    so what symptoms do you get when you first turn on the tv
    from standbymode the TV turns on (whit the samsung on sound) and i can see my "tuners" sorce chanel 1 for 1 sec'... the tv then turns off (whit the smasung off sound)

    further testing leads to checking for bad caps and testing power pins out to the motherboard all tested fine...
    disconecting the motherboard from the powerboard and swiching the TV on got me the same resolts as it turns on for a second and then turns off...
    further testing the in and out of the power invertors turned out to be fine.

      possibly a bad ccfl tube or connector but too look at these requires a screen strip down and high risk of cracking the lcd panel etc hopefully budm will have a idea what too check next

        "from standbymode the TV turns on (whit the samsung on sound) and i can see my "tuners" sorce chanel 1 for 1 sec'... the tv then turns off (whit the smasung off sound)" That means PS-ON must have gone low.
        So you need to report the DCV reading of all the pins of the power supply board that goes to the main board.

          A common fault when the TV turns on and shuts down is the control pad is faulty. The touch buttons can go bad. I believe it's possible to disconnect the touch pad bit and use the IR remote only as they are on separate PCBs.
          Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

                Did anyone ever get anywhere with this fault? I've just got one in with the same problem.
