        a CTC197ce2 chassis clicks three times then stops Tryed L401 cleaning same thing noticed rt4305 burned.. Ned value and if fly is bad???
        • ctc197curt., Sat Apr 8 9:33am
          On your ctc197 the value of the r14305 is 3.6k and most likely the flyback is shorted.

        Model F32685 TV had no vertical delection. Check for bad solder connections at the flyback transformer.

            you have bad filter off boster voltoge 33 mfd or 47 mfd 250 volts or higer
          • CTC 203 jail barsDani, Wed Apr 2 9:22am
            If you use a generic flyback, this will sometimes cause this problem. Try an ASTI, or HR flyback. Dani
          • Re: ctc203Anonymous, Wed Apr 2 9:01am
            Could find nothing on jail bars on that chassis, could be the flyback if it was not an oem and the bars were not their before replacement.
          • Jail barsJames P Daly, Wed Apr 2 1:30am
            Sure sounds like you have a bad electrolytic in boost supply. Look for a cap with value between 1mf and 10mf at 160-450volt. Should be somewhere around flyback or on CRT module.
