Question about Toshiba 3387DB TV
Horizontal Hum bars drifting vertically through the picture. Worse on the UHF input much less apparent on the SCART input
It is due to 60Hz HUM IN POWER SUPPLY. please check for input supply. also check for mains filter capacitor in tv. also check for one diode open in rectifier ckt.
