DLP Rear Projection TV Teardown + Analysis & How It Works

Opening a rare and expensive DLP tv to look at its parts and investigate how it works. This is one of the most sophisticated TVs I've ever taken apart.
There is an insane amount of complex video processing going on. I can't even imagine the software side of things. Each one of the videos processing chips must be running a TON of code, hence the huge amount of Dram. This tv had a MSRP of $4,700 USD back in the day! ($7,200 in today's money)
