Sorry to resurrect a very old thread, but my 6500UB just started giving me a magenta bar at the top, and a cyan bar at the bottom. They appear even in the built in test pattern, so the issue is internal to the projector.
I'm now out of warranty on the PJ, so I'm concerned about the repair cost. I haven't even gone through one lamp yet!
I've googled this issue, but can't find any explanation of the problem, or how it might be fixed (either DIY or by a service center). Any ideas?
Thanks in advance!
