After reading a lot of horror posts on this thread, I thought I'd chime in and tell everyone about my experience with the set.
I've had it almost exactly 1 year and 3 months now, and every day with it, we still marvel in it's beauty and performance, especially with HD content... Minus one minute.
One day, when turning it on to watch a DVD, we had the very strange blue-ish pixelation occured. My wife called me in to ask what was going on, and I hadn't a clue - I thought our DVD was going on the fritz, but I did recall the post earlier in this thread with screen shots, and my heart dropped. I thought it was the start of the end. I tried different sources with different inputs, and it didn't help. This happened 1 month after the end of the warranty - we did not purchase extended warranty, as we're not a fan of those generally. Anyway, I turned everything off and unplugged the tv from the bottom, left it for a few seconds, to ensure all the power was drained, then plugged it in and retried... and to my delight the blue pixelation was gone, and hasn't been back since. Hopefully this was a one-time thing and never happens again!
We've recently purchased a Playstation 3, and watched a few Blu-Ray movies on it (in 1080i mode), and WOW, what a sight!! I can only imagine how the newer 1080p sets look (from what I've read, not much different, though).
I still worry about burn-in while in the PS3 menus and games, but so far it hasn't been an issue. In my paranoia, I've turned down the brightness and contrast a little which are now at around 45 each -- But these settings seem too dark and I seem to be losing a lot of detail. I need to spend some time with the settings and with my DVD Essentials to re-calibrate.
To speak on Philips Customer Service, I have yet to deal with the electronics dept, but I have dealt with the lighting division (what Philips is known for), and that experience was top notch - the best I've ever had. I had a transformer from an LED deck lights kit blow on me, and they sent out a new one, no questions asked, paid for shipping, no receipt necessary, no serial number needed, no need to return the defective unit.... in fact, there was no way they could have known that I had even bought the thing. Because of that experience, I can only assume that I'll have good experiences with them if I ever need to again for other departments. Maybe I just lucked out, or because I'm in Canada with different customer service centres? Who knows?
But for anyone reading this thread, let it be known that the good sets FAR outweigh the troublesome sets. I feel for those with problems, but unfortunately you just got bad luck with buying a lemon.
