Ps3 slim won't read discs
Hi, my PlayStation 3 slim 120gb will not read discs I put into it. I was watching a blu-ray film, the movie froze towards the end, I turned off the ps3 and off at the wall, and left it a few hours. When I turned it back on, I ejected the blu-ray movie, tried putting a game in and it did not read. When a disc is entered, the console makes 4 ticking noises instantly after the disc being inserted, then makes an ejecting noise but not ejecting the disc (almost as if it is stuck) and then it ticks another 4 times, and there is no disc spinning noise neither the game coming up on the screen. Very very rarely, I will enter a DVD, and it will fluke and read the disc and work fine, but I recall the DVD's that have been read happen to be at least 1/2 millimeters thicker in height than a ps3 disc. Maybe this could mean that the reader is not blown but there is something jammed stopping the discs from being read?
