Re: My ViewSonic monitor just blacks out for no reason
It could be a setting you could have done on the "Power Saving" settings under "Screen Saver" settings, if you have Windows XP. Like "Turn off monitor after" a certain time. Even if you don't have Windows, please check the Power Save settings.

Hi, well if this is the inverter board, then its probably more cost effective to buy a new screen, same thing if this is the cathode lights. Reason for that is the technician will charge to replace, so cost will get anywhere from 50 and up. Only one question, how many years old is it? I do believe Viewsonic has 3 year warranties.
Monitor going black after a few seconds can be caused by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4
bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.
Check to see if the image is Dimmed. Chances are the power supply on the FPD is either dead or not supplying power to the back lights.
Your problem is the power supply or the inverter on your board, you can replace it and it will be fixed. Easy Fix REALLY EASY FIX (inverter is what supplies power to your backlights. A lot of the times the reason a monitor goes black and the green power button is on, is because the backlights shut off. in most designs of the 1730 the inverter is embedded on the power supply. That is most often the case on this problem. Power supply/Inverter=Replace it and you will have a spanking new looking nice monitor working again. :)
Problem solved! The main power thingy (the thing with the big red wire coming out of it) was all black and dusty. There was 'soot' all over the whole insides of the monitor. I concluded that this monitor should be laid to rest, and a new flat-screen monitor erected in its place.
My ViewSnic 175b monitor goes black after about 1/2 hour working. In addition the words/letters typed after the blackness do not appear in the text input box.
This started happening after my last ZoneAlarmSuite Update and virus scan last Friday. Prior to that no problems at all. Any help gratefully recieved.. ...
