Can you brighten the display on the phone - GE Cordless Phone 900 MHz

go to settings and find picture controls then find brightness

There is no way to brighten the display. If it's dimmer than it was when new, the control board will need to be replaced.

If you need further help, I’m available over the phone at https://www.6ya.com/expert/jeffrey_634abadf963e31e5

screen and wallpaper setting turn of auto light and screen will be bright again and not dim.

Since you didn't give the model of your VTech phone, I can only suggest you enter it into the search box at http://www.vtechphones.com/support/general/manuals to download a copy of the manual.

try restarting it, If that does not help, take it to your local dealer.

steps:
1. settings
2.Display settings
3. Backlight
4.Display
5.Brightness

Then brighten it. You brighten it by Holding Down either FN, CTRL or DEL key + Hit the corresponding key for brightening the display.
For example on my computer I press and hold the FN Function key while I hit the UP Arrow key to brighten the screen.

The brighten/darken keys normally have the icon of a circle with sprockets around it like the sun or it looks like a washer that goes between a screw.

It may be the backlighting has been readjusted by someone other yourself. Whenever you go on battery, I'm sure you've seen the screen darken a bit. This is the backlighting being turned down to save battery life. There is usually a blue function "fn" key that allows the user to brighten or darken the display. Look at the blue icons in the F1-F12 keys. The one to brighten the display looks light a sun and the one to darken the display looks a full moon eclipsed. Press and hold the fn key and tap the desired function key to brighten or darken the display.

There is no way of brightening the LCD however the Prostar 816 display phone, however it is designed so that the display tilts to deflect the lights. I'm sorry this isn't really a help. however I have uploaded 1 of almost 70 videos which may help you with any further issues on the Prostar 816. more tips on training on
