Hello,


The small 4cm fan on my 1270 just failed

and I replaced it with a new one.


The original fan has 3 wires (black, yellow, red), which would mean (ground, sense, power).


The new fan has 2 wires (black, red), (ground, power).


I connected the black to black and red to red, but I'm not sure what I have to do with de yellow/sense wire.


I tried shorting the sense wire with the ground wire, but the projector will shut down imediatly (BTW where is that display with the error code?)

When I don't connect the sense wire to anything it works, weird.

The Pj should work after grounding the sensor, the error display is on the left side if Pj is on the floor. Put the yellow and black together then it should work, do for me anyway.

As I said if I put the yellow and black together it doesn't work, if I leave the yellow disconnected it will work.


I guess the display is not in the 1270, cause I asked someone where it should be located. On the side near the coils of the red tube, but I just have a hole there, watching straight to the coils.
