1. have you tried what i suggested?

2. were you rough on the CRT neck board?

3. Tap or wiggle the crt knock board while its on and see if there is any color fluctuation, that will be tell tale of any broke solder joints from rough handeling.

weren't you the same guy that cut the HV wire going to the tube instead of removing the suction cup?

and you were just going to splice the wire or something?
