the symptoms you relate of have audio but no video - or that it comes on late, and gets longer as time goes by, is related most often to failure of the high voltage system. The repair nearly always revolves around the flyback transformer and/or the horizontal deflection amplifier (the horizontal output transistor, for example).
The best repair method is to replace both the flyback and the horizontal output transistor because if only one is replaced it is common for the other to fail soon thereafter.
It takes a couple of hours of labor for a tech if he has some electronics repair experience; longer if not
Call a technician to fix it for you if you can't do it yourself.
