I have just modded a working PS2 SCPH-30002 Version 3 with a Duo chip.
i checked every join, seemed ok, no shorts. i put it together, fire it up, get browser screen ok.
I go and open the tray and stick in a dvd, i click the tray button again to close it and nothing happens, the blue light blinks like it wants to close the tray but nothing happens. worked OK before the mod.
I push it shut and push the tray button and it opens again but it wont close.
Ive checked the ribbon cable, pulled it out and put it back and that seems seated ok.
anyone got any ideas what the problem is??
