OK, tried to tweak the laser but found I couldn't read the value of the 'pots' at all. So I ordered a new laser. Fitted it a couple of hours ago and guess what !!!.... We are still getting red screens on the PS2 Backups.
I have a dust free PS2 with a Messiah chip, a brand new laser and I am now stuck.
The model number is : SCPH-30003 and its PAL. Version 3. Both CD and DVD backups give me red screens.
Any ideas as to what to try next ? All other games are OK (PS2 originals and PS1 backups) as per previous posts......
Has anyone else come across this problem ?
