The tv have a dead part call the FBT-Flyback transformer,a big black block of plastice with a red wire with a black cap hook it to the CRT-(Tv picture tube).The FBT-give the tv highvoltages to the CRT(Tv picture tube).This tv is old model of an analog tv probally can't find part for it anymore.
Verify service number from back of set................. Probable bad IHVT ( aka flyback transformer) and possible shorted horizontal output transistor........T.
Please let me know if # is F36650 YX01.............
Confirm service # from back of set = F36650 YX01.......... Transformer red HV lead attaches to CRT & Horiz output xistor is on heatsink next to transformer = 2SC5148 ......... Rca part # 257805 or ASTI 2078 and 237470 xistor............ Do not use a generic transistor = name brand only............T.
Apparently, a power supply weakness re-occurring........ Possible incomplete or incorrect repair the first time..... Have it diagnosed by a qualified RCA tech...... Always a possibility = IHVT = 257805 or asti 2078.......T.
Please rate this solution..........................
