Broken flat screen TVs DO have value (way too much in my opinion). Even ones with bad screen burn seem to go for as much as 50% of their new cost. I've been trying to get my hands on some dead plasmas to play with for a couple of years, but they don't seem to be available for less than a small fortune. I bought one on ebay, but it was smashed by UPS.
