Help! NEC LT380 picture problems

A tenant moved out and left this NEC LT380 projector behind.. I've always wanted a projector so I was hoping this one would work, unfortunately the picture is not right. It seems like it can't make whites look white, they are yellow tinted, and other colors are off.

I've gone through all the color settings, screen colors, ect with no change. I was projecting onto a white dry erase board, also tried a white painted wall, no difference. I bought a cheap ($58) new bulb off eBay hoping it was a bulb problem but it didn't change anything at all.

Can anyone suggest what I should try to do to get this projector working correctly? I've tried my computer using VGA output, and also my GoPro camera directly to the component in, same results.

Here is a sample of how it looks, with my laptop display in the foreground.

I was going to include a picture but this is my first post and I cannot.....maybe soon

thanks

At first, I thought maybe a polarizer is toasted, which is not uncommon in an LCD projector with a number of hours on it. This just looks like you're not getting any blue. It might be as simple as your VGA cable. Try using an HDMI source via the DVI input on the projector. If that doesn't work, you'll know why the projector was left behind.

Thanks for the reply. Do you think using the DVI input will make a difference vs the VGA or Component in? I also did try the component in with a different source.

Is repairing the polarizer possible or worth it? Something I could do myself? It did have ton of hours on it when I checked, I think 3 or 4 or maybe even 6 thousand hours I forget.

That's a lot of hours on a business-class projector. Probably not worth it. You'd probably be better off buying a referb HT projector at Tiger Direct.
