Ok so i have ps3 slim (cech2001b, firmware 4.31) with a replaced blu ray drive that matches the motherboard. Everything seems to work fine, however, when i go to play a game or try to use the playstation store I get a black screen and have to manually restart the system. The blu ray takes disc's, and ejects, but the XMB shows no activity. So basically my ps3 is a brick, any ideas?
I should also point out that the battery on the motherboard came loose and is no longer attached, so i have to enter the date and time every time i turn on the system.
