dustcore025, Need a little more info here. Do you know age of monitor? Was it or did it display a "perfect' image on it the day before? Is it under warranty? How far are you willing to go to try and repair this thing? Do you know how to "part" the snap together plastic back cover from the bezel, after removing the pedestal? This sounds to me like a Switch-mode-power-supply or Inverter problem that occurs when some Electrolytic Filter Capacitors get a little bit TIRED of being constantly subjected to high temperatures near heatsinks that are used to keep semiconductors within operating limits. You can determine how bad this may be if you can do a test and remember what happens. Here is what to do. Make sure PC is fully booted displaying WIN desktop or some other screen. Next, with someone to keep hitting the CTRL or SP bar key every 20-40 seconds while you reconnect both cables of your MM17 back to the PC video port and ac outlet. Now try to turn on the monitor and note exactly what you see and for how long. Did it have a sharp clear image, even for 1-2 seconds? did the screen go black? OK! Next thing is to shine a bright flashlight onto the screen 2 inches away from where you know there was something a few seconds ago. Try it at different angles and not if you see anything. get back to me with results of test. I'm louie12fix on fixya or lmistyrel @ aol.com BYE for now.

These have bad inverter boards, the part number is: 1FSA10164 for the MUT cba which includes the inverter board. The boards have about ten plugs and 8 screws after you get the back off.

These TV's are somewhat sensitive to internal heat. It appears your sensor has triggered an overheat. This doesnt mean you still have the heat issue, it just saying it needs to be replaced or reset, either way it is not something you can do in your home. Taking it to your local authorized shop will ensure proper repairs, about $90 worth.
