Re: Squealing from front channel
Probably some components have become thermo sensitive and are on the edge of failing. There are many components in these units, and it is impossible to guess at exactly what has failed. The receiver will require proper trouble shooting by an experienced tech to service it.

You might want to disconnect the speakers at this point just in case they haven't been irreparably damaged by the amp problem.
Try the amp 'naked" (no speakers). Does it still cycle off? Take it to a technician. If it stays up try one speaker; then the next. At some point you will either have identified the failing component/channel or the failure will have gone away (doubtful).
I would recommend checking your speakers polarity ( + on the + - on the - ). Also check to make sure the wires are not touching each other where they connect to the speaker or amp. Also check your input connections if you are not using HDMI or Optical. Worst case is you have to send it in to get serviced. Hope this helps
if front left is working it is possible u have a dry solder on ur right channel line. try resoldering or if u want to know exactly where dry solder is, shake gently every right channel components and connections. if resoldering does not work it is possible u have a faulty ouput amp for ur right channel. if ur not sure about this i suggest u get it checked by a qualified tech.
Hello.I know the post is old but i had the same Amplifire NAD T955 with the same problem.I send my Baby to a Service in Austria and they can easy repair it.Im very happy again,it works nice.If anyone had this problem contact them.Harlander GmbH in Vienna.Homepage reparatur-service.at. Greetz TommyS
Well, the nice thing about the newer amps is that the actual amp
circuitry is all contained in a module and you don't have to do much
troubleshooting. Just replace the module for that pair of
channels. Bad news of course is the modules can be pricey.
Should say right on it the part number, order it from mcminone.com or
whoever, solder it in, use new conductive grease (many times I think
these modules fail because the grease gets old, the module overheats
and toasts) and you should be fixya'd
