It sounds more like a shut down circuit problem if you can feel static from the face of the picture tube after it tries to start up. There are several things that can trigger a shut down condition on TV's. For instance, if there is no vertical deflection signal present, the set may shutdown to prevent a permanent line being burnt across the front of the tube. If the power supply wasn't regulating the B+ voltage properly, it would shutdown to prevent damage in the horizontal sweep section. Or if the horizontal deflection circuit was defective and allowing the high voltage to climb too high (say above 33,000 volts) then the sensing circuit would trigger a shutdown event. If any of the above sounds like gibberish to you then you will need to take the set to a professional for repair.
Your problem sounds like what our RCA does once in a while. The service tech actually suggested we unplug it for a while and plug it back in. I thought he was crazy myself, but it worked with our TV. Henlopen sounds as if he knows a lot more about it though.

Hi, It seems problem with low screen voltage to three picture tubes in this rear projection tv. If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue. Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you. Thanks.
The clicking you here is the mosfet trying to turn on power on the the oscillator then power to the tranformer. The thing with red wire come from the top to a anode splitter. The question is where the power stops. You know it is going to the mosefets but is the trasformer powering the tubs. Email me for anymore questions [email protected]
