When I turn on the monitor, it will turn off. I have to repeat this process a number of times until it will stay on. And over the course of time the number of times I have to do this has increased. Today it took about an hour for it to finally stay on. This is beyond frustrating.

Plug the AC adapter into the
back of the scanner and into a wall electrical outlet. Screw the antenna
into the receptacle on the back of the scanner (extend the antenna to
full length for best reception).
Set the squelch level to allow
signals to be heard by turning the squelch knob counterclockwise. Rotate
the volume knob clockwise until you hear static. Slowly turn the
squelch knob clockwise until the static noise disappears.
Start programming frequencies into the scanner by pressing the "Manual" button.
Press the up arrow or down arrow key until the channel you wish to program is visible on the display.
Use the numbers on the keypad to enter the frequency for the local transmitter you wish to receive.
Press the "E" key to complete the process of entering the frequency.
Repeat steps 3 through 6 for each additional frequency you wish to monitor.
Press the "Scan" key to start
the scanning process. The scanner stops on a channel when it detects a
signal strong enough to hear over the squelch setting. Two seconds after
the signal stops, the scanning process resumes.

It sounds like the back light on the screen is faulty. If this is the case it is definitely a return for repair problem. You should be able to find the warrantly procedure for your area on the samsung website.
At this point I assume you've tried to go into SAFE mode, and into BIOS with no luck. You're right about the overheating but I think the damage is done. If the unit will no longer stay on in any mode or condition then heat has ruined something. First easiest part to check is memory. The check the CPU (most laptops still have a plug in CPU). If neither of these are suspect then take everything off the motherboard, including the screen (I use and external monitor). If the problem still exists then it's time to use a scope.

it is not a bad rom. if it was a rom it would constantly act up but it only acts up upon overheating. The solution is difficult but if you open the monitor you can find all of the heatsinks take them of and replace them with bigger ones. or have a fan blowing on it at all time it is active i added bigger heatsinks to my emachine le1799 and it solved this problem of pulling up menu and changing setting by itself and the lack of the ability to turn power of.
