Monitor Buzzes then Resets

Today, my 24" Envision G416 LCD Monitor buzzed for a little while, then reset. As soon as it turned itself back on, it turned itself back off again, so I shut the monitor off.

The buzzing/oscillating sound from the back of the screen has been happening only for a very short time right when I turn the monitor on. This went on for a few weeks till its demise today.

There was one more symptom. For the past few weeks, when the monitor is in stand-by mode, there's this really high pitched, but somewhat subtle, repeating noise that sounds like an alarm going off, or like a signal repeating.

Any idea what component might have gone out in the monitor and how expensive it is to fix?

Thanks so much!

    sounds like a bad power supply, not worth repairing unfortunately considering how cheap a new unit is.

    So it would cost less to purchase a new monitor for around $300 than to have someone fix the power supply in the monitor? That's too bad. 24" monitors are pricey.
  3. you can get a decent 24" for around $150. i charge $90 an hour plus parts, so unfortunately most electronics are throw away items at this point.
  4. Sounds like bad electrolytic capacitors. They can be replaced it it is a pain in the butt to get to them power board
    in most monitors.
