Hi there, I have recently had a problem with my Sony DAV SA-30 shutting itself off with the standby light flashing. What happens is that it starts to read the DVD then after a few seconds makes a horrible click and then shuts itself off. I looked through the trouble shooting guide and it stated it could be due to something blocking ventilation grill. I checked this and no blockage. It then stated that could be due to speakers short circuiting, so I then disconnected them all but still it does the same. Its under warranty so I have taken it back to one of Sony's authorised repairers but I was wondering if anyone out there knew the what was wrong or have had similar experiences. Thanks in advance!
