Tricking projetor to accept bulb
I found a sharp xv-zw99u tv projector in the dumpster. It was thrown out because it need a new lamp. I saw why after pricing them! I built a new holagen bulb for it with 300w 120 v bulb. I know they get hot so I will keep an eye on that. Heres my problem, the lite works for one second and something clicks and the light goes out, and if I keep the machine on, the lite will relite for 1 second about every 30 seconds. I read your emails to Kahurt on other site, and he has the same unit I have. I need to know how to trick the machine to accept my homemade bulb. I think I have the four wire unit. I was wondering if you figured out how to trick the four wire unit? Your help would be greatly appreciated. Thaks Matt

I have an old Sharpvision XV-H37U and am just wondering if you ever figured out a way to trick on of these. Not sure which bulb option I will use at this point but want to know if anyone else has had any success that they may share with me.
Any and all information will be greatly appreciated.

I knows this is really old but hey if you are still around This is what you have to do. jump the 2 middle brown wires and thats all there is to it. You probably have a switch where the bulb goes so you will have to make sure that switch is closed. I guess this can help other people to. 🙂
