That sounds like possibly a bad cable or a bad video card. Do you have another cable you can try?

SOURCE: No display, green light on ViewSonic VP201b 20.1 LCD

I have two broken VP201 monitors with different symptoms. One was black screen green light - like yours. The other was purple speks flying all over the screen., purple tint.

I swapped the power supplies and display boards, both monitors had original problems. I swap the inverters and the monitor which was black screen now appeared to work okay - but slightly pink and the monitor which was purple speks is now black screen.

I would therefore assume that both my inverters gone, one being on it's way out. You probably have the black-screen case.

hramirez, Retevo. com says time to retire this old monitor. Its that or you will need to do some extensive reading here on fixya on how and what to look for inside the unit that could be causing your black screen condition!!! Then you will go to YOUTUBE and view some of the many video clips that deal with "lcd monitor repair" and lcd monitor disassembly". Have you noticed any bad, swollen top, elcetrolytic filter capacitors on the units "switch-mode-power-supply/CCFL inverter printed circuit board?? How about any "cold" frosty looking solder joints around the component leads of the power transistors and ferrite inverter transformers? May need to get large magnifying glass to find those pesky little cold solder joints. 12fixlouie

SOURCE: how to degauss viewsonic vp201b

You do not degauss LCD monitor, it does not use electron beams (affected by magnetic field, if the showdow mask is magnetized, it can mees up color display) for making pictures like LCD.
You only degauss CRT type monitor.

ViewSonic VP201b with Black screen. I think the problem is the back light power supply. If I shine a light on it at an angle I can see the image on the screen. what is the part number to get a replac


Hello,

The power supply board is model L20C-2 In most cases you can repair the board cheaper than you can purchase a new one. The problem is the filter capacitors go out and this keeps the back light bulbs from powering up right. If you feel like doing the repair on the board here is a link that shows the board with the bad parts circled and a parts list on the capacitors that needs to be replaced.

Vp201b wont turn on


Checkto see if you do have 12vdc output from the power supply module as shown in my pictures: http://s807.photobucket.com/albums/yy352/budm/Viewsonic%20VP201B/

Look for bad caps (leaking/bulging tops).

Display flickers than scrambles.


Most likely loose connection at PC. Check that monitor connector pins are not bent. Ensure that he monitor plug screws are screwed into the connector to prevent plug movement, at the PC and in the case of some monitors, also at the back of the monitor. If this does not correct the problem, there is probably a fracture in one of the solder joints on the VGA board at the connector.

Screen jumps back to prior screen


If you mean to say that the computer-generated displayed image on your screen changes, it's a function of the computer, not the monitor. If you mean to say that some monitor-generated displayed image is appearing (such as a setup/configuration menu or a splash screen), please tell us more so we can diagnose further.

Monitor distorting in screen halves after warmup


It probably isn't worth repairing as the cost will exceed what you would spend on replacing it.

LP70+ projects a dark rose/pink tint upon the screen


The pink tint produced by my LP70+ projector was not a lamp issue but a connectivity issue. I swapped the old cable with a good known cable and the tint went away.
