To adjust the display settings:

1. Press the flywheel control. The main menu appears.

The current display settings appear across the top of the main menu.

2. Rotate the flywheel to highlight an option. The name of the
highlighted option appears in the center of the menu.

3. Press the flywheel control to select the highlighted option, then
rotate the flywheel to adjust it.

Some options can only be enabled or disabled. There are also some
options that contain additional menus.

4. Repeat Steps 2 and 3 until you have made all your changes.

5. Rotate the flywheel control until Exit is highlighted, then press
it to exit the OSD control system.

Manager menu.

Try going into the control panel and select power options see if there is way to adjust the display brightness or try holding down the "Fn" key and use F7 to increase the brightness

dont know what kind of monitor you have but there should be some buttons on it to adjust things like contrast, brightness, screen size etc.. try that first

if not go to--

start -> control panel -> display -> settings -> advanced -> there should be a tab for your graphics driver software in there. try changing the screen size

Its aproblem of command section.Check its components one by one.you can identify this section (the front panal buttons goes in this section and a ic in big size and pasted horizantally in the circuit).if the components are ok then change command ic with new one.This will solve your problem.

try this option press hold menu en arrow button to adjust setting en fix it for your best display set your resolution on 1024x768 60hz after that disable osd by removing resistor located on crt board loc# r117 tnx and good day.

Brightness is adjusted by using the 2 buttons on the left side of the front.
