It doesn't turn on, but it hits the relay. | If we disconnect the cable that goes from the power supply to the main, the TV turns on and the LEDs light up. then the main board or tcon is completed. | I disconnected the cable from the tcon and the TV turned on, it turns out tcon, but in this case, oddly enough, tsound was bad contact in the flat cable fitting on the tcon, it actually turned off the TV as it moved in this fitting, I cleaned it with propyl isodine and eraser and just ran for a hug. | MIGUELTV |

The blue volume LED keeps flashing and the device does not turn on. the 5v and -21 power supply is oscillating, below what it should be. | After much research, it was found that the 33nf capacitor cb8 was responsible. | Replace for another good one, even if it doesn't show a defect. It is close to the photo coupler and the DVD motor connections. | Romildo Behrend Schwartz |
