sorry to hear that kross..hell man my ps2 goes from home to my hotel then back home then back to hotel then back home for the weekend..constantly gettin hooked up and in my travel bag...i've never had any probs..i did read that if u used it on its side there is a good chance to damage the lens. im surprised it plays upside down because it is only magnets that hold the disc in tray..must be good magnets;) ..sounds like at 1 time or another the lens has been damaged..a cleaning kit is really the only thing i can tell ya since u have tried all the other tricks..sry
