Official 2012 Sharp LC-XXLE640U/XXC6400U - Page 9

post #241 of 1345
Myoda, I'm happy to upgrade my amp, but I'm not sure I see the whole picture. If I feed the amp the HDMI with DTS audio, and then the amp feeds the TV the video via HDMI, it would seem that the primary problem in TV video lag still exists. You mention that today's amps can accomodate the audio sync problem, can they do it on the fly? For example, the audio sync issue varies based on which TV setting I'm using (i.e. - how much processing the TV is doing, game, movie mode, etc...), so can the amplifiers basically sense the problem and auto adjust? Do you have any recommendations for good amps?

Thanks in advance.

Okay, after scouring the manual, I finally found these two bullet points on page 15 that would explain why I can't select digital output when the only video source is from HDMI;

"• Depending on the connected equipment, audio will not output from the DIGITAL AUDIO OUTPUT terminal in HDMI
connection. In this case, set the audio formats of the connected equipment to PCM, 32/44.1/48 kHz.
• Optical digital audio will be output in 2-ch stereo when it is from the external equipment connected to the TV using an HDMI cable."

I guess the only options I have at this point are to upgrade the amplifier (for ARC HDMI compatibility and audio sync issue resolution) or return the television.

Sharp is going to be replacing my LC70LE733U due to a yellow line running straight down the entire screen. I was highly satisfied with this TV until then.

My question is, since they dont make that model anymore and will be replacing it with a newer model, Im kinda iffy on which one I should get. None of the 70 inches are full array now so Im actually going to go look at one of them and see what it's like.

Second, I read on the CNET reviews of the 640U that it doesnt handle blu ray movies well with 1080p/24 encoding. Is this true for anyone? My main reasons for this TV would be for gaming and blu ray viewing (though more on the anime side of blu rays) but I dont want my TV to be skipping all over the place when I watch a movie. I mean, I used to have an LG and just kept it on the 60 hz mode and never saw a problem with my movies but Im not sure if this is different or not.

Any help is appreciated.

Watching football tonite on my 60" sharp 640 thru Directv, I have noticed two things:

One- herkey/jerkey movement in motion plays.

Two- HD picture quality for sports is NOT as good from Espn's 720p. Don't care what anyone says, I can see the difference.
post #245 of 1345
I've owned the LC-70C6400U for two months now. Not a terrible TV, but I can't figure out how to get the refresh to improve for live sports (saw this mentioned in another post in this thread). Golf is real tough to watch with the trailing of the ball behind the ball. Same thing can happen in a baseball game.

Any tweaks I can make to eliminate this? My 65" Panny Plasma doesn't do this (obviously) nor does my other LCD I own.
post #246 of 1345
did you turn off 120hz,video noise reduction and all other motion enhancements?
post #247 of 1345
Yes, tried all of that.
post #248 of 1345
did you try game mode?

Nope, I'll give that a shot and report back.

And check. I'm really disappointed in the way football comes acoss on my 60le640u... I see a lot of motion judder... really detracts from the experience. The picture quality on ESPN football broadcasts on my 60le640u is a distant second to that of my 2009 Toshiba Regza LCD - although it's not just football that it lags behind my Toshiba, IMO - it just shows up in football the most.

The only way to get rid of the "ghost" balls in golf and baseball is to turn off the motion enhancement entirely. I know, it's ironic that one would have to turn the motion enhancement off in the area where you would think it would be of the most value, but that's what we've got here!?
post #252 of 1345
I should add to the above that when I'm watching golf or baseball on my set, I'm in "User" viewing mode. I don't see the ball ghosting with motion enhancement and cinema mode "OFF" in my custon User settings, but I do get what I think is best described as motion "judder". It's like the players in motion are distorted as if they are dematerializing and reforming, not the "motion blur" one is accustomed to seeing with objects in motion.

I know what you mean. Similarly, my wife and I were watching the Cowboys/Giants game last night and I had it Game mode - thinking that is the most pure way to watch it. But, most noticeably on shots where players were switching sides (running off and running on the field) the picture would become blocky and static like, or as you said, like they are beaming up to the Enterprise. So my wife says, did you change something why don't I feel like they are in my living room anymore? So it went back to dynamic mode (I think) and motion ON. I have the 70 inch 6400.

Edit: I just realized you said you got OTA from one Antenna but not the other, which indicates the RF input is working. Maybe your RG-59/6 cables have either a bad connecter or center conductor is not long enough to make a connection with the RF connector on the TV.

Schlenker, thank you for your response. It turned out to be the center conductor not long enough. My previous TV must not have needed it very long, but this TV sure does. All working now, love it.

