Spoofing in a new lamp.
Alright so I need help to fake logic one on the main board so my jury rigged bulb will work. It's a classic story, old bulb burnt out and they are way to expensive, so I built my own but the dang projector knows that I don't have a normal bulb in it and so it shuts the image off after 30-ish seconds. Here is a picture of the optocouplers right in the power supply. Any help as to what wires I should solder together.

you have to connect both leads of the most leftwards optocoupler , the one that looks upside down considering the other two , link the two legs that go to the connector and the projector will work , because this opto tells the motherboard there is a current passing through the electronic ballast or else there is a working bulb installed
