Will not turn on

I replaced the Flyback and Horizontal Output X-Tor, No change. I could hear the power supply come up when I plugged it in, B+ was present and I had Horizontal pulses on the base of the Horizontal Output X-Tor. I was look through some RCA bulletins and came across TV-03007. Basically it says that CP23 a 2.2uF 50 VDC Cap would cause the set to start intermittently or very slowly. As per the bulletin I replaced this cap with a 4.7uF 50 VDC Cap. That was it! it came right up and has been working ever since. This also pertains to chassis' "AA1, BA1, CA1 and CB1". Good luck, I hope this helps.

• Many TVs actually run their switchmode power supplies even when off to power the standby stuff like the remote control receiver, real time clock or timer, and channel memory. Depending on the design of the regulator, the power supply may be running at a low chopper frequency due to the light load. Some people, dogs, and rodents are then annoyed. It could also be an indication of a fault like a bad capacitor or loosened transformer core. I hope this help!!!
