Hello, and sorry you're having problems. We are now connected on this website- which saves you money over having a Tech come to your home, and in many cases we can fix the problem you're having. In other cases, these things do require additional parts to fix. But I can help you with that as well.

Offhand these symptoms point directly to a Power Supply Board, or T-Con (LCD controller) board failure. The power supply produces several voltages- so it can still operate even when the one that drives the T-Con is out of spec. The average cost for a shop to repair this is between $200-$275 parts and labor.

Alternatively, on a DIY level- knowing whether the T-Con or Power Board are the culprits, requires testing the power supply using a multi-meter inside the TV. You would need to have some experience measuring live voltages within electronics to diagnose this. If you choose to go this route- let me know and I can help you.

Or, the Layman's DIY approach is to purchase both the power supply board and the T-Con and replace one at a time until the picture is restored. Average cost for these parts are in the $125-$150 range- total.

However finding those parts- or seeing IF they are even available requires the full model number on the sticker on the back of the TV (the serial number does not help us here). A Vizio model number would be something like:

E422AR or similar.

Other than what's posted above- there isn't a "pushbutton" fix for this problem and it does require component replacement to fix the issue.
