Hi everyone, long time lurker, but first time poster.
I am having an extremely difficult time accurately judging the F8500 at the stores (tons of bright lights, and the damn thing is surrounded by ultrabright LEDs). So the F8500 ends up looking like crap by comparison. I want the best picture quality possible and I need some reassurance that this thing stands up well to decently-lit living rooms (Typical house with a few windows and some decent blinds).
How's the viewing experience in the middle of the day in your living room? Will I miss my bright and punch LED?
At best buy, the difference between any LED and the F8500 is staggering. I asked the kid if I could have the remote to fine tune the brightness (thinking i'd try to even the playing field). He said he doesn't really know where the remote was. I'm surely telling you what you already know, but Best Buy isn't a place that lets you get particular. The plasma was also wedged closely to the back of a set of theater chairs, so there was no comfortable place to view it. I'm hoping Fry's in Austin has one I can see. It sounds like the F8500 got a very unfair shake for comparison. Thank you.
I just bought a Samsung PN64F8500, since the prices on the Panasonic plasmas went through the roof -- the Samsung can't be that much worse, could it? (that was a joke!). I'm a bit of a videophile, but I'm a bigger cheapskate, so it will be 10-14 days to get here since I've too cheap to pay for expedited shipping (picking up on that theme?), and I need to get some stuff arranged for it. I have a rather large inset where it needs to go, so I can't [practically] wall mount it because it would be too deep to see off-angle; it also makes it so that it really isn't set up to be mounted on a stand either since the panel really should be flush with the outer plane of the inset. What I'd like to do is hang it from the top of the inset so that the panel is flush with the cabinet facing. Has anyone tried to hang their panel? If so how did you do it -- did you modify the wall mount?
The inset is part of my built-in cabinets, which span the width of my family room (It can't be moved). The inset is 23 inches deep (back of inset to front plane of the cabinet facing), 64 inches wide, and 62 inches high (floor to top of cabinet inset). The house was built back when projection TVs needed to be a little deeper to be installed. The top of the inset, which is part of the cabinet is substantial, and would easily support two load points of less than 50Lb each (weight of the panel/ two pick-up points). What I'm thinking right now is to build a cabinet that slides into the bottom of the inset which is 24 inches high (or so). I suppose I could just put the TV on the lower cabinet, but was thinking two things: 1) I'd like the TV to be flush with the outside, and I'd like the panel to be centered in the hole (aesthetically speaking). I was figuring the easiest way to do that was to suspend the panel from above. I suppose, I could just set the panel on the lower cabinet, and I may yet do that, but the panel would no longer be flush then. Maybe I'll start out that way and hang it if I don't like it.
I know you were joking...but seriously...I love the Samsung F8500 far more than the Panasonic ZT60 it replaced. Much better picture, I think.
Exactly. The F8500 is a torch. Very bright. Very sharp. Fantastic Black Levels.
I was thinking about that. It is NOT open; however, there will be a 3 inch gap at the top, and a 3 inch gap on either side. The stand doesn't leave much of a gap at the bottom when installed, though if I hung it that area would be clear to draw air in at the bottom. I suspect that this won't be enough cooling though, but the suspended condition would be better than the stand. Still, my guess is it won't be enough. I would hope I could find some REALLY quiet fans to install there. I wonder how many I've going to need, or in other words how much air I would need to move. Additionally, with regard to fan noise, questions come to mind such as would it be better to run 3 fans at 1/3-1/2 power or 1 fan at full power. How do you throttle the fans anyway? Is there a USB on the TV that would support a fan? I would think most of them are run off a computer power supply. I am VERY open to input on this topic! Anyone done that and been happy with their setup?
I was joking -- even mocking if you will, some of the craziness. I used to be heavily into audio, and it was the same thing. People would get so wound up about stuff, but in the end, your mind is a pretty powerful device for compensating when things aren't ideal. Wear a pair of amber goggles (or dark tinted ones for that matter) around for an hour and then take them off! It's kind of freakish as you mind has already started to compensate for the tint! That's why you have to put the panels side-by-side because the difference IS very subtle! I think your brain has the ability to adjust to the panel output. It's been shown over and over that psycho -acoustics is as big of a deal with regard to how sound is perceived as ACTUAL acoustics! I think it is the same with vision (of course there are always a few exceptions -- individuals that really have the ability to perceive the difference, but I suspect that they are a very small percentage -- even among those that are 'serious' about it). So plug in and enjoy -- they are all very good (and certainly to my mind the Panasonic is not worth $900 more bucks!)!
I'm an engineer, and I will give you kudos for a nice solution given a very difficult problem. That certainly gives me a couple of ideas! Any tips on which fans might be quiet, yet move sufficient air?
I found this fan:
Noctua 140 mm NF-A14 ULN, which is supposed to be very quiet. 140 mm so it can move some air without being noisy. I was thinking to get 4 of them.
I also found this controller:
Silenx External 4 Channel Fan Controller with AC \ DC Adapter, which can power 4 fans.
However, I think the fan comes with some resistors so that you can set the speed level (low level is quieter), So I think I could get by with a power supply rather than a controller, but I wouldn't need a high-powered on such as a PC power supply, so I'm not sure where to get it. I think I will order the fans and then work on the power supply. Any suggestions? or just go with the controller? One dude says that he actually uses it for his audio system cooling, but stated that he has to replace it about once a year because it's a bit wimpy...
Does the Samsung panel have a switched 110V power output?
Keep in mind, I'm not saying brighter is better. I am, however, saying that it's very hard to appreciate a plasma screen when surrounded by bright punchy LEDs. I tend to go for the girl-next-door types, but if you stick one of them in a group of Sports Illustrated swimsuit models, it might be tough to appreciate her. That's why this particular Best Buy wasn't doing Samsung's plasma any favors.
I really think you're on the mark about the plasmas. I think I will enjoy the F8500 much more than a comparable LED, and unless my living room is a greenhouse I don't think I'll have any issues.
What do you use as your power source/transformer for the fans. Which thermal switch did you use, and how did you wire it all together -- I guess at temp it closes, so they are 'on' all the time, but the circuit only closes when it gets at temperature? I was thinking the 4 140mm Noctua NF-A14 ULNs in the top of my cabinet, which is open to the room, would be enough. The electrical equipment is actually below the TV in my case, but there is no back to the Cabinet where the equipment is located, so the air should flow through there well. It could be a couple of weeks before the TV gets here, so I have time to do it now.
yeah, I actually read through that. My problem is I don't have the 4 inches all the way around and I'm looking to remedy that with some fans in the cabinet. I'll put a thermal switch is so that it doesn't even come on unless it actually gets hot. I think that should do it without too much hassle or expenditure!
