I have a copy of the service manual which contains service information - electrical adjustments - troubleshooting - spare parts - block diagram - frame schematic diagram. If you want the copy, let me know your email add and I will send it to you for free.

You can make all sorts of adjustments. From your description, it sounds like the contrast and brightness are mis-adjusted.

If you do not have the manual, you can download it from here.

Best of luck, Jim

if you are using a laptop,hold down function and press the display key until it clones both screens,if you are using a computer,make sure the connections are secure,also try and make sure that the source is from the computer/laptop and not s-video or component video.

also try replacing the vga/dvi cord.

open up the top case. the fuse will be on the power supply board right next to where the power cord plugs in. you'll need a continuity tester to test it. if it is blown, replace it with the exact size and type. if it is not blown, replace the power supply.
