That looks like banding to me this TVs are notorious for that mine has them all over but once you play an image it disappears.

This has started on mine as well. It is the 46D64U but is now out of warranty. Typical I guess. I'm really disappointed now. Mine does not go away though.

My only thought is after some time, the TV got warmer and the "frame" expanded and filled the gap, maybe?

Any suggestions will be really appreciated!

My 52" does that too- less than yours though, and it ALWAYS goes away completely after a few minutes. It does look like a "warm-up" thing.

Hello all,
After reading this board, I figured I would post this here and see if you guys could help me find a solution. I already posted my own thread but it doesn't seem to be getting many hits. About a year ago I purchased a 52D64U through Sharp Direct. I am a big movies and sports watcher, but my sharp really struggles in these areas. When watching HD channels through my scientific atlanta box from Comcast, I see a lot of "noise", looks like color static, in the background of the picture where there is a lot of color contrasts or light to dark contrast. I then went and purchased a Sony blu ray player hoping that would help, and hooked it up to my tv via an HDMI cable I ordered from monoprice.com. The picture noise was just as bad if not worse when watching blu rays on the player. I can only explain it as a static in the colors of the picture, it seems to be worse in darker colors such as blue. I contacted Sharp about the problem and they sent a tech to my house who saw the same thing I was seeing, so sharp had him replace the main board on the TV. It did not help at all. This was about 4 months ago However Sharp said that if there was a problem with the TV that would have fixed it and that it must be a problem with my blu ray player, even though I am seeing it on all sources.. After several phone calls and me arguing with them about it, I gave up. Luckily I opened the case within my 1 year warranty, although I believe I am right at my 1 year warranty now or just barely past it. However, I believe since the case was opened during my 1 year warranty period I should be ok... I'm hoping I can somehow convince them to give me a new TV if I can't figure out a way to make the picture look better. Do you guys have any suggestions or any ideas as to what the problem could be? I've tried CNET's calibration settings and they didn't look very good. Does anyone have any idea what could be wrong? Any suggestions on what I can do to fix it? Settings? Thanks in advance guys.

First try to lower the sharpness setting, otherwise some movies have graininess added for effect on blu-ray as well. But I do notice the noise as well in high contrast dark scenes, but I'm not sure if it's the TV or the cameras used in filming the scenes. I can only assume it's difficult for a camera to pick up light during a dark scene, and if they jack up the gain to compensate, causing the graininess, not sure.

Also, did you register your TV with Sharp and become an Aquos Advantage member? If you did you get an extra 3 months of warranty.

There are lots of things that could be wrong here. What AV Mode are you using to view your movies (should be using 'Movie')? Have you customized the calibration at all, it does seem like the sharpness is set too high (it should be around 0 to +2). Below is a GREAT start point for calibrating this set, done by a fellow AVS member. I have adjusted mine slightly (shown in () ), but this should get you started. Make sure you are using the 'Movie' AV Mode and give it a shot.

Mode: Movie
Backlight: STD (Now, I have OPC turned on unlike the person that came up with these and the Range is set at 0 to +6... 0 looks great in a completely dark room while the +6 setting helps brighten the set when the lights are on)
Contrast: +29 (+35)
Brightness: -2 (I have played with this setting anywhere from -2 to 0, and the blacks look better at -2)
Color: 0
Tint: 0 (Adjust at own taste if picture is too green)
Sharpness: 0 (Could be set anywhere from 0 to +2 depending on personal preference)

(The rest are found in 'Advanced Settings', These were calibrated by a member that goes by SamS, and he knows what he is talking about, just set these here and done mess with them, lol)

CMS Hue
R +6
Y +3
G -23
C -2
B +12
M -4

CMS Sat
R +10
Y +30
G -5
C -30
B 0
M +1

Color Temp: Low

We have the same set by the way, and am completely blown away by its performance. We are using a Magnavox Blu-ray Player running at 1080p via hdmi and the black levels (areas where you are seeing the most 'noise') are just outstanding. So, there has got to be a problem with your set, wither it be hardware or calibration. Give these benchmark settings a try and let us know how it turns out.
post #5557 of 5830
Ok thanks for the help. I'll try this when I get home and let you know how it goes.

Mine looks best with those settings (I have the same exact TV as you, the 52D64U).

On my TV I can put the contrast all the way up to +31 without it blowing out the whites. Not really a solution to your problem, I know.

Another update about my debacle. So the LC32E67U they said was available isn't now. I guess it's a stock issue. So when I called today, they advised me the DO have something for exchange (finally), but that it would be a refurb LC 32D47U. I asked if I could call back before deciding so I could look it up. Turns out, this set sells for $450-$500, depending on where you buy it. Am I wrong in being a little upset about this, that this seems like a rip-off? What I mean is, 7 months ago, I paid $750 for my LC32D64U. Now, they want to offer as an exchange, a set that costs $250 less brand new, much less at a refurb price. I know price isn't everything in terms of performance, but this isn't about performance....this is about getting what I paid for. And I paid $750, so why would I accept a tv that costs $500? Am I thinking about this in the wrong way? Is the price 7 months ago not apples-to-apples with prices now? Any advice. I'm really frustrated at this point.

Hey if you could take the time to read this you'd be helping me make a fairly large decision. Thanks

That sure is not an equal TV. First it is an older model and second it is an inferior TV, 720P vs. 1080P. I would not accept this exchange and would demand a better deal.

