Building was hit by lightning, projectors are dead. No lights. Is there a fusable link or some other easy fix?
This unit uses a DC to DC converter, and it is very sensitive to voltage spikes, it does have a fuse on the power supply and it also has 4 solid states fuses that look like transistors and resistors on the power supply board.

For me, it was the video cable from the PC to the projector. You have to store these cables gently and don't bend the cable sharply, especially near the connector. Grab a video cable from an older style PC monitor and give it a whirl. Good luck!

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.)
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.
