Hi, I have a asus VW192DR lcd monitor but it cannot open properly, only mixed colors, is there any chance that i can fix it on my own? pls help.


ASUS DISPLAYS are pretty FUZZY, HARD TO REPAIR but also HD and VIVID. ASUS DISPLAYS are usually HARD SEALED from the inside. Try paying it a rest and RESTARTING . Doesn't work? , DETACH the STAND to make it easy to work. The SCREWS to OPEN an LCD MONITOR are usually near the VGA/DVI/HDMI CONNECTORS. HOPE THIS HELPS.

My samsung 22" lcd tv


The only thing that comes to mind, as you haven't said if you have had it working on it or not, is the fact that it is not capable of handling the resolution you have got set on your computer. to fix this set your computer to a low resolution, connect to your TV and see if it works. If it does increase your resolution setting until it stops working. (if you get it wrong it will revert to the setting before). Hope this helps.

Benq fp222w monitor switches on but black screen no backlight what parts need replacing to fix pls


If there's no backlighting but you can see the image anyway, then your monitor might have a defective inverter. The inverter is responsible for providing power to the backlight, so if it is defective, the light won't work and it might need to be replaced.
An LCD inverter looks something like this:

You can easily find inverters for sale online, but be careful: you have to find the exact same inverter for your monitor, or it may not work.
