Question about Toshiba 27AF45 27" TV
Two of the diodes are shorted, change all four out with higher spec. diodes. will not power up, any suggestions ? thanks
Check the fet Q502 (2SK3326), Ic504 the opto-isolator (PC817), and D517 for leakage. Use a dmm with diode testing - test froward then reverse, if you get any sustained readings both ways replace it with an NTE552. Also check R510 100 ohm....
