My sony compact av system,model dav-c770 is stuck
Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown

Yes, tis unit has 2 video inputs at rear so you can connect any other dvd player sound (analog or digital) to get 5.1 channel surround sound from DAV-C770 speakers.

Headphone settings appear stuck on and cant change
This might be worth checking out...the headphone jack contacts can get sprung, and not switch the sound back to the speaker circuits. Sometimes they can be sprayed with electrical contact cleaner, and sometimes they can be resprung to make contact. Since you had the unit worked on, its possible that a ribbon cable or other wire was left disconnected. I would take it back and have the folks that worked on it check it out real quick. Chances are that something is not connected, or the software could need to be reset.
Good luck, and hope this helps.

There is a gear underneath the tray that may be broken or possibly the open close detect switch nay be bad. You will have to remove the tray,you will then see that gear.

This is a repairable assembly. It needs realigment. I have realigned many of these units with no problem as long as theres no broken plastic parts. What ever you do dont force anything.Yes there is a video input jack that can be used for hookup
