The issue that your having is very common and is an indicator that the monitor's Power Supply is failing. We repair them on a daily basis for about $60 but its rare to find a company who will touch them.
We've had the best luck and feedback on the HP LCD Monitors from Staples or Office Depot and seem to always be on sale.
Hope this helps,
I dont believe they have anything local and if they did it would cost around $200 for them to fix it. The cost of a power supply is about $150 retail, but the parts that go bad are a lot cheaper to just diagnose and replace.
And lastly I would rate my diagnosis a 9 as I fix these monitors in my shop almost daily.
The parts that go bad are the filter output capacitors. The reason these go bad is because they are filled with an electrolytic acid that dries out over time, then turns into gas causing the cap. to swell and loose its capacitance or charge like a battery.
Yes it did and I appreciate the Positive Feedback you left as well.
Best of luck on your repairs, and Im always here to help you further.
