You need a circuit diagram. At the micro there may be several power safety inputs and an x-ray input. Monitor those inputs with a scope as you press the power button. The one that does not agree with the voltages on the print will point you to the circuit or group of circuits where the problem is. This is the method I use with all of the Funai product where the power can be turned on and shuts off after a short time. Usually this points to the deflection circuits. The deflection circuit may have 3 or 4 deflection related functions combined into one power safety.
