    My tv is hooked up to cable and freezes after being on for about 3 hours. The only way to shut it off is to unplug it.

    I have a similar problem on a Vizio 37" LCD tv. The screen freezes (frozen) and the remote ceases to work. You can't do anything. NO buttons work, I have to unplug the tv and plug back in to get working again. It has done it twice in the past few hours but never has before. I have a fine digital signal verizon fios cable so the signal is not the issue.

    My Tv started doing it when I had to use the High number Rf Channels after cable said you needed a box. the Channels not available without a digital box were still available on Vizio Rf channels. But after hours on one of those channels it will freeze the picture with no sound. Nothing works but unplugging.
    But It ONLY happens with the RF channels. Gonna contact Vizio.

    Wachusett`s note just about hits the answer. It happens in Southern England via TV reception from Sky and whilst TV goes into freeze frame the audio continues. Until improvements are introduced the only solution is to switch off TV, then switch TV back on and problem has vanished.

Hello, your picture freezes becuase your using unstable reception like over air analog signal antenna. even with a booster you still loose signal if theres storms or weather events. try using a more stable signal like cable or satelite service even digital adapter for digital tv this may help with the freezing.

SOURCE: Frame periodically freezes on Vizio 37'' TV

Your statement is confusing. Why? because you stated " This tv is hooked up to an Antenna with a Booster", then you said it's connected to Cable Tv. I will answer this both ways for you.
If your on an Outside Antenna or Rabbit Ears, even with a booster, if the signal is not good prior to getting to the antenna then a booster only amplifies what it see's and that may be as we call it, "garbage". In a HDTV the freezing can happen when that situation is at hand, however if you are on Cable and we know the signal is clean ( we hope? ) then the problem is with the software in the set and should be looked at by a service center, or if it's right out of the box then I would exchange it.
In digital technology there's no maybe, it's yes or no! If the signal is not what's required, then you get what your experiencing now, IF, there's nothing wrong with the set, and there may be. I just repaired another brand doing the same thing and it was the Main Control Module. So, I hope I helped you in isolating the problem. Please keep me posted...

The picture on our Vizio V0370M periodically gets darker, then after a while will lighten up.


If this is a brand new TV you may have a bad video card. The other, easier but pain in the but thing is you could be switching from a HD channel to a non HD channel. You will notice a difference. Last if you have an light sensor on the TV (adjusts to surrounding light) that could be tripping but you should have an option to turn that off.

Digital TV freezes now that the digital conversion is done


Hello,

Do you remember in the old days when you got bad reception and the TV would get snowy? That was due to the signal strength of the incoming signal was not strong enough. We with digital TV you can still have a situation where the signal is weak, since you are looking at a digital picture the video and audio are packetize, and being packets they are first fed into a buffer and then sent to the decoding section of your TV. Now think about this when the signal becomes weak and the data stream is corrupted to the point that the processor rejects the stream that data which is in the buffer plays out and the last thing in the buffer is what you see on the screen (frozen image on the screen) until the signal strength goes back to normal and the buffer fills up again.

How do you stop this, well that's a hard question since the buffer underflow is the result of signal degradation, the cure would be to prevent the signal from degrading. This can be done with the use of an HDTV antenna (too expensive), an amplified antenna (priced ok for some but still too pricy for most), a rabbit ear type antenna with an amplifier added (this will work for most people), or just a plain set of rabbit ears (dipole antenna). All of these are options that can help you.

I hope this helps

Thank you,

Same problem


Then I would say you have a problem with the Main Board in the 37". Have it looked at by a service company in your area if he wants to work on a Vizio. Parts are difficult to obtain at times.

Can't get digital channels on 37


Bob,

Are you certain you've connectet the antenna coaxial cable correctly?

There's 2 of them on this TV, one for digital and one for analog/cable connections, make sure you're connected to the correct input for digital TV.

If you're certain you've got it connected correctly then your problem is going to most likely be in the TV tuner board inside the TV.

Good Luck!

Just the one TV freezes


hello, it possible if your sharing the signal to sometimes loose reception you should have a dedicated hdtv antena or hdtv cable service for your main tv.
you can check by removing all the other sets and see,
if it happens again then you need a dedicated hd antenna or signal. this should be better for you and your hdtv reception.
