When I turned it it has a black screen, the entire screen is black and none of the keys do anything. I replaced the batteries.


I think your keys still work, but you need to adjust your contrast. To adjust the contrast by lightening the screen, press and release the "2nd" button and hold the down arrow. Reply back if this doesn't work. Hope this solution helps!

I cant get the color right. its to red??? any help? i did notice with the back cover off, there are 6 adjustment screws


yes! those are the screen and focus adjustments. 3 for screen, 3 for focus. try this. go in menu....turn down color, brightness, contrast all they way down. you should then have no picture, but in your case a little red. then go to back of tv and turn those 3 screen adjustments all the way down. slowly turn the screens back up until you get barely a picture. because remember, your brightness and contrast is all the way down. the picture should be dim but seeable and with red, green, blue adjustments, make it a black and white picture. when balanced..... turn up color , brightness, contrast in menu. enjoy!

Black screen


Try adjusting the contrast. It may be too dark. Turn the calculator on press the 2nd key and the down arrow. This is how to adjust the contrast and will lighten the screen. You can darken the screen the same way, but use the up arrow instead.

Monitor dims on a black background hanns G 28


Go into monitor settings and turn "off" X-Contrast. X-Contrast will auto change contrast when backgrounds darkens. However, adjust manually the Brightness and Contrast settings to compensate.

Difficulty reading screen


As an FYI....The arrow keys control many things,
If not in use, they control the contrast.
If ringing, it adjusts ringing.
when using handset or speaker, it adjusts volume.

Dark screen


Turns out the little button on the top left of the device is for adjusting the contrast. Turn on the WorkPad. Press the little button. Then hold down the down button and the contrast will be adjusted.
