Laptop screen has color vertical lines - moving

Dell Latitude CPi Laptop. Windows 98, Pentium II. When I booted up my laptop this morning after about 3-5 minutes the screen started having verical color lines on the screen. They covered just about the whole screen and every few minutes you could see the desktop in the background. Is the cause of this a major expense or just a minor repair? Never had it happen before?

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
