Chances are it is the Power Supply. It is a Megmeet MLT386X which is hard to find, but sometimes IS available on ebay. There are places that will repair the old one advertising on ebay as well. If you remove the covers running across the heat sinks and see that the capacitors are bulging, the repairs are within the capability of anyone who knows how to use a soldering iron. If you are handy with a soldering iron, LCDalternatives sells a kit with ALL electrolytic capacitors prone to fail for $15.95 plus shipping. I bought the kit and fixed mine. It took a couple of hours to unsolder and replace the capacitors. Powered up and has run for last two years with no problems.
