Problem with my Carver AV-705X

[flcountrysurfer]

Recently moved cross country and my wife tore my system down while I was at work. She didn't unplug the RCA cables from it and 2 of the broke off. No, problem I figured I would just power the rear speakers from the receiver. I hooked everything up and now the red lights come on for a second then the amp shuts down and a green light by the power button comes on. Any idea what would be causing this? This has been a great amp for decades and really don't want to switch amps. Any help would be appreciated. Thanks in advance.

I'm going to guess that there is some strands of copper bridging across the speaker outputs causing the amp to go into protection mode. Take a magnifying glass and check all the inputs and outputs for any kind of debris.

Did she break the speaker sockets or those female RCA sockets? It looks to me as if they speaker sockets would be easily broken. I don't see how you could break the female RCA sockets, without using enormous force.

I suspect the speaker sockets are broken. In which case you almost certainly have a speaker output shorting to chassis ground. This would send the unit into protection and do serious damage to the output stage quite possibly.

You need to open the unit up and inspect for physical damage for a start. Any broken terminals need removing and replacing. This will require soldering skills, but probably not a difficult repair. If after repairing the physical damage it still goes into protection, then there will be blown output transistors and possibly the driver stage.

Those amps have a class G power supply which is complex and difficult to trouble shoot.

The big issue is not to cause more damage. So after any repairs of the physical damage, it would be best to bring the unit up cautiously on a Variac variable voltage transformer, but I doubt you have one of those.

If you don't know what you are doing, then leave it to an expert technician.

Yes, he likely will need a pro, as he plugged a damaged unit in, for a start.
