This set switches on briefly (less than 1 sec) with EHT, then off again and rapidly flashes red LED on front till switched of at mains. Replaced the video processor tda 8844, wich was 12 ohm to ground on pin 47.also replaced vertical ic tda7845 wich had a big hole in it! The set still has same symptom as before. Pin 50 on the tda 8844 is over-voltage protection and reads about 2.1 VDC when the fault is present but as i am without a diagam i dont know if this pin will go hi or low with overvoltage. HELP!
