    Unusual Monitor Issue

    I have an 8 year old Samsung SyncMaster 244T that I'm in the process of replacing due to age and some other issues.
    It's been a good monitor for the time I've had it, a hell of a workhorse, but it's getting a little long in the tooth.

    Lately (the last 6 months to a year) when I've powered down/off the monitor or computer, occasionally, it will not power back up.
    [meaning: no monitor picture or missing cable signal. The front power LED displays a very dim and blinking light]
    I get the very faint green flickering light on the front power button, but not the green full on LED or full green blinking LED.
    This, ever increasingly, requires some coaxing: Turn off power, unplug power and DVI cable, then, replace power cord to outlet, watch
    for solid blinking green LED to come on, then wait for the "check signal cable" to appear on screen before I can plug the DVI cable back in and
    effectively get started using the monitor.

    50% of the time it doesn't and I have to repeat the steps, sometimes a half dozen or so times allowing for breaks in between.
    Only when I can get the front power button LED lit up fully will it post the "check signal cable".

    Otherwise the monitor functions well when it is on.

    I'm thinking it maybe a PSU issue within the monitor itself.

    Does anybody have any ideas about this, or has had experiences similar?


    Thanks

    Hi CLiNT,

    1. First i would do the "Monitor self test" for clues.

    2. Next... "open-er-up" and check for bulging capacitors ... sounds like something is "Loading" the power supply ...If a "Cap" goes "Resistive" that would do it... Regards Fred

    Thanks Fred, I'll open it up & have a look once my replacement gets here in a few days.
    The monitor's self test is unremarkable, as long as the front power button's solid green LED comes on- otherwise there's nothing.

    CliNT,

    After 8 years sounds like it's time to B&S (Butch & Sundance) that monitor.

    A few days back when it took me 2 hrs trying to revive it I wanted to.
    Yeah, eight years is a long time. I've never had any problems with it, so it just passed from one build to the next.

    Update:
    Upon opening the monitor and visually inspecting the circuit board, there appears to be
    three capacitors that are somewhat bulging on their tops. (in comparison to others) They appear
    to be associated with the monitor's power supply unit circuit board .

    I don't think I'll go through the trouble of replacing them though.

    Thanks Fred

    Hi CLiNT,

    You should do it, if only for the experience of changing them... Removing "Caps" on a circuit board is a very tricky affair , and requires special tools... ...So if you don't care about "klunging" the board ...You should give it a go. Never stop learning ... Regards Fred
