GDM-20E20 Problem

    I have a GDM-20E20 with an odd problem. When I first turn it on, the
    screen will stay black for a long time. The OSD does not show up at this
    time. However, I can here it click when the resolution changes (it's
    connected to an SGI Indy), and the green light is on. After a while, the
    picture usually comes up, but that's after a very long while and alot of
    swearing. Is the tube dead/dying? Is there some board/wire that is
    loose/needs to be replaced? Should I make a Sun -> SGI adapter from a
    spare 13w3 extension cable? Did I spend $120USD on a really big and
    heavy paper weight?

    Thanks in advance,

    Can you define "very long while"? I've seen them take a minute or
    two. I just don't know what your patience level is.

  3. I'm running a GDM20-E20 on my PC, and it must be only lightly used,
    because it comes up in seconds, every time, and in all respects it's
    a fantastic monitor.

    For me, a very long while for a monitor to start working is about an hour.

    Sounds unusable to me. Can you hook it up to another host to see if
    you can replicate the problem?

    Right now, no, not really. I have 2 SGI Indys, and the same thing
    happens for both. I've heard from a bunch of people who use the
    GDM-20E20 with SGIs (including Indys with the 8-bit graphic card, like
    mine) without any problems.

  7. You just gave the answer.

    Have a competent technician go through the monitor and resolder any
    questionable solder joints. It's worth it.
