Hi, Stevie and welcome to the forum!
Was it blowing the circuit breakers in you home. The bulb may have blow because it had reached it's hours of use(about 50 hours) or the lamp sockets could be corroded. Buy a can of contact cleaner and spray the lamp sockets. Also, buy a tube of Lithium Grease from you hardware store(abut 3£) and apply to the gears in the back of the projector. Sparingly! The bulbs are readily available on Ebay UK. Below is a link that has 5 for 19£ and free shipping. The Chinon, like Bill says, uses an EFP 12v 100watt lamp.
If you could post some pix of the lamp housing area and the inside of the back, that would help.
