Home Theater Reciever cuts off.?

Question

I have had three different recievers with the same problem. When playing a loud section of a Standard DVD or an HD-DVD, the reciever will cut off.

If I am playing a bitstream output, such as Dolby Digital, it happens at a lower volume than the PCM audio output. I have even disconnected all speaker connections from the reciever, and the problem still occurs.

The problem also occurs with both SPDIF and HDMI. I have the reciever connected to it's own outlet and have the same result.

The volume setting is around 50% to 60% when the failure occurs. All the receviers were at least 75W per channel rms.

Any suggestions?

Answer 1

this could be only 2 things beside a factory malfunction,  there is a short on the speaker wires or the receiver is overheating.

some newer receiver shut off when the speaker wires are cross or short.

did you disconnect the subwoofer from the receiver along with the speakers to test ?

Answer 2

when all the speakers are the disconnected the receiver cuts off with volume at 60% up?? how long does it take seconds,minutes,hrs??  is your unit in a well ventilated space? does your unit produce alot of heat when that happens? need more info. start testing from a cold start, give it enough time to cool off after every test.

i assume you are using the same speakers witha all three receivers it could be an internal short in the speaker or conductor short. same issue with 3 receivers sounds like the problem is elsewhere.

Answer 3

does it have a 6/8 ohm switck

If it had happened on 3 different receivers it could be the power coming from the wall outlet.

Answer 4

I'd say you have a short in your speaker wires.  If you have a splice somewhere check it and make sure the wires are not touching or damaged.

This happened to me recently would I would crank my tunes by the pool and found a splice that had come undone.
