This sound would turn on, and then return to standby mode, then I saw that one of the audio output MOSFETs had a short circuit, so I replaced it, and it stopped turning off. But I noticed that the l803 coil was getting very hot, to the point wsound smoke was coming out, so I removed all the wire from it, replaced it with a new one, and it still had the same defect. The solution I found was to replace it with one of these, which is on the horizontal tube TV circuit. and I also replaced the r818, 10r. and the problem is over. | Replacement of coil l803 and r818 and also one of the power supply MOSFETs in short position q806. fqpf16n15 | MARCONES DE ARARIPINA-PE | |
