I sent a mail today to an online PJ retailer enquiring about whether they could do a dead pixel check for me before purchasing (at my expense of course). They said they'd look into Epson's policy on this PJ and assuming all was well, they'd be able to help. I've just heard back that Epson will only guarantee 99.99% of all pixels. That just leaves 0.01%, which on a TW100 is something like 1280 x 720 = 921,600 * 0.0001 (allowed defective pixels) = 92 * 3 (three panels) = ~276 pixels Or if you ignore the 3 panels, then its still 92! Here's the Epson blurb (from the retailer) on the subject (my emphasis): "During projection, some points (dots) may appear lit at all times, or they may be dark at all times. This is caused by the characteristics of the LCD panel, and is not a sign of a malfunction. The LCD panel is manufactured using an extremely high level of precision technology, however 0.01% or less of the pixels may be missing or appear bright all the time." You're 'avin a laff! Also, see here for a previous thread on the subject of the TW100 & dead pixels in particular.
