Bypassing lamp detection circuitry

[bea]

Hi everyone,

I'm having a problem with my video projector. The lamp went off, I want to replace it with a pcb with LEDS. The problem is that I need to bypass the lamp detection circuitry so that my new lamp can work with the motherboard. I know I have to cut off two wires and connect two others to bypass the detection,I think it's the yellow or the blue one ( on the 2nd picture, the one removed). But I 'm not sure.... My projector is a canon sx6. Here's some picture of it. If anyone could give some help, it would be fantastic. Thx a lot.

Hi Bea,

A circuit diagram or block diagram of the unit would help. If not available, can you remove the lamp assembly and post some pictures of the wiring to it?

I would think that brightness level and over temperature is all that is monitored at the lamp assembly and the current drawn by the lamp is monitored on the main PCB.
