I have 2 v7 consoles that have the same problems. They both have a Matrix infinity in them. 1 system was working fine for over 1year with the chip and the other was working good for almost 1 month. The other day i went to turn them on and they both just sat there with no video and no blue light. The cd drive would not open and it did not attempt to spin at all either. I have read other posts on here that suggest the BA chip to be the cause of this but when i went to measure if the BA chip was ok i got a reading of 1ohm for pin8 meaning it wasn't grounded and still ok, right? I also checked PS11 and PS12 - they both are ok? Does this mean the other BA chip (BA6444FM) is bad? Can anybody else point me in any other direction as to what to do next?
