I am having the same problem - very frustrating. To test, I created a powerpoint file with thin red, green, and blue lines against a black background (lines thiner than 1px always render at exectly 1px wide while editting - convenient . I found that none of the colors were focussed close to the full resolution of the set. Line widths vary from about 1/16 to 1/8 of an inch around the screen, but are never better than that. At 1920x1280 on a 55" model, pixel pitch should be roughtly 1/40 of an inch, so these lines are about 3-5x thicker than they are supposed to be! So, not surprising that text looks blurry.

Even more bizarre - individual red and blue horizontal lines actually show up split as two lines (or, think of it as a wide line with a thin black line in the middle). This sucks.

Has anyone else done a similar check? Sounds like some people in this thread are doing OK with convergence / resolution tests, but it seems like this is an optical problem, and must be limiting resolution for all sources. Has there been any progress on tweaking computer displays that I missed? The last post I found on this topic is about a month old.

My hack for now is to change the windows font size to 125%. Still looks pretty awful, but easier to read without getting a headache.

SONY issued me a LPF fix!

I had called them shortly after the CNET article made light of the problem and was told that SONY was working on a solution. I did not think they would do anything and since Googer made the settings in the service menu known, I did not think anything of the issue up until now.

The box is labelled "Test Pattern SW Update" and enclosed are an instructions sheet and USB dongle. It lists the current flash and file versions as being from May 2006 with the newer flash and file version being from August 2, 2006. I am assuming that TV's made after that latter date have the fix already.

Is this something you could upload for others to use?

Yes, I just tried your test. Created a PPT slide with black background and large black boxes with very thin edge lines (one each R, G, & B). Looks clear and crisp to me. Can't be more than a single pixal wide.

Also, various color text on black background (this web page), small text in the Windows menues, and small black text on white background are all crisp and ledgable from 7 to 8 ft and closer. (Actually, the black text on white background is a little tougher on the eyes since the white is so bright).

I note that you say you've changed your resolution from 1920x1080 to something less. I haven't. I know you are trying to avoid having the image clipped by the enclosure (due to the overscan), but, I'm guessing this introduces some scaling by the A2000 when you want it to map pixals 1 to 1. I've not worried about the overscan, just work with windows within the viewable area (or mostly watch video full screen and don't care about loosing a little around the edges).

I also wonder about your settings, if you are trying to drive some too high thus getting a fuzzier rendering. I have my settings for Video 7 at:
Picture = 60
Brightness = 60
Color = 44
Hue = 0
Sharpness = 50
Gama = Low
BC = Low
EC = Low

I have done the LPF fix and Gama settings Googer recommended as well as adjusted my white balance in the service menu.

I assume a DLP - using a single mirror per pixal rather than having to converge three microdevices - would be a crisper, but, I'm very happy with my SXRD's display of 1080 from my HTPC via DVI to HDMI.

Holy WOW! Thats nice! I am interested to know for sure if they fixed this issue in the September builds... Also If I get a new optical block (I have the green blob) will this mean I could have the LPF issue and not know it? Or is this something else within the TV that sets this?

Also who did you have to talk to, to get this?

I posted this in the owner's thread before I discovered this thread, which seems a more appropriate place.

My friend has has his 60" A2000 for about 2 weeks, and he is happy with it, except that he says the "colors are a bit off". He is non-technical, but I am a tekkie, and I am going to visit him next week.

I am looking for your advice as to how I may be able to help him tweak his set without destroying it. What tools are out there? I have read here about calibration DVDs (Avia?), a set of settings to start with (thread # ??) and some other stuff.

What do you people recommend that I do or use (if anything) to help him acheive a better picture? His set is being driven by a Comcast box, and he has a non-upconverting DVD also connected. Thanks,

Sam K.

I wonder if it changes more then the 1 number from 5 to 6 in the SM, or does it make more changes..

Need some help here guys. I had a 50A2000--very impressed with it so I went for the 55. Plenty big without overpowering for my room.
Here are my issues...
HD picture doesnt seem as clear. It is an August build so I assume the LPF fix is on...
TV seems to make a hollow slight popping sound when you turn it on (kind of like gently tapping your fingernail on the bottom of a dixie cup. )
I tired to get into the service menu but when I pressed the sequence of buttons it just changed the channel on me. I hit the "power" button...not the power off button all the way on the top right.
Am I doing something wrong here ?
post #1060 of 3250
Chad Billheheimer http://www.hdtvbychadb.com/ was just at my house on October 20th. My set was looking pretty good after using the tweaks from this forum. That was acheived thanks to Sourcery, Dave Hanckock, Googer, and in the earlier days of this forum, UMR as well. However, since I'm one of the squeamish types that didn't want to risk messing up my set, I had Chad calibrate my set. Aside from the user menu tweaks I perfomed, Chad was able to get the convergence more in line, improve gamma, brighten the IRIS, align the picture, eliminate green push. SD channels are imrpoved and HD now has the POP and 3D resolution I bought the set for.

Thanks to everyone who's posted quality tweaks on this forum. Keep up the good work.

It should make one little click / pop noise but not multiple... Maybe like 2 quick clicks.. but not much more than that.

