It doesn't turn on and the standby LED doesn't turn on either. | Power supply board with all voltages and when disconnecting the cable that connects the power supply board to the main one, the display LEDs light up. | The defect is in the power supply. (cm807) replace the same 47x50 volts. | eletronica cachoeira |

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 |
