i get a dust blob on my new sanyo z1 after 3 days of use, its a nasty one about 6" in diameter. right dab in the middle slightly off center. So far no help from Sanyo, Ive called their LCD projector line at their head quarters a few times and NO ONE EVER ANSWERS THE PHONE... NEVER... its always an answer machine and asks for my name and number so they can call back.. THEY NEVER CALL BACK EVEN AFTER MULTIPLE PHONE CALLS. then the reseller gave me a number to call aside from sanyo, so i call them, supposedly they handle all sanyo warranty repairs... i call the first time NO ANSWER, so i leave a message... two days later i get a call from them while I was at work on my answer machine asking to call them back, I call them back... NO ANSWER, I leave another message and NEVER RECEIVE AN ANSWER... These guys are a joke, Has anyone ever had Sanyo honor their warranty? because so far they dont seem to be very helpful.
