V9 install troubleshooting

[jm10oc]

Hello All. Been lurking here for quite some time and never needed to ask for help until now. I've chipped and repaired quite a few ps2s but this one I can't seem to figure out.

I installed a messiah 2 1.33b. This is only the second V9 i've done and had no trouble with the first.

It will boot a backup (cd or dvd) no problem upon initial power on. The problem i'm having is that once the unit is on for two or three minutes it won't boot any backups again. If I disconnect the power and let it sit for a while it will boot again.

At first I thought maybe I had a cold solder joint causing the issue but i've been over every connection multiple times and don't see any issues. I performed the romeo mod last night and its still doing the same thing.

My question is does this sound like I have a connection issue or maybe just the laser needs calibrating. This ps2 is brand new and only used during install testing so i doubt the laser had a chance to get damaged.

Thanks for any suggestions.
