Problem with PS2

[budica]

Hi guys. I figured that you where all such a huge help in getting my mod chip installed that I would call upon you all again. I was able to get my mod chip (magic 3.1 in a V7) installed and working just fine. Every now and then the game would freeze and the eject would act a bit funny but all I had to do was turn off the system and every thing would be fine the next time I tried. Now, I was out at work and my wife calls to tell me that the system isn't working at all anymore. When you turn on the system you can't get the eject button to work. I've dissassembled everything and checked all the connections but every thing seems fine. Any ideas?

Thanks.
