OK, I really hope you guys can help me out here:

I have a GH-022 mainboard in a PS2 I'm repairing. When the lid was removed, the Reset/Eject ribbon was knackered and it wouldn't power up. So, I switched the Reset/Eject with another and now we have the red and green lights and it powers up. But there is no fan/no DVD Drive/No noise/No Picture. I'm thinking it's the mainboard fuse as all cables are in correctly, but one question - Where is the mainboard fuse on the board? I know spares are stocked at Lik-Sang.com and I'm pretty sure after checking everything else that this is the problem. But where is it? Thanks a lot, if you got a piccy or know of one, or can just give me a description of where it is, that'd be SOOO fantastic! :)

Thanks a lot...

The site with the fuses is down :(

I can't find the fuse anywhere. It may also be known as an SMD fuse? Any mod installers know where this stray, afforementioned fuse may be on a GH-022? Thanks a lot... LUFCfan :)

Well there are like 14 fuses on a PS2 mother board. Of course every version is different. They don’t look like the normal fuse that you might be looking for. They are surface mount fuses (SMF). They are labeled on the mobo like PS1, PS2, PS3, - PS14. They are black and square shaped. Some are very small like .4 amps.

I'll try and email you the V7 fuse chart.

Oh, are these the fuses I need to check on the board?

If so, how do I check them with my meter and how do I know if they are dead? Thanks a lot... LUFCfan :)

Yes those are them. You just put your meter on continuity and check for a connection between one side to the other.

No, a continuity tester will read the resistance of the fuse without it being switched on. They all appear to be fine, but there has been a bodged chip install here, and that is why I think there is now a more serious, underlying problem I've uncovered...

Everyting else seems to be fine though. Anyone want a GH-022 for spare bits???
