I was having open tray problems for a while but after ejecting and pushing the tray back in a couple of times it would work and then I started getting unreadable disc errors and now it's rendered useless. I've tried all the fixes, pot tweak, new laser, foam block, rubber band trick but nothing has worked. I read somewhere that it's got something to do with the south paw? Do I need a new disc player or is it another problem with the board?
