        Replaced AS-19HG with exact new replacement.
        Problem persisted, everything is as was.
        Looks like MB issue after all...

        Any chips worth replacing there?

          have you re tested the gamma voltages what are the readings now? and some people are saying that the new chips can be faulty so have to re fit with another one.

            Haven't retested voltages yet. Will do.
            And I have another new chip, so I can replace this, but it just seems not likely to me that,
            a) new is faulty, (I opened them from factory package)
            b) fault is precisely same, nothing differs from the old one.

            Furthermore, I welded it on with solder iron only, as large pad underneath was not welded originally, just legs. So no overheating of chip definitely.
            stay classy

              Samsung monitor Installed 1 cap wrong, now menu button dead, "no signal detected" msg
              by glutton4punishment
              Samsung synchmaster 226BW.

              Before I replaced 5 caps, the screen was dim.
              Sometimes it wouldn't turn on.

              I opened it up, and found 4 bad caps in the pwr supply section.

              I unfortunately installee one backwards, i.e. wrong polarity.

              When I turned it on, I head a loud pop, and I quickly shut it off.

              The replaced caps are 3 860uF 25V's, and 1 330u 35V.
              One of the 860uF blew.

              I didn't have another 860uF at home, so I tried it with a 1000uF 35V cap (I remember the reading of the 1k uF cap was close...
