Question about RCA 20F511T TV
Hi, My tv has a bright green tint to it all of a sudden. Does anyone know what the problem might be? It's fairly new also.
Could be one of a few things. There are transistors on the CRT board (board at the back of the picture tube) which control the intensity of each gun (red, green, blue). The most likely thing is not too much green in your case, it's probably the absence of one of the other colors. Likely you won't see any red or blue in the picture.
One other thing could be a blocked electron gun (inside the picture tube) in which case get yourself a new TV, there's no cheap way to fix that, in fact, you can't even buy replacement tubes for most sets 'cause they're just not cost effective.
Another scenario is a faulty processor IC not giving the correct signals to the CRT board for proper color balance.
All of the above would require some electronics skill to troubleshoot. If you don't have any, don't even open the back, there's likely nothing you can do and you put yourself in danger if you don't know what you're doing.

Is there a color button on your T.V? Maybe someone bumped it. You know, like on the old Macs. I know your tv is new, but there might be a button. check.
