It's not the TV, it's the DVR. My TV looked weird on channel 4, which is what I had my DVR set for. It is the DTA880, which does not have a channel 3/4 switch on the back. I tried to change the setting to channel 3, and now all I get is fuzz on the TV. How do I reset the DVR to factory default when I cannot see the screen?
JA: What's the make and model of your tv, and can you guesstimate how old it is?
Customer: It's a Magnavox
TV built in 1994.
JA: Does the TV menu work? Do you have the same problem on all sources/inputs?
Customer: I have no way of knowing. All I see is fuzz on the TV. If I were able to actually see the menu I could answer your question.
JA: How long has this been an issue? What happened right before this popped up?
Customer: It just started tonight. Before the issue happened I turned on the TV, which was on channel 4, and the picture looked out of whack. That's when I accessed the menu, changed the input to channel 3, and I've had nothing but fuzz since. I've been watching over-the-air TV for about a year and it's never been an issue until tonight..
JA: Anything else you want the TV expert to know before I connect you?
Customer: Yes -- how to reset the DVR to factory default.
