Sorry Jim, I have long forgotten the exact location of the bad solder
connections. However, I will say this, any good tech with the aid of a
simple "magnifying hat" would easily find the bad solder connections by
simply taking his/her time and carefully going over the main PCB board (The
PC board that has the flyback on it). It was not to hard to find, but you do
have to look over the board as you would any board to find all the (CSJ's)
Cold solder connections. This note on this problem, after replacing the HV
Trippler, will solve this flashing on/off pic.
