It is most likely going to be a defective power supply but there are some other circuits that can cause the problem. I would start by unloading the power supply.

    say for instance you have a shorted audio amp in the set, this would not allow current to flow to that circuit thus causing the set to shut down. If you disable the audio circuit then the current would be able to flow, allowing the set to work but with no audio thus identifying the audio pcb as the defective circuit.That is what is meant by unloading.

How do I bypass a knock sensor on a 2000 Nissan frontier


The pcm uses the knock sensor to monitor for engine knocking, and adjusts ignition timing based on this. If there is no knock sensor present, you will wind up with a hard fault that will keep the check engine lamp on continuously. Also, the truck will go into a more conservative driving mode to prevent knocking.
The knock sensor for a frontier is not terribly expensive, but it is a pain to access on nissan v6s, under the intake manifold

Tv will not knock off or come on,keeps tapping


Sounds like you have some bad capacitors that will need to be replaced ... if you are not qualified to do it yourself and the TV is not a high end unit, your best bet is a new TV. As far as knowing if it is on or off ... unplug it, wait a few seconds and plug it back .... most TVs will be in the off mode when you first plug them in. So then you will know it's off.

Knocking noise coming from Whirlpool Gold refrigerator


I also have a new Whirlpool Gold fridge (bottom freezer with French doors) and it was making a knocking sound. The knocking sound would start when the fridge kicks in and starts running to cool, and would last for about a minute or less and be a slow knock.
I called Whirpool customer service since it is new and on warranty. They sent out a technician and he said the knocking is from gas/air built up in the copper tubing for the freezer because the copper tubing is too cold, and when the fridge first turns on it forces the air through, making the knocking sound.
His "fix" was to adjust the copper tubing so that it is closer to the heat of the motor/compressor and heat of another copper line so that the cooler line stays warm so the air/gas doesn't build up. His fix worked slightly, but the fridge is still knocking, just not as bad and not as long - it knocks fast for about 5 to 10 seconds instead of a minute.
Going to call customer service again soon and see where to go from here.

make sure the shifter and the linkage are greased, if the grease got washed off it could be the problem.
