Official Sharp 52" LC-52SB57UN Owners Thread - Page 9

The owners manuals on Sharps have always addressed the flickering line artifact that can occur in Dot Mode - This is not a fault of the TV as a newbie would suspect and think they have a flawed panel. Dot is about as close as your going to get to perfect on a 1080P panel. When this occurs it's because your viewing an HD Channel that is either cheating by sending non-HD content through the broadcast or field broadcasts that they frame which leads to over or underscan which is why you'll see the broadcaster often framing the content.

In Dot Mode the panel is FIXED NATIVE 1080P and that's all it can do but if the broadcast sends anything less you'll end up with that razor line artifact. Most often this will occur with late night rerun returns on local HD channels as they send it out as 480i or if you view a remote report on news/sports and you'll notice that they frame the content to prevent this proving that they are aware of it and that they are the source.

The artifact won't be observed on an SD channel since Dot Mode doesn't work on SD channels - it's not available in the Menu on SD Channels which is why one person may not be seeing it - switch to an HD broadcast Channel and it'll be there. Despite this issue Dot Mode is easily the best viewing mode for HD and makes viewing a 57" at 8.5' easy and immersive and even a 65" is doable withh Dot Mode and it's NEVER replicated that flickering razor line on my Blu-Ray and HD DVD or any TRUE 1080P source - never!!!I've owned three Sharps and Dot Mode is the best but understand it's the broadcaster that is the source that is not truly full HD contained within their broadcast signal that triggers it and they cover it often by framing with advertising, i.e.; GMA, ESPN, CNN and late night local SD Content fed through HD Channels (this content rarely gets any framing though and thus you get the dang flickering line as a result - you either tolerate it or use smart stretch or change the channel.

i'll have to check when i get home

Off the wall question. Since this is a christmas gift and I have yet to open it, Can you get this television to display a PC signal in 1920X1080 resolution in dot by dot? The manual states the max PC resolution is 1600X1200, I am however using HDMI cables to attach the system. If my process is flawed how might I attain this resolution if it is not listed.

I intend to hook my PC up from DVI to HDMI as well. I took the manual resolution statement to refer only to use of the PC VGA connector.

I am not an expert, but I assume PC through HDMI is capable of the same resolutions as any other 1080P source, limited also by your PCs display resolution capabilities, of course.

I have a question myself, for anyone who can answer. I have the 46" version of this TV and I can't seem to find VESA mounting specifications. I want to get a wall mount for the TV, but don't necessarily want to use the SHARP "official" mounts. Does anyone know these specs, or if you have used a non-SHARP mount, which one worked? Thanks for any advice!

The TV accepts 1920x1080p via the HDMI interface from a computer just fine. I am running a HTPC with a Geforce 6600GT with a DVI to HDMI to the Sharp TV at that resolution 1920x1080p.

Hey, ZeroCool, do you know anything about mounting this TV to a wall? I am having trouble finding the VESA mount specs for the 46" version of this TV.

I read in another thread that all Sharp 16x9 panels use 200x200. Any idea if this is true?

I did some searching on Peerlessmounts.com, and while they have a lot of wall mounts available for the TV, I am still not clear what the VESA standard is for it. Fact is, the Peerless mounts are way out of my price range...I was hoping to have a look at monoprice.com for something.

Thanks for any info!

What did you decide to do in the end? Keep the Sharp or the Sony?

^ thanks for sharing, mr

i'll give those a try sometime

oh and i share an apartment with my younger brother and he LOVES Dynamic code (especially for sports HD) and i keep telling him to use my standard custom settings which is a bit darker but less 'blocky' (the more backlight, the more interfacts appear) but he doesn't care.

so my question is this: if the TV is on Dynamic mode most of the time, will this kill the TVs' life-span much faster?

^ you answered everything I was wondering about.

hey, thanks! mr.

i'm so happy this TV has a perfect rating on the wal-mart site

well deserved since we paid such an awesome price.

i'm still very content! god, do i LOVE how my blu-rays look. star trek and inglorious basterds picture quality BLEW me away.

i really, really like this TV.

awesome, i know this tv looks amazing on blu rays

Can you please post your final TV settings...

sure i'll try to remind myself to do it when i get home (doing overtime so i'm not home 'til 9-10pm (pacific time).

okay, here's my current favorite standard settings.















