Having problems with your 3G Technology GL1821a (Black) 18 in. Flat Panel LCD Monitor ?

GEM GL 1821A black out

\015 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.\015

Answers :

At first i would have said it was the video card in your comp,
\015\012but if you have tried it on other computers then that cant be the problem.
\015\012So if we no its deffinatey not the video card then it is going to be one of two things.
\015\012the 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,
\015\012The 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.
\015\012Now 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.
\015\012Or 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.
\015\012If 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.
\015\012If 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.
\015\012If 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.
\015\012If 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
