Digitor tv model G-7200 pcb 031B The tv does not start; there is 10.47 volt on the collector of the HOT (BU407)whch is straight from the FBT and there isn't any volts on the base. Checking the circuit board I see the base is connected via a resistor to ground and via a high voltage ceramic cap back to the emmiter line of the HOT. That is it. Shouldn't somethingelse be feeding the base or do these 12 volt tvs work differently? Any thoughts will be very much appreciated. A.T.
