I've had this TV for a month now, so I can not speak for it's reliability yet, but I can say that I am totally pleased with this TV so far. I comparison shopped for a couple of weeks before deciding on the 46XV545U. This TV was the best value and had the most bells and whistles for the money hands down. The picture is stunning in HD, BluRay and DVD's and I can even say standard def TV is not too bad either, although once you watch HD it is hard too settle for standard def. It's multi unit remote is well laid out and is now the only remote I use for my whole system, it runs the TV plus 3 other devices. It takes about 4 seconds for the TV to turn on and from what I've been reading that's in a pretty good range. The TV's menus are easy too navigate and well laid out. There are 6 picture mode settings - Auto View, Sports, Standard, Movie, PC, and user preference, the TV will remember which setting you have for each device which brings me to my only complaint so far, there is only one user preference setting so if you want to tweak the sports mode a little bit then that will be your user setting, then if you tweak the movie setting then that becomes the user setting and you lose the tweaked sports setting, although I liked the factory settings I would like to tweak each setting a little so 5 user preference spots would have been ideal, all in all not a big deal but it is something worth knowing about. This TV has plenty of inputs and I have tried them all, one thing worth metioning is the VGA D-Sub PC input can only handle the following settings: 640x480, 800x600, 1024x768, 1280x768, 1360x768 and 1280x1024. I hooked up my PC through the HDMI input and it was stellar at full 1080p resolution. The sound from this TV was more than exceptable but I have surround sound so I do not use the TV speakers.
I choose not to buy the extended warrenty after reading reviews on them. you get 1 year manufacter warrenty and my credit card covers the second year for free so it was not worth the extra money to get a third or fourth year of coverage, so I hope this TV will last!
Delivery took one week, and I bought direct from Amazon with the "white glove" delivery. They can unpack the TV and take away the box, but I reccomend keeping the box in case any returns are needed. I had this TV unpacked and setup in less than 15 minutes.
In summation, I think you will not find a better TV for a little over $1600 bucks that has all the features of this one. As long as this TV does not break down I will be very happy with my purchase.
