Vizio 37L suddenly stopped getting all digital channels

With the same antenna that has been working fine for months. The analog channels still come in just fine, but after a storm the other day, the TV isn't picking up digital at all anymore. Any suggestions??

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!

The following is from Vizio Tech Support and it totally worked when the other ideas on this site didn't.

"I recommend clearing the TV memory, resetting the settings and re-running the scan.

To perform this please remove the cable connection and run a channel scan to clear out the existing channels.

Once this is finished please perform a power cycle on your TV. Please follow the steps in this order:
8
1- Power off TV
2- Unplug TV from outlet
3- Press and hold in the power button on the TV for 30 seconds (while it is unplugged from the wall)
4- Release the power button
5- Plug in the TV into a different outlet
6- Power the TV back on

There is also a factory reset option in your menu under the SETUP section. It will say either "reset all settings" or "system reset". I would recommend this option as well.

Once the power cycle is finished and all settings are reset. Plug the cable line back in and run the channel scan."
If I did it again i probably wouldnt "reset all settings", I would try the scanning section first and see what happens. You can always go back through all of the steps if doing only part of it doesnt work.

    Definitely took care of my problem. Been frustrated for a month, gave multiple theories a try but this one did the trick. Thankfully, was about to trash it.

The RGB technique for me worked on my four year old TV. EXCEPT, once the Vizio turned orange, I had to use the power button on the TV to get it back on. Once it powered up, I hit Input on the remote to get back to the normal TV. Then, all the digital channels Appeared!!!! YES! Thanks a bunch!

I tried all these and they didn't work. only way I got it to complete a scan was to remove the cable and start a scan. Once the scan got past where it was hanging, I reconnected the cable and it completed.

Vizio TVs ony have a couple boards inside, the tuner in your TV maybe damage but it may be a chance that you cannot get the tuner itself.

so you need to replace the main board, you can get if from this website, call them so they can provide you the part number

Sharp TV model LC-20AV1U - I need to reset it so I can get it to recognize my over air antenna after cutting cable TV


Hi Loretta,
The reason you aren't getting any channels to work on this TV is because it has an analog tuner. Now a days most channels are being broadcast in digital format and the TV needs to have a digital tuner.
In order to get the antenna to work on this TV, you will need to have an OTA converter that will receive the digital channels and send the signal in analog format to your LC_20AV1U.
Let me know if you require further assistance..

No TV broadcast picture. Is this a tuner problem?


yes it does seem to be a tuner problem , I also wonder what happens when you use the auto channel finder and tuner usually found in the set up section of the menu ? As well as was your TV working before and receiving input via the antennae but has now stopped working in this regard ? I also noted that attaching an analog to digital converter box worked fine , so your TV is capable of receiving a signal via that method , dose the converter box use your antennae input jack or a video jack to send the converted signal into your TV ? if it is using your antennae jack then it may not be a tuner problem .

Call manufacture tech support. The storm may have fried it. Don't tell them about the storm because they won't go through all of the troubleshooting with you.

Hi check to make sure the antenna is connected correctly. try tunning the channels manually and if they come up you can save them one at a time. Also try moving the antenna to a different location. make sure the TV is set to scan on the same input that you are connecting the antenna. If all that fails ou might have a defective tuner board.

I bought the same TV wich is in fact a Seiki TV, see the warranty paper. The television has digital and analog tuners so is able to receive digital channels.Our television receive signal thru a rabbit ear antenna and we had some trouble to scan all the digital channels. We had to change the orientation of the antenna to receive correctly the signals and we had to scan many times. We finally conected the TV to a roof antenna so we where able to scan all the channels of Montreal, north Vermont and north New York areas since we are living in the south shore in front of Montreal. After the scan was completed we conected back the TV to the rabbit ear antenna and the television is working correctly receiving all the stations of Montreal area with a very good picture quality.

Tv set just lost its ability to display digital channels


Your problem is definitely the input signal source to your tv. It is extremely rare where a new tv has a tuner signal sensitivity problem. The best thing to do is to replace your current set of rabbit ears with a different set of powered rabbit ears that have a higher gain rating with a variable gain control. Please note that the gain control setting is critical when setting up your tuner for auto-programming. If the gain control is set too low or too high it will result in your symptom.

If you still can't get it to work you could try buying a line amplifier which you would install to the rabbit ears before the tv. If you still can't get it to work you'll have no choice but to purchase an outside antennae as a result of your being in a weak signal area as signal quality changes by such things as the switch over to digital upcoming and environmental changes.

Using an over the air antenna I get all channels but one.


I experience the same thing on a day to day basis. The key, is location of the antenna. Depending on where your antenna is located, determines if u can recieve local CBS analog v. digitial. I actually tried sticking aluminum foil to my old rabbit ear antenna legs. to my surprise, I even picked up digital channel I never knew existed. Besides, when the signal transmit in Digital, u are already prepared. Your local CBS afilliate station will be accesable on maybe 2 or 3 channels. example:

Channel 10 analog

Channel 10-1, 10-2, 10-3 digital HD will all broadcast the same programming.

hope this helps u out.
