If this has the original flyback and never had a cap kit and you do the cap kit normally the flyback goes out sooner then later. Also, the tube could probably use a rejuve. Like i said if the flyback is the problem and is weak and the cap kit is done and everything goes back to the proper voltages the flyback might pop and release a fine smell that last for days( it might take a few minutes to weeks). I always replace the flyback if it is original and the HOT so i dont here from the customer or service man again on the chassis.
