Sanyo Projector Teardown

So a few weeks ago I managed to get my hands on a Sanyo PLC-WXU700A for free. I tried getting it to work but the warning light would light up and the projector would just shut down. I was pretty sure it was fixable but I didn’t really need a projector anyway so I left it in my room for disassembly in the future.

Well, today was the day. I didn’t expect to be impressed by what was inside, but I was.

Interestingly, it seems like the pads around the screw hole are connected to ground.

Projector optical assembly (bulb, mirrors/lenses, LCDs)

I actually didn’t know how a projector worked until I took this one apart. When I saw the three LCDs screens and looked at the orientation of all the mirrors, I guessed that each of the LCDs was responsibly for one colour. Shining a light through the lens confirmed my suspicions.

I was going to take the lens off the apparatus but I decided that this was simply too cool to take apart.
