What useually happens is that when one amplifier goes faulty the sensor detects DC voltage on the faulty channel and switches it into standby and disconnects the loud speakers to save burning the speach coils out and puts the system into "safe mode".
It is not the sort of repair that I can describe how to fix it online. Sorry but it sounds a bit expensive to repair, The output stage is possibly faulty on one channel only.

I would try to localize where the sound is coming from--take back off and listen when set is turned on---from speakers or from inside the TV.

Why does the red light click to green without the speakers on?


That system responds to signal input, ie an electrical signal present on the input, in order to turn on the internal amplifier. If it is turning green without any input from the source, it could require service. It may be responding to static electricity...

The speaker should go to sleep after ten minutes or so, turning from green to red again.

Sounds like either a motor mount is out or got play in the drivetrain. pop the hood and while in park push and pull the car to see how much movement you get with the engine. if it is a motor mount youll see alot of movement if it is tight and still hear a bang it is in the drivetrain.

IE.... axles/transmission.

Speakers suddenly dead?


Investigate the "no green light" condition -- did some animal chew through the power-cord? Did some child pull the power-cord out from the outlet? Did your room-mate go on an "energy-conservation" binge, and turn the speakers off?

My p.a. amp makes a loud bang after ten minutes


DO NOT use while this problem exists as you may damage your speakers.

You may be overheating the unit and the thermal cutouts may be opening... CHECK that the fans and vents are all in good order.

Check that you are not putting speaker loads LOWER than the rating of the amp onto the amp.

We can only guess at what brand you might have.

First check for loose cables. Then check how warm the unit gets.

If you suspect thermal problem, then put it in freezer for a while and then see if it "lasts" longer. If it does, the problem is likely thermal.

This could be a failure that is very hard on your speakers.
