Only in standby, the TV does not oscillate - tsound is no 10.5 volts on the capacitor c825=22oomf-16volts, tsound was only 6 volts. | It was the defective strw6753, I changed it and went for it. | ELETRÔNICA MELO BOA VIAGEM -CEARA | |

|
Turned on but turned off again | After changing the power supply for a new one, I started tuning the respective TV, but the power supply went down, I turned the TV off again, but nothing, I disconnected the ysus plug, I measured it and the voltage values were correct, I turned it back on, I measured the voltages on the plug and nothing. I disconnected the 60v plug and the TV started working but with no image resulting in a short circuit in the panel plug (horizontal part). | ||

It turns on normally, but then the sound disappears or turns off. | The components were removed from the power supply and the r128 was changed from 10 to 22k, but it continued so I decided to resolder the IC801 on the logic board, I resoldered it with an iron and solder, with the air station it didn't look good, new solder has to be melted. Resolder the other ICs too. | joaomvjr | |
