24.67.253.203 (XFF: 24.70.88.106)

RCA PS36130 CTC179
Unit will not power up. Unit will cycle on and off 3 times then shut off. Secondaries will not go up.
Found a shorted CR4115 causing the supply to go into over current shutdown.

RCA CTC178
Unit has no audio. Unit lost the audio when a power surge caused TV to shut off.
Replace epprom

RCA G32750 CTC179
Unit has no audio.
epprom

RCA G35931 CTC179
Dead. C4406 blew up.
This is caused by an open C4407.

RCA CTC179
Unit will not turn on after the tuner circuitry was resoldered.
An open existed between U3103(2) to U501 (5). This line communicated the data from the expansion chip to the PLL chip. A jumper was created to replace the open trace to reconnect these points.

RCA PS36161 CTC179
Unit has insufficient horizontal sweep.
Found the peremiter # (horizontal size) was at 15. The nominal position is 20 to 22. Moving this adjustment to 21 corrected the fault

RCA PS35660 CTC178
Intermittent sound and raster
There is a bulletin TV97-005 which lays out a problem with CR3104 a 13 volt zenor diode that has caused this failure. Need to replace this diode.

RCA P46734 CTC178
No Raster. Has High voltage and no OSD.
Screen voltage only 178 vdc With all CRT's disconnected the G2 voltage still is too low.
Unit has defective Focus / screen block.

RCA CTC179
PIP picture drifts all over the band. Will not stay on channel.
Resoldered poor connections on Tuner shield ground pins.

RCA CTC179
first the raster was bright Now it no green.
Replace Q2F, CRF, CR5F, C7F

RCA CTC179
unit looses raster after 20 minute.. Unit does not loose sound or OSD.
Replace U3101 & U3102

RCA CTC179 Shut down CTC179DJ
Unit shutting down as soon as the set is turned on.
Unit needed Focus/screen block.

RCA CTC179
Unit going into shut down when pressing on CPU the set will shut off. Error codes are #17 (Hung Bus). This mean a bus line is being held at either 5 volts or ground intermittently.
the tuner shield was removed to uncover a cracked connection on the center ground post.

RCA CTC179
tuner problem. Has poor gain and noisey. Soldered tuner but the tuner still has a problem. Unit will play then fail with white noise and all snow display. The tuning system, of the PIP tuner works fine
Replace IC501

              • 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.
