Has anyone else had this problem and is there any known solution????? I have a DAV-SC8 and liked it. However, recently it started locking up. By that I mean the DVD screen freezes during play, or simply wont play, then wont eject and wont go into standby. The only solution is to power down and back up. I can power down and up maybe ten times before getting it to work again - sometimes I just give up. Then, it will work fine for days on end. Then, back to freezing and non-operation. I took it back to the store (Comet) who sent it off for mending. It was returned with the message "couldn't reproduce problem but cleaned it". It worked for a week and is now doing the same. I've taken it back to Comet but fear they won't reporduce the problem again. I'm so fed up............please help.
