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! | Burnt out LED bars and high current in the LED power supply. | After changing the LED bars, replace the r9201 and 9101 resistors with 4r7 x 2w resistors and sand the light-diffusing acrylic. | Samuel Silva |

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 |

TV works normally, turns off and shows blue, green and red colors with no image | The 202 ci e1 was replaced with no solution, returning the same defect, so I put a cooler on top of the processor and the result was nothing but the problem. | Defective pci card but it was mine and it was perfect until today, ok, sound's the solution for anyone who has one of these, ok, good luck and good service to everyone | eletronica publison natal rgn |

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 |
