Toshiba 3377DB excess red in picture

[shekharmahmud]

All the pictures are red. Other colors are ok apart from red. Too much red color on the picture. I was trying to make the color to 0 position, but steel makes no difference. Could any one help me what is this could be?

Many thanks

You have a bad Driver in the Crt Board, there are 3 transistors in that small board in the neck of the pic tube, check them all, also the 3 big resistors in there, and the electrolitic cap.
