GreetingsCustomer your Polaroid TV, manufactured by Changhong as model LS21W, apparently has a controller IC or associated circuitry that is not allowing commands to be routed. There is one main input board that can be changed which is available from the following source:

It may also be possible that the remote sensor could be defective and hanging up the controller. This can be disconnected to see if the main switches will then function.

If you need additional information, please let me know.
