Thank you for the input. My screen flickers when I move the lid/ 
screen back and forth (e.g., open to close postions). The screen  
ususally does not work, but sometimes it does. I think it may be a  
fault inverter. Have you replaced and inverter? Is it easier than  
trying to replace a lamp tube?

I don't think it is the video, because I can plug in an external  
monitor and all works fine.
