Question about Zenith B25A76R 25" TV
We were gone for six months and when we returned our Zenith TV picture had diagonal lines across the screen and after it is on for a while a steady tone came on that could not be turned down with the volume control.
Do you have a dvd or vcr hooked up to this? Is it hooked up with the a/v cables (yellow, red and white). double check the cable hookup make sure audio cord is not in the video jack, from what you are saying this will do that if it is. Also there is a capacitor on the main board believe it to be C3412 which intermittenly gives horz. lines but haven't had a audio tone with that.
