Projector Repair(or Not)

So I was on a walk with some friends an i stumble upon a projector in the trash. When I plugged it in it ran but the fan in the back was broken. I then opened up the case a hot wired in a new 40mm fan. When i put it back together, though, there were discolored bars on the sides so I opened it up again to see if i could fix it. I fiddled with it for a wile ad blew the dust out but to no avail. I was not able to fix my protector.
