Question about Televison & Video
My TV upstairs gets all the cable channels so I do not think it is a problem with the cable company. The Vizio picks up only a few channels, some analog and some HD. I am suspecting the tuner is bad but was hoping someone may have another solution. Vizio tech support was no help.
The easiest way might be to unplug the power from the set for several minutes, plug it back in and then run through the setup procedure. You are specifically looking for the channel auto scan function.

I had the same problem with my 42" vizio. Was working fine for about a year and a half, then a month after all stations went digital, I couldn't see any digital channels and it wouldn't scan for digital signals
This is a strange go around, but it worked for me. . Tried unplugging, pushing power button for two minutes... did everything the forums suggest, with no resolve. But, here's what DID work for me. Trust me, it sounds strange, but it continues to work (and, yes... it's not a permanent fix... the channels still go out once in a while, but I can always get them back now)
Use your Vizio remote control. Turn your TV on. Press the "input" button until you get to "RGB", which is what you would connect a computer to. Make sure no computer is connected, or it's at least off if it is connected. When you get to RGB, you'll see a message that says "No Signal". After about 5 seconds, the TV will enter a sleep mode and seem as if it has turned off (orange Vizio logo). Once it completes it's little sleep cycle and "clicks" off, wait a few seconds and hit the input button again. It'll go to the next menu item. Keep clicking input until you're back on "TV", and VUALA! The channels are back!
I accidentally figured this out when trying to troubleshoot, but I'm glad I did. Didn't want to dishout $250 to get it fixed. Let us know if it works for you too!

I do not know if you will get this message but if you do. Here goes. The protron PLTV3250 does indeed have a digital tuner that can be used with an over the air antenna. You need to push "source" on the remote until DTV is selected. With this selected and your coaxial cable from your antenna hooked up to the digital connector (not analog) on the back of this tv you can then press Menu and you will see a totally different looking menu that you are probably not used to seeing and then from there you can do an auto scan for the digital channels and it works great. I have rabbit ears hooked up to this Protron PLTV3250 and this has a beautiful picture. Far better than the picture I get from just the standard digital Directv receiver. You do not need a seperate digital tuner box to use with this TV. It does indeed have an ATSC digital tuner and it works great. You probably are selecting Source "TV" in the menu and that is not what you select for this TV to use the Digital Tuner. You need to select DTV from the source menu. Good luck and please let me know if you already knew this or if this helped you. Thanks, Tom
