This is a common problem with Vizio TVs. The problem is usually caused by the tv's firmware. You can try updating the firmware, but if that doesn't work, you'll need to contact Vizio customer support.

Throw the universal remote and get a factory one, no one uses universal remotes anymore

It's actually the panel that's bad, not the board, one of your clock lines are shorted but it can be fixed with a piece of scotch tape by masking off the correct clock line, there should be 8 of them and it will give a decent picture just using 7, there are some youtube vids that describe how to find the pin to block if you want to dig into it.

Have you tested power supply voltages, that would be a great place to start, should have been done before throwing boards at it verses just guess what's wrong. Look at the legend on the power supply, start by testing the 5 volt supply, if that's missing the set will be totally dead

Are you able to get the back off and take some voltage readings?

Take it in for repair. There are boards that run the display. The main board does the content. https://www.fixya.com/support/r29790007-repairing_own_television ..

Hi, I would have attempted a system software update first once the screen went black. I would also disconnect all accessories. Then, if still failing, I would schedule a repair with a tv repair shop because it's dangerous to deal with internal portions of the tv as a consumer. Thank you.

Replace the power board

Hell0, have you tried using a different HDMI input and HDMI cable? If you do and still have the same issue, it may be the eeprom on the main board going bad. Try doing a software update, some updates rewrite the eeprom and it may take care of this issue, otherwise the main board will need to be replaced. Thanks Techman 57

Hi, please double check that you haven't' "muted" the display or accidentally switched to a different HDMI input. Fuse might be near the power supply board. Thank you.

Use the left and right audio out from the TV

Hi, First please press the "menu" button to check if the menu item appears on the screen. If so, the device that's connected to your issue has the problem and not your vizio. You should then focus on that device. If not, please hold the "mute" button down for 5 seconds because your screen could be "muted" (ie turned off). Some vizio tvs have ability to mute a screen. Otherwise, you'll need to call vizio to ask about potential repair via this phone number 1 (844) 254-8087. Thank you.

You have a bad panel, time for a new TV

Hi, Please remove all extra devices (ie video game console, dvd platyer) and turn on your tv again. If not working, please attempt to change channels on your remote or remotes. If still not working, please setup the tv like you did when you first bought it. Thank you.

Hi, Please ask Vizio to email you the driver so that your device can regain touch-screen capabilities. This is their phone number: 1 (844) 254-8087. Thank you.

try unplugging it and removing batteries from remote then replace batteries try reset on back lower left

It would need to be a 3d TV, most sets aren't 3d compatible and none have been made since 2018.

Unfortunately sound like that's going to be the screen itself usually it's not cost effective to replace the screen

Model?
