OOW=Out of Warranty
Contact technical support. For Optoma OOW repairs call
888-942-2929. Calmly explain that you know the white
dot problem is rampant, that you know that these failures
are being handled out-of-warranty, and that you'd like to
have your unit handled similarly. (For the record--never,
never get irate with a phone CSR. You get much more with
sugar than you do with salt.) Mine was given a green light
after a five phone hold. "Okay, but just this once...."
A little research will show you that Texas Instruments is
the primary manufacturer of the DMDs. They license other
companies to sell their devices in their rebranded units. So
any white dot problem can be handled the same way with
any other company. Be patient, but be firm. Never be afraid
to calmly ask to speak to a supervisor when you don't receive
the answer you're expecting.
