It's caused by too much correction. Try reducing keystone. The best approach is to properly set up the projector. This has been covered lots of times before. A quick search will reveal various threads and answers to this issue. There's nothing wrong with the projector, you are just pushing it a bit too much.
MAN it must be pushed very hard because I have messed with mine to the extreams and have never seen that one !
Yea, I support TINMANS assesment, these machines are rock solid if they are set up correctly from the get go. I never took much time with my first 1031Q and it needed constant attention. I retubed my second unit and it is now MINT all around. After retubing I had no choice but to set everything up 100% and now the results speak for them self!
Check and recheck that you are at the correct throw and the screen is at the right position for the deflection angle so that you are not pushing keystone to the max!
what's up?i can tell you don't feel bad,i too had this problem...i was messing with pots and next thing i know it was there...i wish i remembered exactly what pot it was i turned to fix it,but i dont...it CAN be resolved with no problems though..
p.s. the pot if i recall was on the convergence board,it was not a convergence pot for RGB...i don't think...beleive it was too the top of the white plastic that surrounds the convergence pots...
