Harry;
A friend in a neighbor city fixed one with similar 4 times pulsing and
not starting. He labored with it for a week or two replacing many components.
I found some tips in Repairworld that led him to cracked legs on main board
around PIP module. It was related to a 3.3v supply?

Chassis: CTC203A
Symptom: NOT STARTING. Relay cycles 4 times then off
Cure: resolder U18101 and area near top of PIP module
TELEVISION RCA CTC203 Trys to start, High voltage only comes up to about
5K volts Unsolder pin 10 of T14401 if sound comes on and stays replace flyback
t14401
TELEVISION RCA CTC203 NO START vert i.c. faulty (unsolder & set starts)
TELEVISION RCA CTC 203AX will not start tries 3 times F2PIP board quick
check pull board if defective set will now sart
TELEVISION RCA CTC203 No startup , pulses 3 times , dead Suspect F2PIP
board , U18101 3.3 v , check solder on devider resistors
TELEVISION RCA CTC203 Starts fine then later shuts down and tries to
restart 3 times and Quits Replace Q14901 in the X-Ray Shutdown Ckt on top of
board
TELEVISION RCA CTC203 WON'T COME ON RELAY CLICKS 3 TIMES CR14704 SCAN
SUPPLY DIODE SHORTED. SET RUNS FINE AFTER REPLACE
TELEVISION RCA CTC203 WON'T TURN ON REPLACE U14104 12 VOLT REGULATOR (ECG
966)]
TELEVISION RCA CTC203 No horiz deflection open R810
TELEVISION RCA CTC203AA5 Won't power on, 5V standby OK, 139V low Leaky
zener CR14117 #244244
TELEVISION rca F3668Yx51 chassis CTC203Ca5 not turn on replace Q14401
TELEVISION RCA CTC203AD5 HIGH VOLTAGE COMES UP THEN SHUTS DOWN MAY CYCLE 5
TIMES REPLACE U14101 OPTO-COUPLER
