T-con and inverter boards are not related to this problem so you might as well return them for a refund. When you try to power it on what is the status of the LED at the front ? Does it remain in standby mode or does it turn on but does not respond to any command?

It could either be the T-con(AKA LCD controller) or its the LCD panel. It cannot be anything else. So you should give the T-con a try and chances are it can fix the set.

SOURCE: My Vizio 55XVT1A power on, has sound, but no picture. I changed new power board, main board, T-cond board, but it still same problem. What's wrong with it? Is it anything with inverter board? Than
If this is an LCD tv the backlight inverter is bad, a good way to check it is to shine a flashlight close to the screen and see if you can see a faint picture.
Let me know what you find
