[j] sent in this nice writeup on how to. He managed to pick one up for $20 that had a broken bulb. While the prices of bulbs have come down considerably, they can still be a couple hundred dollars. Being resourceful, he decide to just use a halogen bulb that he picked up at his local big box shop. In the photos, he’s using a 50w mr16 bulb. The results really aren’t too bad. Especially considering that his cost for the entire project is now roughly $25. He does, however suggest that a 100 watt bulb wouldn’t be a bad investment. His projector seems to need some cleaning and adjustment in the lenses as well, but for $25 it isn’t too shabby. We’ve had this submission for a bit, but it didn’t have any pictures of the projector actually working. During our conversation, we may have possibly suggested a picture we’d like to see. You can find it after the break. We did cover a very similar one last year, which had the, but the project page seems to be gone. There is also the possibility that the projector you get doesn’t just have a bulb problem. Sometimes it is the. Posted in, Tagged, Post navigation. For those looking to “trick” a projector into thinking that the bulb is still there, so you can replace it with a cheaper setup, this is the “famous” post on diyaudio that discusses the issue. Essentially, the ballast has a logic line that indicates if the bulb is lit. This video was uploaded from an Android phone. In the case of the link, tying it straight to ground (on the safe side of the opto) forced the unit into thinking the bulb was always lit. I’ve been thinking about doing this to a 3LCD project I got for free, with a blown bulb & ballast, and retrofitting 100W worth of high power LEDs in it’s place. @nubie “Nice, also you can replace a DLP color wheel if necessary.” Did a quick search of the article but did not find the word “color”. Please more info on color wheel replacement – especially where to get parts! Have a very expensive projector sitting here with a dead color wheel and I’m too lazy to drive the 40 miles to the nearest authorized repair facility. Don’t buy InFocus – their customer support sucks (for the consumer) and the two InFocus products that I have purchased made it through the first bulb and died on the second bulb.

Their customer support was absolutely uninterested. @dave Yerp, both InFocus projectors blew their lamps – *pop* – run for the mercury free zone! On one the color wheel is completely dead – vibrates real bad on startup and sometimes gives really whacked video, most of the time it refuses to fire up. The second, a 4805 as well, popped a bulb and now about%10 of the projected image on the right side is “dim”. Ok for SD but sucky for HD. And worst of all the InFocus support folks neglected to return my emails and when I called they were rude and did not care that they were losing a customer. ![]() @nubie – thanks! I just never thought replacing the color wheel was something that a user could do (special tools, etc.). I took this one into a non certified local repair guy and he serviced it but could not do the color wheel as he had no source for parts (not being an official InFocus repair guy). I’ll take a look online though! Thinking of replacing the InFocus projectors – can anyone recommend a bullet proof, well supported, awesome looking “full resolution” HD projector? Mata mansa devi.

Googfan is right, it would be very very yellow. Color temp is measured in degrees Kelvin, a halogen bulb is 3-4,000 and white is somewhere around 5,500, so you want to get a good bulb, you can put in another Discharge lamp for $30-100, I would look that direction. @ Greg: I know that there is also a laser DLP that looks very interesting to me, I don’t know if LED or Laser is better, but either do away with the bulb and the color wheel. I think Mitsubishi has some Laser DLP rear-projection TV’s out now. Before large LCD’s and thin TV’s were really on the market I built a projection television cheap. I should say I had help building one. It involved an overhead projector like you see in high schools. I picked one up off eBay that got modified to use a light from Home Depot. Cut a hole in the side for a fan to get rid of some of the heat the new bulb made. Similar to something like this: Then I bought a cheap InFocus LCD projection panel off eBay for under $50. Looked similar to this: So, whatever is displayed on that panel gets projected on the wall. Kind of bulky, kind of ugly, but was cheap and huge. I have done approximately the same thing with a DLP, except the bulb I chose was from an overhead projector (the type high school math teachers love).
