Question Who can diagnose this (horizontal bars)?


Novice Member
After replacing the bulb (w case) and cleaning the interior I get this really weird issue with my w1070 benq projector: picture is divided in 14 equal sized horizontal bars - each second bar is fine, the rest have big color issues (see picture):


I've double checked all connections but don't find any errors or loose cables. Issue is with both HDMI ports and VGA. Did I break something? Can't find anyone with this particular problem after searching everywhere. Diagnosis much appreciated.

Thx for your feedback. It's the same on the projector menus, so internal error, not related to input signal as such. I didn't remove the color wheel, but took out and cleaned the DMD.
