TV didn't turn on. I found capacitor c513 exhausted. I changed the TV, it turned on but with a reduced picture despite normal power supplys. | The problem was the faulty ic501 (la7837). I changed it and the TV started working normally again. | Carlão | |

Relays would knock and only turn on the relays for 1 second. Tsound was no voltage in the high voltage transformer. | Key malfunctioning. | A key was malfunctioning. When I replaced the key I noticed that error 1 appeared on the display. This led to the conclusion that the wiring was reversed in the relays. I spoke to the customer and he said he opened the microwave and touched it inside. I wired it correctly and the relays continued to knock. I tested the microwave (see a pdf of the microwave) and verified that the relays were reversed, that is, the wiring for relay 1 should be for the grill and the other for the magnetron. After changing the wiring it started working properly again. | Microondas |

+b of 110 volts and other power supplys are pulsing and the TV does not turn on, it appears that tsound is a short in the horizontal output. | The defect was that r801 in the power supply primary was altered, with its value being 28k and changed to 68k. It was just a matter of changing it and the TV stabilized all the power supplys.... | Antonino Matos | |

It turns on and makes a noise as if it were flayback and then turns off, a symptom of horizontal synchronism. | Check for possible cold welding on the horizontal driver transformer. | I cold welded it and it fixed it, good luck. | Eronaldo (erontec) |
