Question about Vizio VL Televison & Video
Lost red... have blue and green... is there a fix, or purchase a new one?
NO red should be fixable but base decision on age of set and cost to repair---if loss of red (total) I would suspect main signal board that processes all information to the screen for the picture.

THe most likely cause for this problem is bad connection of the cable connecting the main TV board with the LCD controller. It's called LVDS cable and is hard to miss, usually fat round and black, connecting a board from the chasis with a little board in the top center of the LCD assembly.
I'd open the TV and gently try and reattach the cable to see if that yields any results. You can try it a few times, in fact I'd do it while the TV is open and working so I can better see if adjusting it makes a difference.
There's also a chance that the LCD logic itself got burned and misses on one of the colors. But I don't remember ever seeing that.

It sounds like you have a driver board problem. I suggest getting in touch with Toshiba and see if they will have it diagnosed/repaired under warranty. If not, they can give you the name and number of an authorized repair center who will know best how to diagnose and repair the problem with those units.
