    Blue light flashes, but screen stays blank. No repsonse to reboot, or presseing any keys. Self test with signal cable does not work.

You have to check if you can see the image on the screen or not after it went blank (Power on both CPU and monitor) by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like mine, I can see window image using flashlight and check lamps inside. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.
Thank you

Screen blinks on /off - can syncmaster 931b be repaired?

This model was released in 2001, you need to open it up and look for bad caps with bulging top first, the problem can also be in the backlight inverter circuits. Post back what you see so we can guide you further, see example of failed SAMSUNG monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
