Snapping sound from Kine or from HV circuit?? That should give you a clue
as to what may have to be addressed.

I have a RCA tv with the chasis number of CTC189BG5. Turn on when its cold
and picture looks great. About an hour later you here a snapping sound and
picture goes bright with retrace lines. Adjust focus and brightness on
flyback and nothing changes. Any suggestions on how to fix?
