Engineer turned up with replacement #2 today and I've checked the image through with my AVCHD disc and it seems fine. The unit is just as quiet as the original, so far so good. In fact the pixel convergence (or alignment) is spot on on this unit right across the image, which is better than my original one. Apparently if any issues occur with this one I can call it in in the same way as the original unit. The engineer mentioned one chap he'd been out to was on his sixth unit in as many months, but now they were swapping his TW3200 for a different model altogether! Can't fault Epson's response times - only a couple of days from raising the fault to the problem being resolved.
