Lightbulb How to control a eballast from IBM projector in a JVC projector ?

Hi everybody,
First, sorry for my english... I hope you'll understand me

I have a JVC DLA-G10E projector, with original lamp dead.
I need to put an UHP (SHP) bulb into the reflector for replacing the very hot (and very expensive) 400w xenon lamp.

So, I bought a IBM iLC200 to take his eballast and put it on JVC projector. With 280w UHP bulb, it will be good.

But...
I think the e-ballast controller signal and voltage are not the same between JVC and IBM.

This is the block diagram from Service manual of IBM iLC200 :

And this is an image of JVC diagram :

(bypass = "SW5VRST" + "LAMPRET")

A suggestion ?
Please...

Can you tell me if I'd asked for some help in wrong section ?

Bye !
