    the tv will power back on (all the lights for touchscreen buttons and VIZIO emblem lights up), but is won't turn off, change channel, volumes won't work, source button doesn't work etc. If i want to turn it off i have to unplug it.

Change the main board if you have good picture and sound. If you don't have picture and sound, the inverter will also need to be change.

Could be the power supply gone bad.
No easy solution I'm afraid.

Vizio tv first screen had bluish discoloration and than few days later a pop and screen went black .ANY IDEA OR SUGGESTION all of the sudden started experiencing severe discoloration


This is called the pop of death! If you call vizio they will ask you if you heard a pop, this is a common issue and unless your under warrenty your looking at 916$ to fix it. (assuming you have no sound! If you do its 430$ plus tax for parts and repair. You can buy a used one on ebay for that price!

I have the parts numbers if you want them!
Call vizio if you have had this system for under a yr the will fix it free!

As for me my 50 and 42 inch had this issue and well I am out of warrenty.. I hate vizio lol!
