    Samsung LN46A530 image issue when power on

    Hi,

    I have a Samsung LN46A530 TV with an issue at power on. At first, the TV was powering on/off and clicking. I change 3 bad caps on the PSU and the issue was fix.

    But, at power on a part of the screen is very dark and change progressively to be OK after 3 to 10 sec. I checked the connection at the t-con board and all seem to be ok.

    Is someone have any idea of the source of the problem?

      I don't think the problem come from the backlight.

      With a video it will be easier

        Panel is bad on that side, the side tabs voltage need to be isolated with tape cut-off method or they need to be removed if possible.
