MK8500

Lack of electronic schematic | See mk6200 schematic, similar, same output and power supply board, transformer and larger transistors. | Outputs 2sa1943/2sc5200 (mk6200: 2sa1941/2sc5198) to repair this type of amplifier (class AB) and avoid losing outputs, remove the outputs and place a diode in place of an NPN and PNP base/emitter output (or disconnect the collectors ), fix the amplifier/driver circuit (it will give little power, enough to test), only then install the outputs. | R |

Turns on, but does not change CD/USB A/Audio In/Bluetooth/Tuner functions, has sound but does not change volume. the functions also do not change when we choose the other side of the mixed. | Larger flat cable that comes out of the main board and goes to the CD/DVD board, all you had to do was touch it and the equipment started working again. | Remove the flat and clean contacts, but be careful It's the worst device I've repaired to date, to remove the main board It's the "c" that falls out of the ass. | MIGUELTV |

Turns on and off immediately | Defect in the y-sus, after changing the rjp30e2 igbts. The TV turned on and all the voltages appeared but the image was grainy, you couldn't see anything. | After carrying out a new analysis, I checked 3 open resistors, 1 of 51Ω in position r5034, 1 of 100r in position r5019 and 1 of 270r in position r5025, after changing them the image came back perfect. | Luiz Sena Eletrônica HYK |
