Maybe not. Those CTC187 flybacks hold up much better than the newer RCA's; but, I'll bet the HOT or the diode in the 140 volt supply is shorted. Usually, when the diode shorts, it takes out that STK regulator IC; but, this could be an exception. If the HOT is bad, check those blue caps around the HOT. Even if the flyback is bad, you should be able to get one reasonable.
