Normal sound comes out afterwards | Check if you have the 48v and check the 12v | If you have these two normal voltages, changing the thermal paste is resolved. | Protec Eletronica |

White image | Power supply at vcom was low, 6v | As I didn't have the schematic for this board, I isolated the power supply paths from the flat that goes to the TCOM, soldered a wire to the VCOM fuse (screen board) and removed 12V directly from the power supply. it worked perfect. | TECNARDI |

Image only in the middle of the screen. like a strip of light in the middle of the screen with a normal image and the sides, everything is dark! | Burned out led bars. | Replace the LED bars for identical ones. replace resistors r9201 and 9101 with this value (4r7 x 2w). Replace or sand the light diffuser acrylic as this TV model burns out the LED and also the acrylic. | EvandoViana |

When plugged into the socket, the LED comes on and turns off as if it were about to start, the relay hits and the TV doesn't turn on; o +b normal 115v | 9v regulator voltage (ic804) oscillating. I found c850 shorted. | I just went to replace it and the TV turned on | J.S ELETRONICA (Nilsinho Rodrigues) |

Turns on, appears immediately, disappears image and is stuck on the green LED, does not respond to any command. | I measured the LED bars and they were altered, I replaced them and the problem persisted. | If changing the bars does not solve the problem, check all the 1r0 resistors in the driver region, in my case tsound was 1 open, this caused protection even though the bars are new, if tsound are none open and the bars are guaranteed to work, replace the driver which solves the problem. . | Kelvin |
