One of my two Elmo GS1200, main motor is not running!
I found the cause of the failure that comes from one of the transistors marked by the arrow on my picture!
Someone can give me the reference of these transistors and where can I get them?

I am thinking in particular of Ugo that has fully restored one of these projectors

Thank you very much

Antoine,

While you have the machine apart, you may as well replace all of the transistors of this type.

They are all alike, and have been operating in the same environment, and probably doing the same thing.

So the one that failed is probably just the first to go, and not the last.

(Just like light bulbs in a chandelier!)

Thank you very much to all those who replied.
I easily found in France the BD241C.
It is not me who will repair my projector, I am not able.
I have a friend who is going to do. When I told him that I had found the BD241C, here's his response:
"it is not worth the bd241c they have in stock"
but it is of small differences in operating voltage
If one replaces a transistor by equivalency
need to replace the entire chain of transistor that works together"
This is what seems to also say Steve.
Thank you all once again

Steve's right. Do one, you may as well do them all with the same while you're in there.

This forum is great. We receive help from serious and competent members. I warmly thank. Unfortunately I do not write as I would in English and I spend every time by a web translator. The translation is not famous but I hope I can make myself understood

My friend was able to repair my projector Elmo GS1200. There's much damage at the level of the electronics. Now it runs very well.
I'll give him another projector GS1200, the motor begins to run 4 minutes after switching on the projector and the reverse does not work! Maybe a relay problem?
