Was using ps4 on Vizio D-Series, then tv says no signal, I turned the tv off, and now it will not come back on at all (tv only 1 yr old, do not use tv often)

Mybe the sleep timer is on? check and make sure that is turned off

SOURCE: when i turn on y Vizio LCD TV theres a blue screen that says no

Your TV is probably in RGB mode which means its looking for a computer signal. Plug a computer into your TV and then it will stay on. Then you can change it back to TV mode.

My vizio recently did the same exact thing. Vizio sent an HDTV tech out to fix it and it was the power board. He put a new board in (took 15 min) and the tv works like new.

U have a front screen panel LED light indication are flashing or totally dead,no LED light indication at all?Yes,than the tv power supply board is the causes and the problems.That the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish tv power supply board for the replacement.

Most probably the mainboard of the TV has a problem. But no worries as it is only 6 months old call up Vizio and they'll replace it for you free of charge :)
