How do i get my westinghouse to recieve signal it shows on the tv no signal and on the box it says that the tv does have a signal

Make sure you have the TV tuned to the proper source.

My TV has multiple input sources ranging from the cable box to various AV and gaming equipment and I must select the right input source in order for the TV to receive a signal.

On my controller, there is a button at the top for selecting the input source. I can cycle through all sources by pressing that button. If you're using a programmable universal controller, that function may not be programmed into the universal controller so you may need to use the original controller that came with the TV.

If, after you've cycled through all of your available sources and still get no signal, check and see if a wire has come loose between your cable box and TV, either at the cable box end or the TV end.

Hope this helps.
