i have a Sony MDP-650D which has a problem which h i'll try my best to explain the best i can:
after taking the cover off i found that upon inserting a disc the little tray that lifts the laser wasn't moving up and with a careful (yet firm) lift upwards it will then 'lock into place' and the disc will start spinning and the movie plays
i'm really struggling to find any into about this other then it might be caused by the cogs being missalinged and need to be ajusted (painstakingly) to get it working
any info on this or help would be amazing
