Viewsonic n3250w LCD goes into unwanted standby mode

    I work at a school that has 2 Viewsonic n3250w LCD monitors in the
    main lobby for announcements, etc. One of them, after being on for a
    little more than 1hr will go into a "standby" mode. The audio will go
    off and the screen will go almost completely dim, you can still see
    the picture, but barely. I have gone through the menus and find no
    setting for this or any way to turn it off. The strange thing is that
    the other LCD display has never had this issue.

    Does anyone else have this problem? Any suggestions on how to resolve
    it?

    Thanks.

    Erm... You have turned off the monitor settings for power savings, right?
    You didn't specify your OS.
     
  3. I guess I need to clarify, then. The 2 displays are mounted in the
    school's lobby. VGA cables run back to an office where they connect to
    a computer (WinXP SP2). It was just suggested to me to turn off all
    power saving settings, i will see if that works. The speakers for the
    audio are on the monitor itself. When the one display goes into this
    "standby" state, the audio goes off.

    I would expect to see that behavior when power management kicks in. The
    onboard amp in monitors I've worked on also have power management, which
    is controlled by the LCD controller. You might try swapping the VGA cables
    at the monitor ends and see if the problem follows one of the VGA ports.

    I also have this problem with my n3250w - ANY input (PC, tuner, A/V,
    etc.) will just quit after 1-2 hours.

    The audio pops, the screen goes blank, and the remote will not work.
    Only turning the unit off at the set button, then turning it back on
    works (only for an hour or so more, then repeat).

    It seems like it's overheating or something. Anyone have any ideas?

    I can confirm that this problem is NOT power management.
