I currently have a Samsung LN-T5265F (52" Samsung LCD) and it is starting to drive me nuts. It has over time developed an issue that upon initial turn-on after being cool for a while, it "tries to turn on" multiple times before finally being successful. If you have the power on sound enabled, it plays it every time it tries to turn on. After 4 or 5 tries, it finally manages to turn on. Sometimes after the power it on though, I get what I can best describe as "live pixels" (rather than dead pixels) that are stuck white at random parts on the screen that look like stars. All I have to do is turn it off and turn it back on and the problem usually resolves itself.
Most of what I have read about this has hinted at a power supply problem, but I'm considering replacing it with either the UN55B8000 or the 8500, and I'm pretty torn. I have read the forums and my hesitance on the 8000 is the fact that it's edge lit and the issues with clouding and light / dark edges has me a little spooked. It seems that some people report it being a huge issue on multiple models they have purchased (after replacing one 8000 with another 8000) and others report no issues and resounding happiness with the set. I don't know if the people reporting no issues either don't know what they're looking for or aren't picky enough to care that it exists. I realize that the 8500 is a back lit display with local dimming that would prevent this, but the premium over the price of the 8000 is a little hard to swallow if the concerns with the 8000 are less common than what complaints would suggest (the "squeaky wheel gets the grease" phenomenon).
Now I know people are going to suggest Plasma, but I'm a fan of LCDs mainly because of their power draw. While I'm no tree hugger by any means, when I was shopping around for the purchase of my 45" Aquos (which is still alive and kicking in our bedroom by the way), the power consumption of the LCD was almost half that of its plasma contender of choice. I ultimately chose it based on power consumption and the fact that the higher end LCDs had better blacks than the lower quality LCDs. I would still like to stick with a lower power device (which is one thing I like about the Samsung LED TVs), but the slimness of the LED TVs is something I find very attractive as I think it adds a sense of class to the room. Say what you want about aesthetics, but anyone who tells you it's not important is lying. Low on the priority list? Perhaps - but it's still important.
Is my reticence regarding the 8000 unfounded? Should I spring for the 8500? Or is there perhaps something else I'm not considering?
Sorry for the long post. I appreciate any insight, suggestions, and / or recommendations. Thanks for sticking with me this far. Punch and pie will now be served in the reception room.
