I have a GEM 17" TFT LCD Monitor (GL-821A). It does not seen to have any power to it. The wall outlet is good. The indicator light on the transformer lights momentarily and then goes out. I push the power button and it barely flickers once then will not relight.

Sounds like your power supply capacitors are causing the power supply to shut down. Or you have a short in the monitor loading the power supply. You should try a different power supply.

Installed windows 7 on a dell sx260 with gem 17 lcd cant get display drivers to work?screen all dis colored


Try going to the Dell or Microsoft Websites and loading a new display driver for Windows 7. When I first got Windows 7, both my monitor and printers required new drivers for Windows 7. It seems that Vista and XP drivers for a lot of things don't work on Win 7.

Good Luck

Power Issues!


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.

I didn't use the monitor for some time now when I connect it it flickers on and off is there a way to reset it? GL-821a 17" flat lcd monitors


Probably no reset function but a power supply with some failing electrolytic capacitors which can age even when not in use if they were poorly manufactured.

GEM GL-821A has no display. The activity line does change from yellow to green. There is power to the display. What is wrong with it?


- lower resolution on computer ti 800 x 600 - look on screen to see faint image, if so, then inverter or backlight is gone.
