Question about RCA Televison & Video
SOURCE: blue screen
It sounds like the Blue drive transistor is shorted out leaving the blue color gun on full blast which is drowning out the other colors. If this is the case the transistor needs to be replaced. A qualified technitian could easily replace this part.

Other than checking all the connections going to it for signal it is likely a shop repair.
The nature of these sets is someone must open and inspect them and check for voltages missing.
At that point it becomes a guessing game---try the boards (purchase them) and see if a bad board.
It is always possible the front screen unit or display has failed which is fatal cost wise.
You have to weigh the cost of repair, age of set and cost of replacement in this.
The only way anyone can KNOW which board is bad is to actually remove and replace it----most shops look at it and shoot you a high estimate.
let me know if you have questions.
