I recently purchased this projector used for well under the MSRP. It had been working fine for a couple weeks up until yesterday when a red "ghost" image started to appear after a couple minutes of use. At first, turning it off then on would make it disappear, but eventually it was stuck this way. Now the lamp won't even come on. I'm a college student on a budget who uses it primarily for DVDs and games. Do I need to replace the lamp? Or does the projector need to be serviced (by myself or a professional)? Is it even fixable or did I get what I payed for?
