Vizio 48" LCD won't pick up all cable channels

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.

SOURCE: Vizio 37L suddenly stopped getting all digital channels

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!

Hey, most stations are not broadcasting analog anymore. That is why you are only getting 10 channels.

SOURCE: built in tuner not working since digital transition

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

SOURCE: I have a VIZIO LED/LCD VF551XVT hooked up to a

I have the same set, same problem with one of my MOTOROLA boxes, but not with another. I have a SONY TV that works fine with this new MOTO box, but the new VIZIO does not. The audio is coming through the HDMI cable just fine, and the fact that it works when you cycle power on your TV means it's the SYNC between the TV and the BOX. I have the identical problem and am taking back the MOTO box for another one. I spoke to VIZIO for about 45 minutes trying different things. They think it's the MOTOROLA box, COX (my cable company) thinks it's this particular box, who knows.

MMy Vizio 32" tv only gets 16 channels


If your Vizio TV has a built-in HD converter, 16 channels is what you can expect. If the channels are identified with decimals such as 10.1, 10.2, etc. they are HD. The cable connection you refer to must be connected to an antenna, otherwise you would have a cable box and a monthly bill from some cable company

My Vizio LCD HDTV isn't pickup up all of the cable channels, but my other older TVs are?


Did you retry a working TV again on the same input, as it looks like a case of loose contacts in the RC Jack, cable or connectors or some strands of the cable touching the ground. Then check whether your Vizio TV supports the system/format of the cable. If your cable is licensed to be used only with the other TVs, like sensing the identity of the PC used, it could also be a problem

I think you are confusing the channel on the tv and the channel of the cable company that is not something that you can pick up with the scan tv, scan tv is good for picking up local channel meaning air channel that we get with a antenna only not the cable chanel

I can't scan DTV channels on my vizio 52''


do you have antenna or cable? if you have antena hook directly to the coax, go to menu, TV, tuner and pick antenna and scan. If you have cable hook directly to your coax repeat the previous step but pick cable instead of antenna. Notice if you have a cable box, you will not need to scan for channel since it will be on channel 3, 4 or any other input you may use.

Auto Search for Local channels not responding


Hi elmergdavis,
Check and make sure your tv is set to CABLE and not to AIR or ANTENNA. This setting is usually just above the Auto Search utility on the meNU.
Let me know what you find and I can provide further assistance.
