I just fixed a CECHE01 80gb console that had the
exact same symptoms. It needs a new blu ray laser, you can get it at
www.gadgetresurrection.com for just north of 50 bucks. Search YouTube for a video on how to do it, supermodchips has some very good multipart videos to keep you on the right track. I did mine when it went (MGS4 console) and another that I got off craigslist. Its really easy, if you are even a little bit technical and can follow directions and have a little patience you should have no problem. Just make sure when you put it back together and turn it on hold the eject button with no disc in it and wait till it beeps (should take around 10-15 sec) so it resets the Blu-Ray Drive and your disc doesn't get stuck the first time you put it in.
