Replace Projector Lamp with LED

The very first thing that I wanted to accomplish before I began taking the projector apart was to observe it presently went. I plugged it in and turned it on. The followers arrived on and I also could hear the noise associated with followers and a faint ticking noise. along side two green lights that suggested energy and Bulb. After about 3 moments the light bulb status light started to blink, and after about five minutes the projector shut off and both lights switched red. We shut off the key on / off switch the purple lights deterred. When I repeated that procedure a moment and 3rd time for you to make sure consistency.

I did some research online to get a hold of any documents from the projector. All I happened to be able to find was the consumer handbook. Reading it I found the area that resolved the signs: energy, Bulb, Temperature. You can find three feasible says for each signal: Solid Green, which indicates regular procedure; Blinking Green, which shows Starting up; and sound Red, which suggests problematic.

I removed the most notable situation and accessed the key logic board. My intention would be to discover logic signal that has been telling the the board there was an issue because of the light bulb.

We used my multimeter because of the ground linked to a grounding point-on the projector and began calculating values of all the cables visiting the main reasoning board.

I was lucky to locate that each and every pair of wires ended up being labeled, nonetheless it was only abbreviations. When I recorded all the cables in each condition, I made some assumptions as to what each set of cables visited.

RC - Remote control (Since i didn't have a remote the projector and didn't want to buy one I eliminated this wire and sensor)

BL - High voltage and lamp check circuit ( this is actually the wire set that At long last figured out ended up being the only we needed to concentrate on )

LF - Bottom fan cover sensor ( The two wires with this connector must be cut and tied together if you wish to be able to operate the projector with out the fan address )

FF - Fan

LL - Lamp address sensor ( both cables on this connector should be cut and tied together if you'd like to manage to run the projector with out the lamp cover )

Q - Temperature sensor

FN - Fan

There clearly was also a couple of colored wires in a single connector that In addition recorded, but these wound up not needed to alter the projector.
