    Pulsating Half Vertical line on edge of Acer AL2416W

    Hi all,

    I have an Acer AL2416W that I just recapped. However, after finishing and putting everything back together, I just noticed that there is a vertical line on the right edge that goes about half way down the screen. It does not look like the typical vertical line -- it has somewhat of a pulsating glow to it. Has anybody seen anything like this before?

    Try reseating and cleaning all your connections to every board.

      OK, I actually have a second AL2416W that I recapped earlier, and I replaced every board except the one on the panel itself, and the problem still remains. I also tried disconnecting and reconnecting the small board on the panel (tcon?) but no avail.

      I guess this means that the panel itself is bad? Does anybody have any experience with fixing this type of problem?

        Just in case anybody else has this display, here are the components that I had to replace on the TDK inverter board:

        Q6: was P5504EDC, replaced with FDD6685 (Digikey part # FDD6685CT-ND)
        Q4: was P2804BDG, replaced with FDD6690A (Digikey part # FDD6690ACT-ND)
        Fuse near Q4 & Q6: 1.25A 63V Fast Acting (Digikey part # SF-1206F125-2CT-ND)
        10X 100uF 35V Cap: United Chemi-Con LXZ Series (replace them all; Digikey part # 565-1979-ND)
