I received a Projector from a friend December of 2010. It is a Sharp D100U from 1997. It did not have the original bulb, but everything else worked fine. I did some research online to see if I could get a bulb for it and found out that it would cost me $300. I could buy a reasonable projector new for that much. All I really needed was a new light source, so I thought a high-powered LED would work great. Rammstein Made In Germany Rar.

There were two stages to this project. The first was figuring out how to bypass the bulb checking circuit, and the second was building the new LED light source. I found these two Instructables by to be very helpful with this project: UPDATE! I found the maintenance manual for this projector http://diagramas.diagramasde.com/otros/Manual%20MAINT.pdf.

The first thing that I wanted to do before I started taking the projector apart was to see how it currently ran. I plugged it in and turned it on. The fans came on and I could hear the sound of the fans and a faint ticking sound. Along with two green lights that indicated Power and Bulb. After about 3 seconds the bulb status light started to blink, and after about 5 minutes the projector shut off and both lights turned red. I shut off the main power switch the red lights turned off.

I then repeated that process a second and third time to ensure consistency. I did some research online to try and find any documentation on the projector. All I was able to find was the user manual. Reading it I found the section that addressed the indicators: Power, Bulb, Temperature. There are three possible states for each indicator: Solid Green, which indicates Normal operation; Blinking Green, which indicates Starting up; and Solid Red, which indicates a problem. I removed the top case and accessed the main logic board.

My intent was to find the logic signal that was telling the the board that there was a problem with the bulb. I used my multimeter with the ground connected to a grounding point on the projector and started measuring values of all the wires going to the main logic board.

I was lucky to find that each set of wires was labeled, but it was only abbreviations. After I recorded all the wires in each state, I made some assumptions as to what each set of wires went to.

I did some more research and found that some projectors use optocouplers which are used to measure the feed back from the bulb (see the photo for a full illustration of how one works). I gathered from my research that I had to bridge the optocoupler that controlled that bulb to trick into thinking that it was working fine. I started to dissemble the projector even more; all the way down to the power supply.

I found the three ICs that I thought were the optocouplers and through trial, error, and almost bricking the whole projector I was right back where I started. The projector sat in pieces on a shelf for a couple of months while I was busy with school and other things. I came back to it in the summer and tried again. I reassembled it and tried to figure it out with more research and more trial and error.

I was able to get the high voltage arc to stop by unplugging the BL cable from the main board, so I was starting go get some where. Once again, the projector sat on a shelf until December.

Just when I was about to tear it apart and use it for parts, I decided to give it one last try. I focused on the main logic board.
