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 pink tint on screen


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

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.

Hi, I have a ViewSonic VP201b monitor that has a problem.... It seems that it wont turn on (BLACK SCREEN *NOTHING*). The yellow light goes on when idle, but when it's not idle the green light isn't...


Get a working monitor and turn on the computer. Then swap the monitor with VP201b.

Get a flash light closer to the screen to see whether you can see the desktop screen image. Yes? Then it is your backlight inverter.

Find a Youtube video to show you how to open the cover. Then look for any sign of broken capacitor(s). Replace them and then test your monitor. If all capacitors are okay, it is one of your FUSES. There are 2 tiny surface mount fuses ("FN" type). You can short the two ends to test it before removing them. Often only one of them is broken. Replace it and the monitor shall be okay now.

ViewSonic VP201b with a black screen


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

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.

My viewsonic VA800 just started getting all pixillated - does it need to be degaussed?


mitchpowell, CRT monitors need to be "degaussed". No need for that with CCFL back-lit LCD displays. 12fixlouie

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.
