As some of you may or may not be aware I am on my second 9986. The first was v1.3 the second is v2.1. This was for a good reason. . . . I have a Tosh 340 with component PAL prog and have to have v2.1 for this to work via DVI. So what is the problem. . . . . on the v2.1 I have the hum when the contrast is below 98 (by the way this does not happen from cold, it takes a few moments before the hum starts) and the intelligent lighting hardly works. On the v1.3 there was no contrast hum and the intelligent lighting worked perfectly. This is an amazing set when it comes to picture quality and even the sound quality is quite good, but the build quality and the quality of components and features is absolutely shocking. Why do we put up with this stuff? Ian.