I've had my 46" since the infamous CC Black Friday sale in 2007. Well I got my FIRST set then, then exchanged it in January for one of the sets that would do the 24Hz. It hasn't given me any problem until this past week. About 50% of the time I start it up I have a solid single vertical line of pixels that are stuck at red about 2 inches from the right of the screen. After about 5 minutes it unsticks and is normal for the rest of viewing.

Anybody else have this problem? Is it a sign of further problems?

I am pretty sure I am SOL when it comes to any warranty or anything with Sharp as I didn't extend after the years + 3 months (for registering with Aquos Advantage).

I'd like to program my universal remote (MX-500) to be able jump directly to an input (TV, DVD, DVR) on my LC-46d64U rather than having to cycle around the inputs via the Input button. Does anyone know if this is possible and, if so, how I might obtain the correct codes?

I did a search on this thread for "input remote codes" and found this site listed: http://www.remotecentral.com/cgi-bin...hread.cgi?4089 . Looks like each input does have a code and Harmony may automatically be programmed for them. I have not done remote programming for the TV so cannot answer any questions. You might also think of a better search within this thread to find more info. /Dan

So after reading all the negitive posts here, I'm a bit worried about purchasing a used set. I found a local guy selling a LC46D64U and a Samsung BDP1500 Blue-ray player for $700. He said it was purchased in November or 08 so I do have a bit of warranty left in case of a problem. Is there anything I can look for or quick tests I can run besides just hooking it up and seeing picture quality.

Why is the guy getting rid of it? Not happy with it? Problems? Make sure the back light is even across the whole screen. Look at a completely white screen and check for any banding, these sets are notorious for that...

See here for a good example of banding...

Guy is moving to a smaller house after the kids left and they bought a 32in Sharp LCD instead of the 46". The guy seems very up front and we had a good chat on the phone for about 30 minutes. I mentioned the banding problems and he said he didn't notice any but I was more than welcome to fire it up at my house when he delivers it and test it out.

I remember see a link on this threads about a DVD test that you download and burn, something like TVflicker or something?

I woke this morning to a technical issue I can't seem to resolve. Last night everything was fine -- I was watching TV OK. I got up this morning and I have no audio on my LC-42D64U. I have changed it back to audio on the TV just to eliminate the HT receiver but that hasn't helped. NO audio...

Here's the kicker: I'm getting audio on the digital channels -- i.e. the 7 or so Hi-Def channels that come over the cable. I don't get any audio on the analog channels, however, and they appear as "mono" instead of "stereo" in the info pop up window.

I don't have a cable box -- just basic time warner cable connected directly to the T.V. Audio is still working on a fairly old tube TV in the bedroom so it is not a technical issue with Time Warner. It seems to be only the mono signal from the analog channels that have gone sound. Any ideas?

I also have Time Warner and have experienced the same thing from time to time and have been able to get the audio back by either just switching back and forth between the station I do not get the audio on and one that I do. And once in a while I have to cycle the power on the set and that resolves it. But you say you get the audio on the hi-def (digital) stations but not analog stations; was that before or after you eliminated your HT receiver? Check the volume to make sure it is not at zero (which is where I keep mine when using my receiver instead of the built-in speakers.

Good luck.

My 14 month old LC-52D64U just stopped working. The green power light blinks but nothing else works. Fortunately I have the 15 month warranty through Aquos Advantage and I have a service call scheduled for next Wednesday. Does anyone have any idea what might be wrong and how I should handle the service call? The TV's been problem free until now!
post #5573 of 5830
I'm sending channel commands to two LC-52D64U's via RS232.

I'm able to use the 'DCCH3***' (*'s are spaces) to tune to analog channel 3, and then 'DCCH?***' to ask the TV what analog channel it's on. That works just fine, I get back '3'.

However, there are digital cable channels in the 1500-1550 range and to tune those in I use the command, 'DC101504' to go to channel 1504, for example. But I am unable to use 'DC10?***' or 'DC10????' or any variant of this to ask the TV what digital cable channel is tuned in.

Trying to use 'DCCH?***' always says, '2' which is wrong... seems it can only work to report if an analog channel is tuned in.

Does anyone have ideas or suggestions on how I might get these to report the current digital cable channel?

I have read the manual and called their 'operational assistance' hotline; local 'authorized service centers' were a joke.

Thanks!

For you and the guy with audio problems. A full reset involves unplugging the set for a minute or so and plugging back in. Solves some problems. Glad you have the warantee since I think flashing green is error. Try the unplugging.

My almost 2 years old LC-46D64U starting to have a big white blotch like cloud spreading from the center of the screen... Does anyone know will Sharp fix this? Is this fixable at all?

Just like some post before, the blotch appears to be more noticeable when in dark background.

What is your backlight set at? Was tv every layed flat on the floor with the screen facing down? Or did anything hit the screen lately?
post #5577 of 5830
it used to be a small blotch before, but recently it gets larger.

Last night I put my TV face down on the sofa so that I can install the wall mount on the back of it. But the blotch was already big enough during that time anyway.

Will Sharp able to fix this? Will they charge me for that? It's only 20 months of usage, and the TV already turns bad...

That seems to happen sometimes when the tv is face down like that. YOU can try and fix it before you call them. Get a microfiber cloth and try to see if you can massage it out. If is part of the screen depressed, you may be able to fix it, if not looks like a repair from sharp is in your future...

wow, xboxFreak, it WORKS!!!!!

I just used a cloth to massage it a little bit, and the shade is totally gone now!!!!!!!

many thanks!!!!!!!

Im glad it worked out for you. I had read of someone laying one face down on a pillow to removed the stand (to wall mount) and the same thing happened, they managed to "massage" out the discolorations...
