Question about Hitachi PJTX100 Multimedia Projector
Blue patch from top to bottom on left side of screen
I had the same problem with my Hitachi PJTX100. I discovered that there was considerable dust build-up inside the unit, causing insufficient venting of heat which then damaged the color prism/filter. It was close enough in time to the warranty for Hitachi to cover parts replacement (approximately $1,600). Since the repair, the blue patch is gone. I also regularly vacuum not only the outer cover but also the inner air filter that easily snaps on and off.
