Have you tried doing a factory reset?
1. With unit powered ON, press the VIDEO and TONE DEFEAT buttons. 2. Display will show "AH RESET DONE". 3. Power off (from rear panel switch) and back on.

Hello Check the connection to speaker with this amp, for any short or any other fault. disconnect the outputs, ie, speakers from the amp, and switch it On, and see the protect display comes or not. If it comes, the fault is internal and the set need service. Your M3 dual Mono integrated amp, is of high output power and its outputs are protected against any overload or short circuit. If the system detect any among this condition specified above, it will show protect mode display. Never load this amp, as protection display is there, as it may damage the speaker or its internal power amplifier section circuits, may cause more money to get it repaired. OK.
Have you looked at the manual? There is no internal source that would produce 7.1 audio other than the test tones. Attach a multichannel source according to ITS manual.

That's a receiver only, so its only built in function is the tuner. You'll need a separate CD player, plugged into the CD input jacks on the receiver's rear panel.
in your phone the belt of your display are not properly set in connecter , u pls open your phone and display belt are set again that solved your problem
This happens to many of those model. The problem is usually on the power board (if looking down into with the control panel facing your belly... it's the cluster of boards to the left, front of the unit. Look in the top, under the connectors. YOu sometimes have to dissassemble the thing alot to gety to it. Also, on the main board, under all the "cards" (the input/video circuit boards) and near the front (at the back of the cards) tere are heat sink mounted regulators that often need to be re-soldered.
The whole process is a pain, and can take a few hours to do properly, so most repair companies will charge accordingly. Yeah, it's a shame they made them like they did. If it's working, it's a good unit. Aside from these common failures.
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.
