I have the GEM GL 1821A monitor. After a while, the monitor goes blank and does not respond when I shake the mouse. Initially I unplugged the monitor and plugged it back in and was able to get a response using this process for a while. Now I can not make it come back up no matter what I do. Do you have an idea what the problem is and how I can fix it. By the way, the monitor has a fixed cable to plug into the computer and also a fixed power cord to the transformer box. One more tidbit, the monitor acts similarly on various computers.

Re: GEM GL 1821A black out
At first i would have said it was the video card in your comp,
but if you have tried it on other computers then that cant be the problem.
So if we no its deffinatey not the video card then it is going to be one of two things.
the first thing is its going to be the power pack over heating thid does happen from time to time and can be resolved by replacing the power adaptor this is the cheaper sollution as long as this is the problem,
The other problem it could be is a solder problem because if the monitor comes on everytime and then switches off the chances are if it is not the power pack then it is going to be a bad solder on one of the resistors this is also a common problem with monitors and television.
Now the problem you have got is do you replace the power pack hoping it is that over heating, but if you do this and it is not this that is to fault then you have wasted your money on a power pack that you dont need but hopefully can get a refund on.
Or do you look at the other option a bad solder this is also not very expensive to repair but without knowing what your looking for and without the equipment to check the resistance and finding where the bad solder is.
If you have tried a different power pack then the problem is going to be a bad solder now you can do this yourself but could take ages to find the fault yourself and buying equipment also expensive.
If you can buy a power transformer on the basis you can take it back if this is not the problem i would try this first but make sure you can get refund if it makes no difference.
If you have the equipment to do it yourself and you know aht you are looking for then this should be inexpensive just the price of some solder aslong as you have all equipment if you dont then take to repair shop tell them the problem and they should fix this for a small fee would be alot cheaper than replacing the monitor let me know what you want to do.
If you are capable of doing this yourslef you will need spec sheet but not having an idea what you are looking for will mean you wont find the problem and alot of people totally destroy the unit trying to repair themselves let me know

A high-pitch squeal is common in CRT TV sets and monitors. I've never run across this in an LCD monitor, but there's a first time for everything. If the sound isn't coming through built-in speakers (if this model has them) and is being caused by the computer, I would suspect the inverter circuitry. This provides power for the backlight, and there are transformers that may have become noisy. Because of their construction, it's possible for them to vibrate internally, and at a frequency that you hear as the high-pitched noise. There isn't a lot you can do to quiet them. When I worked on TV sets, I had mixed success using hot-melt glue to muffle the noise, but usually the only way to completely cure the problem was to replace the parts. It's unlikely you'll find the parts available for a monitor, so all I can suggest is to bear with the noise as long as the monitor is otherwise working properly. Or use this as an excuse to buy a new LCD monitor; they are quite reasonably priced these days.
The AC adapter will go into shut down mode if the monitor is drawing too much current due to short circuits in the monitor, but it can also be bad caps in the power supply itself. You can try new adapter or check inside the monitor for shorted components. http://s807.photobucket.com/home/budm/allalbums
Hello sir, I have samsung 22in lcd monitor and nvidea fx5500 card. since last more than 6 months, my monitor goes blank If system remains idle (means I don't move mouse and don't touch keyboard) for 1 minute. After monitor goes blank I have to move mouse to brink it back to on. The power led keep on during this problem. I tried everything including power options in windows but could not fix it. Is it bios setting to be checked or could it be windows bug? Please help
