Receiver TV Problem

Had a little problem with our receiver on new TV. Called the company after our grandson suggested it was the receiver and he was right. Got a recording, of course, but the recording told me just what to do. I followed directions and the receiver is working right again. There was a 7 second delay between the time you switched to a new channel and the time the picture came on. Now it is fine. Sure glad of that. I really should have remembered that from our old receivers.
