Word BOOT on screen of zehnder sat box then blank...help

let it charge overnight then when pressing the "on" button, hold it till something starts happening. I have to hold mine till I see the screen start to activate.

The bad thing about this is that it could be a software related issue or a hardware issue. If you're willing, you can disassemble the unit and check for a damaged or loose connector to the monitor. If there doesn't appear to be any issues there it may well be that the screen has gone bad or there is something wrong with the driver/setting on the unit itself that is causing the screen to saty off. I'd move forward with the hardware issue first though.

Hi,
1) You should try restarting it, maby that will solve the problem.
2) If that does not happen, then go to a computer specialist, there maby is something wrong with your Display.

If you can tell me what the Os do you use, it could be must better.

On XP you can try this:
Boot computer and press Ctrl+Alt+Delete twice when you See Windows welcome screen / login screen. It'll show classic login box. Now type "Administrator" (without quotes) in username field and leave password field blank, press Enter and you should be able to login Windows.
Now you can reset your account password from "Control Panel -> User Accounts".

On Win 7 or Vista:
Ctrl+Alt+Delete won't work, you have to use some windows password reset tool. I recommend Windows Password Reset.
