    Plasma ooops...

    I got the LG plasma working and the image looked good. Unfortunately I wanted to adjust one of the voltage pots (black level) on the ysus without taking the back off.

    The screwdriver touched the case and the fuses went on both y and zsus.

    After replacing those and feeling mighty stupid I powered the screen on. At first it showed a really messed up image. It looked like windows in 8 bit color. Slowly the image faded away and now there is nothing. No OSD either.

    All the voltages are normal, the red LEDs light up on back, no protect mode. On the LVDS, one green led blinks and one stays lit. The rest only turn on at start-up.

    Any ideas.

    Next time use a plastic 'diddle stick'.

      Found a dead smd fuse on the video board. I fixed it but still no go. It is off a 2.5v regulator (which works). Would replacing the board fix this?

        OUCH.

        Always use a plastic tweaking tool.

          Ordered a new video board. Hope it works. It was only $30 bux. I got to use this screen for like 30 minutes before I adjusted it. What a downer.

            The IC whose fuse blew was the LGDT4410 IEC.