I haven't tried watching football with motion enhancement on. You're not seeing any "ghost" balls when the football is in flight with motion enhancement on? I'll find out for myself Saturday, but I'm having to work nights this week, so I'm not seeing any football right now.

This option is available when you are on the TV input. I guess it doesn't apply to HDMI based on what it says in the manual on page 15, but I thought HDMI carried 5.1 audio so I don't really understand why.

I purchase the LC60c6400U 2 weeks ago and I'm returning the TV today. The blur in sports is driving me crazy and the blacks are awful too. I try everything, the fake 120, 240 turn those off, play with the colors and still not happy with the picture quality.
post #258 of 1345
What I have learned since owning this model and purchasing the Disney WOW Disc.

Active contrast=local dimming and should be activated AFTER calibrating brightness, contrast and color. If you keep it off, the picture is too muddy. (But you do notice when the dimming occurs between scenes.)

24 fps is too soft, so I use film mode/advanced at lowest setting to sharpen motion.

Hi,

I have been looking at the LC60C6400U at Costco because I prefer a non 3D set and don't really need a web browser.
What I was wondering is this a current model or will new models be coming out anytime soon?

Thanks
Frank

I'm thinking of buying this TV and noticed that it has an ARC channel, but my receiver (Pioneer 820-k) only has a HDMI OUT. Currently I have my devices in the AVR's HDMI IN ports, going to my older LCD's HDMI 1 IN, which works, can I simply connect AVR to this TV's ARC via the HDMI OUT port on the AVR?

Keeping in mind that I do not care about receiving audio FROM the TV but want to have all components connected to the AVR and have It push the video and audio to the tv in HD if that makes sense...question is can I use the HDMI 1 channel on this TV for that purpose as I did with my older Toshiba LCD

Looks like your receiver just missed having ARC functionality. Yes you can use any HDMI input on the television from the receiver . If you want audio out from the tv in the future, you would have to connect the optical out of the tv to the one of the two optical inputs on your Pioneer.
If you want to see the on screen display from your Pioneer, you have to connect it to either video 1 or video 2 on the 640 with a single RCA composite video cable..

I think I get it...sounds like I can continue to use my existing configuration BUT if I want to use anything that requires the TV's sound like smart tv options..I would need an Optical cable...is that correct?
post #264 of 1345
I scanned the thread and couldn't find anything referencing this specific issue.....
Have a 52LE640U mounted in a classroom. All signal is going in to the PC input. Motion Enhancement appears to be on by default and looks terrible! Pans are not even watchable.

The manual says that "When AV MODE is set to "GAME" or "PC", or PC format is being input, "Motion Enhancement" is not available." Is there anyway to disable it? It's clearly turned on even though the manual says it's not available.

Thanks!
Todd

That is correct.

FYI - Costco just had its largest price drop yet on the 70in, to sub $2k.

I'm still struggling whether to pick one up or not. There have been enough problems reported on this forum to make me conclude that you can get a Samsung for about that price that will likely have less issue and better quality picture, but the trade off will be a 60 in instead of a 70 in. I'm coming from a 55 in Vizio 552 which I've never been thrilled with so either would be a step up in size. I'd love to go with the Sharp, particularly with this price drop, but would hate to have buyer's remorse by going size over quality.

60LE640/6400 is a pretty good TV. Some people are not happy with 70" version since it is edge lit. Last year model 70LE632 had local dimming. You need to compare apples to apples. 60 vs 60, not 60 vs 70

If you buy it from Costco, you have 90 days to evaluate the TV. If it does not work out for you after 3 months, return it. That is a pretty good price for the 6400U...Don't know about Samsung not having issues. When I worked as a rep for various CE vendors in Best Buy, the number 1 ob (open box) televisions that I observed were Samsungs.

Hi,

I just got a LC-60LE640U and I have some questions about it. So far I'm pretty happy the picture quality but I have some audio delay. My PS3 is connected to the tv via HDMI and to my Harmon Kardon AVR-245 receiver via optical. The audio on the receiver is way ahead the picture on tv. My receiver has an A/V sync delay but the max possible value is 80ms and it's still slightly ahead. I've already disabled Film mode and motion enhancement. I had an 2008 Samsung 40" LCD before and never had trouble with lip sync. Unfortunatly my receiver does not have an auto sync option over HDMI, it only has HDMI switching ability.

Is it normal to have a video processing delay over 80ms on that particular tv ? If I use the tv speaker, the audio is perfectly sync. Moreover, I discovered that the a/v sync delay setting of my receiver is global to all sources despite that the instruction manual states that it is individual to each input. So, if the delay is not the same for my Xbox, PS3, Wii and cable box, I will have a major headache !

Anybody else had trouble with audio delay with this model ? Should I exchange it for another model ?

thanks for your help!
