Hi I have two TVs and two receivers, one of the receivers and TV work just fine. The other TV receiver continually has audio sync issues. If I turn off the receiver and turn it back on it synced then there's a little skip about a minute in and it goes back to being unsynced. 5 unplug the receiver waited 15 minutes plugged it back in waited for it to do its thing turn the TV back on it still doesn't work. Any other advice?
