Question about ViewSonic VG2021m LCD Monitor
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)

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.

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.
