DIY replacement lamp for projector

[mattystar]

O.k I will have to gp pick it up from my moms, but I will be sure to post pics. So what do you think about the light n reflectors.

Can you not use your existing relector from your original lamp? HID Xenons are the next best thing although a bit dimmer on increased screen sizes.

No, because I bought it without the bulb and reflector. Also I can't seem to find where to short it to get pass the bulb check. Hope these pics give you an idea.

Hey again, I went at it some more and found the basalst and removed it. Found the 3 wires. In my case it seems to me typical to colour. Red 5v, Black ground, and Yellow standby. Now I know I have to short the 5v to ground with a 5v resistor, but what about the standby? Also I heard someone went to home depo and bought a work light and used that with its basalst. Worked great apparantly. I seem set but I thought it would be helpful for you guys.

Hi All:
My projector is [SHARP XR-11XC]
1.
I try to link the Emitter pin and Collector pin together of the PHOTOCOUPLER (I think it's PC123Y) like picture 01.jpg, and it work!! It will not show "LAMP OFF" anymore! But......
It shows "Warming Up, Please Wait...", and after few minutes...it turn off! @.@|||
2.
There is two components outside the lamp housing in picture 02.jpg which might relate to "Warming up" sensing I guess.
The close-up pictures are 03.jpg and 04.jpg.
Does anyone knowes how to solve this situation?
Thanks
PS: I am sorry for the poor english. T.T

Pic 3 seems like a thermistor. If it is then it is likely to be a PTC type where the resistance increases with the temperature. I don't think that the thermistor has anything to do with the projector not staying on after shunting the photocoupler. It is purely temperature related. Pic 04, you may need to take it off and show it in more detail. Somehow I feel you may be shunting the incorrect photocoupler.

Thank You Gizmotech.
You are right! I was wrong!
There is another PHOTOCOUPLER (PC123Y) somewhere else. It setting on a narrow space that i can't take picture. This one is the correct PHOTOCOUPLER! So my problem now is to put a suit lamp in. It's really diffical to find this suit lamp....I'm still searching for the lamp!
Did anyone have idea about a lamp bright enough and cheap enough and easy to use for the projector? If the lamp use 110V will be most convenient, because it need no adaptor.
Thank you again!
