Hi...there,
It's seems your LCD Monitor backlight inverter it burnt out. Need a new inverter. Have a nice day!

SOURCE: Viewsonic monitor VG2021m won't awaken

I understand the vg2021m has a 3 year warranty. Phone number for Product Support is (800) 688-6688. Give 'em a call and see if they won't fix it for free or some nominal charge. (OK! So this is the cowards way out.)

there is atleast a 5 year difference between your computers. Technology has made a huge jump from back then, especially in graphics cards!!! that LCD was probably made after your computer, alot after your computer as a matter of fact. So it is your graphics card. get a new computer, its time to update

Hi!
there are possible reasons why your monitor shows nothing on your screen...

First, you need to check if the power cable of your monitor is well connected to a wall socket or AVR (and that you are sure there is supply output current on the AVR or in the wall outlet)

IF found that power cable is fix and secure... my suggestion is you bring the monitor to a credible technician...Because the possible reason why only black is seen on your screen, is because the backlight inverter could be busted already.. the backlight inverter which is located on the upper and lower back edge of the monitor is the light source responsible for giving image display of your lcd monitor.. Another reason could be is a deffective high voltage ballast transformer which is responsible for generating high votlage supply for the backlight....

It is too risky for you to do the repair by yourself without proper knowledge and right tools to do this.. So don't waste time consult a technician and or possible avail of the warranty if there is any...

Hope it is clear now to you..


Much appreciated if you rate this help.. thanks..
