Open Question

Vizio Gv42lf will not tune digital channels

I have a vizio gv42lf (about 2 1/2 years old) and it will not channel up or down from the remote. I go the the cable setup menu and scan for channel, and it finds 81 analog channels but does not move the digital channel bar graph. I have to cancel out of the channel scan. It still works great for analog channels, A/V inputs, RGB inputs and HDMI inputs.

SOURCE: thinking about buying a used Vizio 42"

Don't buy it. VIZIO is not standing by their products.

My GV42L had issues from the ssart and now it shows No Signal and shuts of in 2-3 seconds. I read many similar issues on this site with VIZIO.

Well you need to do some troubleshooting first. No pictures/No sound can be caused by failed 12v/24v power supply section due to bad caps, or it is not getting the PS_ON signal from the main board, or the inverter boards have shorted circuits that cause the 12v/24v power supply to be in the safety shutdown mode.

This can be due to possible AC factors in the power supply and is due to poor regulation. So check for faulty, leaked or weak capacitors, if the fault clears up on heat then thisis for sure. If so you can simulate heat using a hair dryer to pinpoint the area of fault and confirm. Also placing a capacitor of similar value in parallel to the suspected capacitor will confirm as the fault changes.
Attempt only if equipped.

I do not know how to do a channel scan, can you help me please? I seriously thought that I could find anything online but I have not been able to find how to channel scan this tv.


What brand/model TV do you have? If the TV has several input options, make sure that the TV is set to the TV mode. (Use the Input or Source button on the remote, some TVs have this on the TV as well but not always)

Some can only do a channel scan with the original remote. My old Emerson CRT (~20 years old) launched a channel scan when I pressed the Add and Delete Channel buttons together on the remote. Fortunately even when most of the buttons failed on that remote, the channel scan still launched.

Other TVs from that time frame have an channel scan button in the control panel. Often these are hidden behind a panel to avoid accidental resets.

More modern TVs usually have the scan as part of the menu. Depending on the TV, press Menu on the remote (or if available on the TV (sometimes can be done by pressing Ch+/Ch- together)). Then look for a Setup option or a TV icon. If you have a Setup menu, you will then need to go to the TV submenu. Then find the option for setting the input signal (TV/cable) and then you should be able to launch a channel scan. (Usually the Ch+/Ch- (up/down) and Vol+/Vol- (left/right) buttons will navigate through the menus.)

Unfortunately, without the make and model, I can't give you any more help. Please write back with your brand of TV and I'll check if I have the manual in my stack.

(low end universal remotes do not always include the menu or source button. If your TV doesn't have them, you may need a different remote. The ones that can be programmed via a USB connection are the easiest to set up.)

Hi,

You either set the options incorrectly when running the "First Time Setup" or you skipped the first time setup entirely. Even though the cable works with your older TV, you still need to setup your new TV correctly to receive the cable feed.

The quickest way to do this is run the setup manually from the menu as follows:

1. Turn the TV on
2. Press the "MENU" button on the remote
3. Use the DOWN arrow key to highlight "SETUP" (the arrows are the big ring button around "OK")
4. Press "OK" to enter the SETUP MENU
5. Use the DOWN arrow key to highlight "PROGRAM CHANNEL"
6. Press "OK" to enter the PROGRAM CHANNEL MENU
7. Use the LEFT/RIGHT arrow key to ensure "CABLE" is highlighted
9. Use the DOWN arrow key to highlight "AUTO"
10. Press "OK" to enter the AUTO SCAN MENU
11. Highlight "ALL CHANNELS" using the UP/DOWN arrows
12. Press "OK" to start the AUTO SCAN

The scan may take several minutes to complete.

13. Highlight "APPLY" using the the LEFT/RIGHT arrow keys.
14. Press "OK" - all of the scanned channels will now be saved.

The TV should now return to viewing mode and you should be able to watch cable on your new TV. If the TV does not automatically exit the menu, simply press the "EXIT" key on the remote, next to the MENU button.

Please run through the above steps and if you are still unable to get the cable channels on your new TV, please post back for further assistance.

Regards,
BElectric

Can't change channel using the remote or buttons on tv


Simple Fix

I had the same problem, couldn't change the channels with the remote or on the side of the TV. This was for a Vizio 37"

Here is the fix:

1. Turn on TV

2. With remote, press the Menu Button

3. Go to Antenna Menu

4. Select Auto Search
Let it search, it could take several minutes. It may not finish to 100%, mine got stuck at 79% for 10 minutes. It's fine if that happens, go ahead and cancel.

5. It should be done, your remote will work perfect along with the TV channel buttons.

Channel buttons (up/down arrows)


Do an autosearch in the setup menu and that should program those buttons. Weird I know, but it worked for ours!
