Hi @lawnguy ,
It appears as though there may be a problem with the amplifier section of the receiver.
You need to open up the receiver and check for any stressed components on the circuit boards, i.e burnt out components or blown or domed capacitors etc.
Unfortunately I couldn't find a schematic of the receiver online, you may have better luck.
You could also check if all the various power rails in the receiver are OK and are supplying the specified voltages.
If you see anything amiss, post some pictures back here.
Here's how to do this. [guide|21499]
