V7 gh-22 motherboard problems
Hi, I bought a broke ps2. The guy had failed in his mod chip install. The motherboard looks in good shape-so I am hoping to save it. I am fairly certain he bridged some points but I'm not sure where. I say this because the ps2 does work with this motherboard but it shoots out the eject tray very fast. In fact it shoots it out like a rocket and keeps spinning until you manually switch off the power. I'm just wondering what part of the motherboard controls this-so I have some idea of where to look. Besides visually seeing it bridged-how can you tell if a point is bridged? Can you test with a multimeter for this and if so-how?

Oh yeah looks just like it-sends the eject tray out like a rocket. It seems like points are probably bridged somewhere but hard to find. If I had some Idea where to focus in on the motherboard it would help. Darn, and I was hoping you might know spedmetal. Anyone else got any ideas?

Best thing to do would be to ask the guy what chip he tried to install and get the diagram. As for multimeters, if two points are directly joined together (short), it should read 000 or beep, or both.
Next time you mod a PS2, if you check the chip when the BIOS is wired up, all the points on the chip communicate with each other with the multimeter, but it will only beep when you touch a wire with the correct corresponding point...  If you touch two legs on a chip right next door to each other, it should show a reading, but it shouldn't show a short. If it does, you may have a short...
