I have the same problem with my MacBook Pro! It doesn't boot past the blue screen, on its own, but it boots with the Installation disk. I did the Repairs and the Verify, with no problems found, but the Boot with the D key for Diagnostics (with extended testing on) cannot go past (the second letter 't' in testing) 2/5 of the blue line, while 'testing memory', I switched the memory cards (2x1G) around but same result. Appreciate any advice. Mario.

There is no fuse in the headphone. I checked with a meter after my unit had sound from only one side, like yours. Apple did not want to repair it and offered a ten percent off on the 7th Gen model instead. I opened mine with a hair dryer and carefully inspected the headphone socket for damage with a circuit tester, no joy. I ordered a headphone part from eBay and replaced it carefully. No joy either, it still only has sound from one side. It's a paperweight now. I'll never get another Apple player. There are many others to choose from now.

Thats exactly what I used. A Hair dryer. But BE WARNED, in no way it will go back to what it looked like before you took it apart. Mine separated again after some months... it's just not designed to be opened by users.
