The beeping noise is usually related to the Horizontal out put transistor or flyback being faulty or one of the coils are loose near the flyback. If you remove the rear cover without touching anything can you tell if the beeping is coming from the large transformer with the red wire coming out of the top or is it coming from a black transistor on a aluminum heat sink.
