    When powered on, the Viewsonic VG2021m monitor comes on for a couple seconds and then blanks out. The power LED is still on, but the screen is black.

most probable problem is with the power supply board and inverter, have all electrolytic capacitors checked for leakage and check all solder, specially on the ccfl inverter board.

Gently lay the nonitor, face down, on a table such that it will not be damaged while you remove the base. You will find a curved strip of plastic about 1 1/4 inch wide and 4 inches long. Near the center of this strip, you will find two parallel plastic ridges. These are clips that hold the base to the monitor support post. Squeeze these clips together to remove the base from the support post. I was able to squeeze the rear strip toward the rear of the base and ease the rear of the base off that clip and it came apart ok. It is a bit tricky, but doable. Good luck.

SOURCE: resolution problem of viewsonic VG2021m as the second monitor of thinkpad t61p

Go into the NVidia control panel, create a custom resolution (for the ViewSonic VG2021m, you want 1400x1050, 60Hz), and test it.  When the test asks you if it looks ok and you click "yes", it *still* is not activated-- it is simply added as one of the resolutions available for the monitor, and goes back to the same setting you had before... so it looks like it didn't work.  But then, if you go under "Change resolution", you'll see your new setting is available there.  Choose it, and you are good.

It's working for me, on my T61.

Look at the power supply section for bad caps first, see example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Post back what you see inside, it can also be caused by bad inverter circuits or bad lamps.

Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but the display screen goes blank after a few seconds, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

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..

The Screen comes on for 1 second then goes black but you can still faintly see the image on the screen


It can be as simple as bad DC filter caps (leaking/bulging tops), that will be the first thing to look for, it can be more serious problem in the inverter circuits or bad CCFL assemblies.

Hello, I ordered a Viewsonic VG2021m monitor a while ago, and recently, the monitor shows nothing but black when plugged in. All cables on it have been checked, and my computer acknowledges it is there,...


This is 2006 model year, more likely to have bad caps problem in the power supply, look for caps with leaking/bulging tops first, also look to see if you do have 12~18vdc feeding the inverter circuits.

This your power supply/backlight inverter board:

It comes on for a second when I mess with the connection and then it goes black again.


Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed VIEWSONIC monitors to get some ideas what goes wrong: http://s807.photobucket.com/home/budm/allalbums

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.)
