Today I had a major problem with my otherwise problem-free, (for over 2 years, Pioneer player. I turned it on, put in a disk, it attempted to load, then said open, but didn't, then shut off. I tried opening the tray and that didn't work. I took off the cover and checked things out. Finally I removed the whole Tray/Laser assembly, and after putting it back in, and really pressing the connectors down I got it to work. Has anyone seen this kind of problem before. Any other ideas. I hope this doesn't keep happening. I am thinking if it happens again I will remove the same part, but this time try and clean all the contacts as much as possible. Then put it back together again.
