Would a mod mind moving this as it seems we cannot post in QOTD anymore. Since this is a bit tougher than most... perhaps students and people that aren't professional projectionist for the first week would make more sense? This is a 3 chip DLP projector thats unhappy. Image 1 shows what should be a black and white checkerboard test pattern with a menu on top Image 2 shows a black internal test pattern with a menu on top 1. Whats missing? 2. Whats there that shouldn't be? 3. What part is causing this problem? 4. Where would you (if you were going to be working on it) start looking? Note: I've already fixed this so this isn't a help me thread. I just thought it was kinda interesting and would give people an interesting challenge. Theres a bit more to this that I will post in a few days but it gives away answers to these questions.
