Question about NAD T763 Receiver
My nad T763 currently 11mnths old decided to loose output on both main speakers and rear speakers, but centre and sub output still work. but! centre and sub are either flatout or nothing. volume is flat out regardless of volume position unless it's at infinite db, and as soon as you move it 1 step of infinite it goes flatout again. protection circuit doesn't cut in and all modes work as normal. centre and sub obviously only work in surround modes. any clues anyone?
Hi there. Are you familiar with board level repair for such products ? Your problem is most likely hardware. Either some of the final output transistors are fried, or it's a dsp problem, a regulator, a diode, a transistor in the circuit.. it could be a lot of things. But if everything was working fine and it quit someday without a change in the system's setup, it really looks like an hardware issue ! Do you have a way in the manual, that sets factory defaults, a kind of reset ? A lot of such units do have that. Try to unplug/interchange speakers as well, a shorted speaker could make the amp go nuts as well, but i wouldn't bet on it. Still, i'd check that out. Hope that helps ! cheebster.
