Thought I would go straight to the experts on this issue...
As many of you know I have been screening a number of films and posting shots on the forum. Believe it or not, I did get through my last feature and the lamp went out on my projector. I thought no problem... simple bulb change... not so much.
I have tried several bulbs... but alas no light...
Any suggestions? Could it be a fuse? something else?
Any and all advice greatly appreciated.
Cheers,
Richard

I would be 99% sure your problem will be with the internal contacts "where the lamp pins make contact" that burn out over time on the lamp holder.

I agree with Graham. First thing to check is that lamp socket. GS1200'S are notorious for lamp socket failure as the flat contacts only actually have a line contact with the round pins of the bulb. Change the socket to one that has cylindrical shaped sockets that grab the pins of the bulb all around the exterior surface area.
I have had several of the Elmo sockets burn out, and have had no problems when they were replaced with the round sockets. Even these, though, need periodic replacement every few years because the intense heat of the bulb weekens the spring force of the contacts.

Gentlemen,
Thanks very much for the quick reply. What you say makes perfect sense.
A few more questions. How hard is it to change the lamp socket? Is it something that I could do, assuming I can get a new socket somewhere?
Again, thanks to you both.
Cheers,
Richard

Hey Richard,
You can find the lampsocket here: http://shop.van-eck.net/lamps/lamp-sockets/p-1a/LV-0002.html
If you got either a soldering iron or a thermoplastic connector you can fix it yourself

You can make a join with a block connector but if you are a stickler you might want to replace the cable back to the soldering point.
