    Thanks for reply, I replace the T-con board, it still have the same problem, there are 2 other board ( the main board where the input connector are) and FRC board, which one can also cause the picture to go diagonal. I also notice when the tv is not receiving any signal.
    It would stay normal with the word no signal in the middle or the screen.

    The main board sends picture signals to the T-con board, so look into that one. Power supply wouldn't cause that.

    On this tv, the main board is connected to the FRC board than to the t-con, what is the function of the FRC board, can the FRC board cause the picture to go diagonal if the main board is good.

    Thats the frame rate control. It's function is to make colors better. I would ask the smart guys at www.shopjimmy.com if that board affects the picture that way.
