If you're not, please let a professional take it on.

I've seen far more P2K motherboards destroyed by botched cap replacement, than any and all other issues combined. Please don't take the work lightly. It's a delicate board and easily turned into a brick.

Sent you an email also, was hoping you could repair this at PAGG?

What I usually do it pull the caps off by rocking them off, then remove the two leads that are left individually by heating underneath, and gently tugging topside with a needlenose.

eek - this method sounds really scary with a motherboard like this

are you doing this on a driver/cpu board or a computer style motherboard?

Replied. Not a problem, definitely planning on being at PaGG.

Computer motherboard. I run a PC repair shop, so I'm used to doing this. There is definitely risk involved.
