Emotiva XPR-5 Repair

Hello! first time poster here.

I have an XPR-5 (400Wx5) unit I purchased on 9/17/2012.

Recently it started having an issue where I would hear popping sporadically and then the 5th channel would blink red and the unit would shut off.

I spoke to Support a few weeks ago and they suggested 1) replacing the speaker cable for the 5th channel and 2) moving that speaker to a different channel to determine if the issue is with the speaker or amplifier.

I did those steps and the issue did not follow the speaker. After 30 minutes or so of watching television I hear large popping noises a few times and then the 5th channel (this time with an entirely different speaker and cable) will blink red and the unit turns off.

Unfortunately support is now telling me the XPR-5 is no longer serviceable by them and to find a local dealer. They did provide me the schematics for the unit. I am having trouble finding anyone in the New York area who will look at this thing though.

Any advice? Does anyone know someone who would service this preferably around NY/NJ?

Thank you!!!
