I don't know this particular model, but there are a few things you can check should you wish to retain the monitor.

1) If the unit has the older rotating controls, try spraying them with electronics switch cleaner (with lubricant). Work them back and forth a few times with the power off.

2) If the controls are the tact switch type, with the power off, press all of them and you should feel them engage. If not, replace the switches. They should be available generically for about 25-50 cents each.

Sounds like your monitor is going bad. You might get some more use out of it if you power it off for a couple hours and try again but my guess is this is a heat-related failure that is common on ViewSonic monitors.

A 15-inch CRT monitor? It's time to responsibly recycle it, and buy a 17-inch LCD monitor, because _nobody_ fixes CRT monitors any more.

Hi,
This problem is due to a defective microswitch in the brightness and contrast button of your monitor. To rectify this problem, you'll have to replace this microswitch. Please refer the servicing to a trained repair technician.

Hope this solves your problem. Thanks.

Brightness and contrast control screen always appears on screen


It is a disguisting problem which I am myself facing. This causes due to moisture on the monitor curcuit components and the curcuit pads get pressed. This can only be solved when by replacing rusted parts. Contact a monitor enjineer.
