Question about ViewSonic VG2021m LCD Monitor

Open Question

Viewsonic VG2021m doesn't work

Problem, posted last week. 12fixlouie asked for clarifications.
my answers are:
1) I see 1 fuse on the circuit board where the AC cord plugs in.
2) I don't see any cracks or stresses in the inverters circuit. I guess this is where the two transistors (40T040 650045) are mounted.
3) No discolouration visible on the board.
4) Electrolytic caps are 'TAICON' and 'CapXon'.
5) No I don't know the flashlight test.
6) No, I haven't tried swapping with my monitor that works, (Samung SynchMaster 171v)

SOURCE: Viewsonic monitor not detected after service

Hello,
If you are running DVI-D(the white connector) then it isn't getting a digital handshake. If you have inspected the connection between the 2 and make sure there is no bent pins inside the connector that it mates with. If you have another computer, try to connect to that one.
Open windows start menu, right click on my computer, then choose properties. Next choose Hardware, then Device manager. Once there, double click on display adapters to see if installed correctly. If good, click Monitors. If good, then your video card driver must need reinstall or update as usual. Also do you have the correct driver for you monitor? How does it react when you uninstall the monitor driver(can you select 32bit and higher resolution in default drivers?
If none of this works, I would suspect that the replaced component failed due to static or faulty components within the electronics.
Is there any other changes to the PC (new video card, updated Directx9.0?)

Hope this helps and let me know if I can be of anymore assistance?

SOURCE: viewsonic vg2021m base mount

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.

Here is a suggestion:
By looking at the power board you should see the light, and where it is connected to, so diagnose the circut from that point foreward eliminating any potential of damging the board. try any cables or ribbons.

My VG2021m´s sound doesn´t want to work. The mute button is off. The volume is up. And there´s still no sound.


Did you varify that the sound card in the PC is working? You can try feeding the the monitor with sound source from MP3 player to see if you do get the sound OK or not, to have the sound circuits repair by the shop will not be worth it because the money will be better spent on good set of powered spekers system with better sound than the monitor built-in speakers.

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:

Viewsonic VG2021m Image Vanishes on Start Up


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.

My ViewSonic VG2021M LCD computer screen has died on me. For the past two weeks it took 2 or 3 minutes to "warm up" before it would start working, and not it has completely stopped. Some have said that it...


I can easily see 4 bad caps (black case) with bulging tops, the other two caps (green case) should also be replaced at the same time, use only good caps, PANASONIC FM or FC series from DIGIKEY, higher value and voltage are OK to use. Learn more about what bad caps look like:

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
Post back what you see inside so we can guide you further.

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.)
