I have 2 reveivers and one will only pick up part of the stations. I moved it to the other TV where that receiver was working and it still doesn't work properly so I know something is wrong with that receiver. Any ideas of what could be wrong. Is it something I can fix?

Hi,
Probably not.
If you are using a Satellite company, like DishNetwork, whatever, call your customer service representative number. They might be able to program it while you are talking with them, or the receiver just could be bad.
I do wish you the best of luck.

It is a bad receiver. Is there a way to test and repair it?

From my experience, I used to tell my guys to tell the customer to not go to the repair shop. Instead I told them to simply call Bell Expressvu (Canadian Satellite provider). If it is repairable, they'll take care of it, and if not, they'll replace it.
