Have TV Questions? Ask a TV Technician
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.
You need to use the up/down buttons on the vizio remote, or on the side of the tv, or type in 03 on the vizio remote (not the cable remote).
If this doesn't work, then you need to retune the tv - go into the vizio setup menu, under Initial Settings, and run the Auto Scan function, and from there channel 3 should work.
You've gone through ALL of these steps?
I can help, but would need specific details from you such as the model of the tv.
