Check this pic :
You have to find the same place on your ballast, the 3 black squares on the left.
Take a pic of this part, then put it here.

Lorsque j'appuie sur buton alimentation, les ventilateurs commencent à courir, feu rouge clignote, et rien afficher sur l'écran, le projecteur ne s'est pas arrêté.

Thanks for the pics, very helpful.
Well ok, check this one :
To bypass the "lamp is here" check, the shunt must be on the top left one.
The short will be on the pins which are the closest of the wire connector, see below :
Then, connect all parts, close the VP, switch the power on, and check how the things are running :)
Note : all wires should be connected like as factory default.
Note 2 : take care about security systems if you don't close the whole projector.

You are welcome :)
Did you tried to connect some video device on the VP after the shunt ?
Try to start a movie, and watch if infocus logo will disappears.
Hmmm...the shunt we just made is for bypassing the "is there a lamp" check.
With it in place, the VP do the same if there is or not a working lamp installed.
I thought this is what you asked for.  :jap:

Oops !
Yeah, right, it's a DLP projector, so there is a light sensor also.
What you can try for now :
- leave the shunt in place,
- find some kind of lamp like this :
Put it in the VP as a replacement of the original lamp (you can use an ATX PSU as power source).  
With a little luck, this will fool the sensor and the VP will fire :)
Note : on my LP130, I tried first a 12 V 20 W and that was not enough to fool the sensor.
So, another try with a 50 W model made the trick.
REMEMBER : do not try to connect it to the ballast  :)

I agree with that. We need help.
What do you mean by "take out the whole housing" ? Is it the factory bulb ?
Je resume rapidement :
Je lui ai fait shunter l'opto sur ma photo, il a essayé une dichro 50 W.
Il branche, il entend du bruit, pas de loupiote rouge en vue, juste
la verte qui clignote.
Et il se passe rien d'autre, meme en branchant une source à l'entrée.
Là, je sèche, on a besoin d'aide !!!  :)

Wait a minute !
You have LP530 and you are talking about a LP630...
On your own pictures, the optos are black and Andredenis has white ones.
Yours are located on the ballast, and it looks like his are on the motherboard.
I advise to not try the same as him, but the ending choice remains yours.

Posté le 16-01-2011 à 11:16:16  profilanswer

Yeah yeah...your right,mmine is LP630,not like Andredenis...just thinking that on that Infocus model he make a second shunt on the motherbord,i wondering what he sunt,may be mine olso need another shunt...thats it...i dont know abouth that light sensor,i didnt see anything like a sensor in the tunel.May be VP is waiting more bright light than my 50W lamp to stay on...!? :??: Thank you for staying with me on that mr.HarFanG.Have a nice day
edit:I just see somewhere on te net that some light sensors need just light,other to be shortet to ground other to voltage
