How do I delete technical information that remains on my screen?

Depends on what you mean by "not start"
1. You press the on button and NOTHING HAPPENS
2. Press on and only computer light indicates on but sceen remains black
3. starts setup but screen remains black or you just see a blinking underscore
4. Starts up and you get some message
5. You see OS screen but then goes black and you get noting more
6. Something else?
May you be more specific about "not trart" by reformulating your question
Anyway, if you don't have some technical experience insstalling, reistalling or running repair applicatons, maybe you should find a good repait shop to avoid more trouble

Press MENU on the remote (with the projector running of course).
In the window that comes up on screen, there are a series of icons on the left side of the screen, and the currently selected one will be highlighted (yellow if memory serves me correctly) scroll down through the icons to the very last one - the Information icon.
Press ENTER
The Lamp Timer (lamp hours) will now be showing on the screen, below technical info about the current signal feeding the projector. The 'Lamp Timer' information is at about the centre of the screen :o)
