My M992 powers up but there is no display. It has been in a closet for about a month and was working fine before it's temporary retirement. Not even the Seft Test Feature Check. Any ideas on what the problem may be? Is this worth having someone else repair?

It's clear the problem is the display, but you can still try these 1. unplug and replug while the both is on 2. turn on, off couple of times 3. keep the LCD on for about one hour
these are anyway temporary fixes :(
If it's getting no signal, make sure the monitor is set for the correct input. This would be either analog (if your cord has blue ends) or digital (if the connectors are white). Depending on wt yhat your monitor is, a button on the monitor will help you set that. If it's set for the correct input signal, then switch out a different cable to see if perchance you have a bad cable out of the box. If there is another PC or laptop setting around, plug your monitor into that to make sure it's good and maybe even plug THAT monitor into yours to make sure there is nothing wrong with your video card. Let me know what transpires. If this takes care of things, please help me out by rating it accordingly.
Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages. Good Luck!
The link below is a Digitally signed M992 monitor driver.
Also try upgrading to the latest ATI software and drivers. You can also try and change the frequency refresh rate to 75mhz. It in the Control Panel under 'Display' and tab 'Monitor'.
It shows a list for frequencies you can try.
