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.
Fans for cooling the projector bulb
Here you can see the heatsink that encloses the bulb
Interestingly, it seems like the pads around the screw hole are connected to ground.
Looking underneath the main PCB
It seems like the metal enclosure is grounded
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.
