    When you say reset do you mean just unplug and plug back in?

  • mets23 Mar 05, 2008

    I think you meen just unplug and replug back in. I have the cover off the back of tv I see 4 diffferent circuit boards I dont know which one is the main board. A Picture would probably help. Sorry I fix appliances all day, but not tvs. Thanks

Reseat the the LVDS cable inside the set. this is the cable that connects the main board to the panel. if that does not work replace the LVDS cable and the main board.

    the main board is the board that looks like a computer board. it also has the inputs on it (tuner, video connections, ect..). there is a wire connector that has multiple wires on it and has a ferite core around it on both ends. this is the LVDS cable and yes when I say reseat it means unplug it and plug it and replug it. the LVDS cable goes to the top portion of the panel board.

    in repairing any LCD tv you must know the components so here you go.

    main board the computer looking one. this produces the digital portion of the info to the panel.

    power supply the one with the transformers on it it produces 24 volts, 5 volts, 12 volts (and other voltages) to the panel and the main board .

    the Tcon board this is the board not visable and is part of the upper panel. this is the "painter" for the panel it takes info from the main board to produce the picture thru the LVDS cable. this board is not available for replacement and is part of the panel.

    the inverter board also part of the panel and generaly not repalced (however some manufactures are now providing them as a replacement board), this board lights the back lamps.

    I hope armed with this info you can detumine the problem at least board level. start with the LVDS cable.
