Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
What is the make/model of the tv?What devices are connected to the tv (aerial, cable/satellite box, dvd, etc)?
Okay AV1 isn't a channel, it is an input, so if using aerial, you need to press the INPUT (source) button on the sanyo remote, repeatedly, to get back to the TV (air) input mode to get the channels back.
Do you need more help with this?
