RCA N/A CTC187 PICTURE GOES BLACK AFTER A 1/2 HOUR - OSD/AUDIO IS NORMAL CHECK/REPLACE U2903 (7805 REGULATOR)
RCA N/A CTC187 NO HORZ. SWEEP - ONLY HAS ONE VERTICAL LINE CHECK/REPLACE C4403 (PART NUMBER VARIES DEPENDING ON CRT)
RCA F31672 CTC187 MISSING ONE OF THE PRIMARY COLOR - RED,BLUE OR GREEN CHECK/REPLACE IC1001 (P/N# 215524)
RCA F32632 CTC187 AGC OVERLOAD - PIN #12 OF U1001 STAYS AT 8 VOLTS - WHEN 'IF' IS INJECTED AT PIN #1 OF U7301 , THEN NORMAL PICTURE CHECK/REPLACE U7301 (P/N# 215532)

RCA F27672 CTC187 PICTURE BOWED ON THE SIDES AND NARROW WIDTH DURING CHANNEL CHANGE CHECK/REPLACE C4407 (P/N# 214754)
RCA Chassis:ctc187cl3 Problem:intermittently would not tune cable channels below 51 Solution:L7109 in tuner was intermittently open. 3.9uh pn 200559
RCA F27641BC Chassis:CTC187AB Problem:No pic. No snd. No brightness. HV OK. Solution: CR4704 (207878 Diode Kit); R4702 (3.3 ohm 2w); R4517 (24 ohm 1w) Comments:Could hear high voltage come up at turn on. R4702 & R4517 burned open. CR4704 shorted. Must use RCA 207878 special high temp diode. NTE sub will not stay!
RCA Chassis:RCA (Sears) CTC187CK Vertical is rolling (menu does not roll) Repalced IC1001, T-chip (LA7610) Comments:Even though the vertical sync signal at pin 17 of U1001 was correct amplitude and frequency (according to Sams), a new IC repaired the problem.
RCA CTC 187BD2 Sides bowed in. Pincushion problem. CR4403 and C4407 fixed the bow.
GE 27GT618 CTC187BD2 Dead CR4106 (140V supply to HOT) part# 164589/PFR856 R4110 (R110U, 33K ohm1W) C4107(100 mfd@250VIC U4101 (STK730-010)) Comments:Main v. regulator IC U4101 (STK730-010) should have a negative 40 volts at pin 1 (pin 3 hot ground as reference) if working. Zero volts. Bad U4101. Final fix,replace U4101
RCA ctc187ck This set would very very breifly pulse up on HOT collector at plug in, and B+ was on collector, thereafter there was no activity evident from micro or anywhere when pwr button was pressed. U3201 part #223954 was bad.
RCA PS27108 CTC187BF2 NO VHF CHANNELS LOW OR HIGH BAND UHF CHANNELS OK REPLACED U7301 215532 Comments:THINK THIS APPLYS TO ANY RCA / GE CHASSIS WITH TUNER ON BOARD
RCA Chassis:ctc187 Narrow on sides, width and height vary with scene change Replace c4407 and cr4403. (will test good)
GE 31GT660 CTC187CH6 No Start Up, Fuse OK. Main Cap. Shorted. C4007 200 volt X 680Mfd. Also CR4002 just off C4007 leg needed resoldering.
RCA F31672ET Chassis:CTC187CL2 Dead- power supply squeels H.O.T. Q4401 = BUH517 + bad connection L401 (cause of HOT failure)
RCA Chassis:ctc187 eeprom replacment build a double eeprom socket Comments:To shorten eeprom replacement time, build an eeprom fixture. You need 2ea 8-pin sockets, 1 dpdt switch, 1 small bread board, 4-pin header, and some wire. Conect it so that the switch switches the clock and data lines(pins 5&6).Pin 8 is +5 and gnd pins1,2,3,4,&7. How this helps is if you have a bad eeprom install old and new eeproms in sockets conect in place of eeprom on chassis, start set with new eeprom, swith to old eeprom and look to see if tuner data is salvagable and wright it down, switch to new eeprom adjust values, turn set off and install new eeprom on chassis.
RCA F32672SB Chassis:CTC187CL3 Rattling and arcing noise when power is pressed. Resolder FB402 and CR4403 at location T-11
