Repair/service guide for a Panasonic PT-L500U projector?

My Panasonic PT-L500U projector won't turn on unless you hold he cord in a specific position. I have replaced the power cord and the problem persists, I'm assuming there is something wrong with the "AC in" socket. It could be a wobbly pin or maybe something just inside, but it's definitely affected by the position of the power cord.
