    Samsung SM2493HM red banding/speckling

    Hi,

    Trying to help a friend sort out a faulty Samsung SM-2493HM.

    The monitor is working but it sometimes exhibits noticeable horizontal red speckled banding and red speckling on dark images? We have tried all the inputs (VGA, DVI and HDMI), different cables, different computer and hooking it up to a PS3 via HDMI but the problem is still there. We sent it back under warranty (a few days before it expired) and had the panel replaced but it's still having the same issue so it looks to be an issue with the internal electronics and not the panel as we thought.

    Has anyone come across this problem or suggestions on how to troubleshoot this issue please?
