This is just a guess, but it's an LCD projector, it's possible the LCD itself is going bad. It's common for LCD panels to develop vertical lines when they are failing.

Just an idea,

I have the same projector and had the same problem, the main board was replaced under warranty and the lines went away.  6 months later they are back again.  The projector can handle a high resolution so that is not the problem.  The white lines appear even when no source is connected (splash screen)

Sometimes if the resolution is set too high, white lines will appear.

How do I Fix LCD White Screen?

If you see "fractured lines" across the screen, it would appear that your LCD screen is broken. That's the only way these kinds of lines appear.
You need to replace the screen.

Trouble with output to the projector

Hi there

Check the following on your laptop.

Right click on your desktop , go to properties and settings - check if your resolution of the PC is the same as that of your Projector. i.e. 800x600 or 1024x768

Also check that your secondary monitor is attached / activated.

If the signal stil won't pick up - hold down the Fn ( function button) left of your spacebar and press in your F-row of buttons the one with 2 screens on it. ( differs from brand and model )

Hope this helps you and good luck with your class tomorrow !