FINE MOTION ENHANCE and ACTIVE CONTRAST = OFF.

again, these might not work for everyone but THEY LOOK AWESOME FOR ME



EDIT: everything not pictured = default

Anyone else getting noticable ghosting issues in dark areas? Light areas seem fine but for example, if i go into a game like Counter Strike on PC and look at a guy moving with a ski mask there is a bit of a trail behind it. Same goes for DVD movies. It's noticible and could it be a deffective panel? :/ Tried taking pictures of it but it dosent show up well on the pictures.

have you tried switching picture modes? (standard, game, dynamic, etc) see it that helps. i don't play my xbox on this TV (i do on my Sammy plasma) so i can't say i've seen the same.

will give these a shot tonight....anyone else with suggestions are welcome to chime in....

It looks like I have develop 2 dead pixels on my set... Honestly, I am not sure what dead pixels looks like.. But up close, I notice 2 pinhole type spots in 2 different areas on the screen.

Please help me identify what these spots are. In addition, what type of warranty does Sharp has for dead pixels on a TV set.

Moved this set to a different room and wanted to check out the internal speakers since i never tried them. the room was small so believe it or not i sounded almost OK. but i noticed that there was a small POP about every 20 seconds(kind of annoying). anyone else experience this with the speakers in this set?

I just set mine up last night - yeah, I know I could have set it up when I bought it but have been busy - and cannot find this dot-by-dot option under View Mode. My firmware is S0905201 so can I and should I update?

Thanks in advance!

You only get dot by dot mode for 1080i/1080p/720p HD input signals. What are you inputing? The TV's display should show you when you press the info/display button.

My bad. I see it now that I have connected my PS3 and am watching a movie...

Thank you!

How many backlight hours is everybody up to? I am over 924 hours on my Walmart 11/7 Sharp 52" LCD special.

Backlight hours are in the service menu. Easy to access with a Harmony Remote.

Warning don't change anything in the Service Menu or you may void your warranty or leave your TV unwatchable.

Without a programmable remote you have to unplug the TV then use the button on side of TV:
Press and hold Vol- and Input at the same time, while plugging in the TV, get to "K"
Release all buttons
Press Vol- and Ch<, service menu should appear

After the service menu appears, you press arrow down (from the remote) and the hours are listed in "BacklightAcutime". If you use the side buttons, your can press ch - until page two shows with the option.

To exit the service menu, press the TV power button.

I am having a different issue. Now, I have to turn the volume all the way up just to listen to it. Maybe I set something incorrectly somewhere but I can't see where I did and it isn't anywhere near as loud as what it was out of the box...

I just tried to do the firmware update (i had the "S" version installed, and it came back that I had the most current firmware...

In any case, I love the picture with the Toshiba HD DVD player and the PS3! I have to say that the picture now is superior to what I had with the JVC-Dila I have, except that I have COMCAST and their picture quality sucks locally here in Sangamon County, IL.

PS Happy 201st Birthday Abe.

So are these your final settings? Let me know please

Check out your volume on the cable box. My tv is loud, so I dont know why anyone is having problems. I have done no firmware update or anything.

I just recently purchased this 52'' sharp. I purchased it for really cheap and am slightly concerned in product counterfeits because of the deal I got. I paid 750 for a brand new set and am wondering if anybody is familiar or would know anything about counterfeiting. I would imagine its pretty difficult to counterfeit this tv, or just electronics on this scale in general. I registered my unit and the serial number seems legit (manufacture august of last year); it has the latest software on it, and I checked the amount of lamp life on it which corresponded exactly to the usage I placed on it. Nothing seems to really imply a counterfeit except the price. Let me know your thoughts. (oh I purchased on craigslist from a guy)

Seems legit, we only paid 898 for it new so 750 used makes alot of sence to me