Not sure.
The USB dongle is 64mb capacity and has the following files:

sony_dtv_upgrade.d06
sony_dtv_data.s06
sony_chassis_download.sc06
sony_dtv_data.u06

You never know if there is some hidden data though. In any case, your best bet would be to call SONY customer support as this fix is free.

Here is the instruction sheet:
page 1
Page 2
page 3

One other benefit to having this is, if you've made service menu changes and forgot the original settings, this fix will restore things to default settings. On the flip side, if you have had your set calibrated , this will probably erase all service menu tweeks.

Thank you for sharing.

I read through the Sony instructions you linked and I saw in the first paragraph "The TV was optimized for picture performance and not to resolve test patterns". So is Sony implying that when changing the LPF from 5 to 6 that it actually negatively effects some other part of the picture? For those people that manually changed their LPFs did they notice any negative effects after the change? Or do people think that Sony is using that statement merely to cover themselves.

I did the Googer fix earlier and found that it improved detail with no adverse consequences. Others felt there was no change in detail but no downside regardless. So far with the SONY fix, I don't appreciate any negatives either. It is more for piece of mind in any case.
post #1065 of 3250
Hey 406 how long did it take for chad to do your set ? Was it a full ISF calibration ?
Lastly on a scale of 1-10 how much better would you say the improvement was, ie "The best TV I've seen in my life" = a 10, 1= I should have bought a six pack of beer watched the game and just been happy with my own tweaks .
Thanks

Do we actually know that the service fix changes the LPF setting? Perhaps it makes other changes, too? I have an August build that I'm very happy with. I don't have a way to test if it's resolving the a full 1080P test pattern, but HD programming is very sharp so I'd be surprised if it wasn't. I'd be curious to know exactly what is being changed before I mess around with my TV that doesn't have any of the problems some people have noticed. I just did an AVIA 50IRE grey field test pattern and grey is grey with no pin or green in it whatsoever.

I think the best tweaks for this set will be when we can get a reasonably priced Gennum, ABT or Silicon Optix based pixel by pixel based 1080i to 1080P motion-adaptive HD video processor. Has anyone tried one of these with the A2000? I'm very interested in the results with regard to noise reduction and apparent detail during scenes of fast action video (e.g. HD sports) and horizontal panning.
post #1067 of 3250
My 55" is coming tomorrow (WOO-HOO ) and I can tell you I have NO intentions of going into the SM (this is my first HDTV ). I'll check the build date and give Sony a call, if it's before August, for the fix. Plus, call me naive, but I tend to think that Cnet was truthfull in that they couldn't tell the difference after the fix - even so, I want my tv to perform as it should.

As far as calibration, I've seen Chad B's name pop up quite a bit in the A2000 threads and it's all been positive. Do calibrators have "tv specialties"? It appears that an ISF Calibrator works on all types of tvs but do people match-up calib's to certain tvs? ie: if I have a Pio Plasma I should get 'x' calibrator, a Sammy DLP get 'y', a Sony SXRD get 'z'? I'm seriously considering having a calibration done in the new year so I'll be researching this more -- I need some time to play with my first HDTV and get a little familiar with everything.

Hmmm--must have been a new tv thing because the noise stopped. Plus it also seems that after 6 hours of being on the picture quality has improved so no problems there eiither
post #1069 of 3250
You know I thought the 55" would be perfect for my room...(seating ranges from 7-10 feet)---but I must admit I am a little overwhlemed at the size....even on HD.
Has anyone else felt this ? I find it a bit of a challenge just to take the whole picture in. I am considering returning it for the 50"--which I had before but thought the 55 may be better. So far it isnt....I am going to give my eyes time to adjust if they will. Right now I feel its just a huge WALL of VIDEO instead of a family rom television.

Chad arrived around 10:15 and was finished by roughly 2:30. He did the full calibration which included two inputs, as that's all I have in use right now. Once he got going, he was non stop, precise and informative. He evn worked through the lunch I picked up for him. I don't think you can ever really get to 100% but I would have to say I'd give a solid 9, or even 9.5 . Before he got there, it was probably about a 7.

I might add Chad knows the SXRD technology pretty well as he has the 60 inch XBR1.
post #1071 of 3250
To my knowledge, calibrators are not necessarily trained for just one brand, or type of techonology. However, one should ask the calibrator what experience they have on your type of TV. Chad happens to think highly of Sony's SXRD's, he has the XBR1 himself. Good luck, I think you'll happy once you get it done.

Did you ask or did Chad happen to mention if the green blob in the SXRDs can be reduced or eliminated through calibration?

I've just added your report to the calibration list which is linked at the bottom of my post. If you have further comments about your calibration just edit your original post.

Thanks for the report.

I don't believe calibration can correct the notorious green blob. I've haven't had that problem with my set, but Chad did on his XBR1. He said it's pretty much corrected itself the longer he's owned the set. You might want to contact him through his website and ask him directly, just to be sure I'm not misrepresenting him.

Okay, thanks! Hope it's useful for others considering purchasing the set, or calibrating the one they have.

Easy question to start out the day.

I just purchased the kds60a2000 on Sunday and have been playing with the TV. I assume I can hook up antenna to TV to receive local HD channels, is this correct? I currently have dishnetwork, however I don't have local HD channels so I was hoping I could grab signal OTA using the TV

Thanks

Yes, that's what the Antenna input is for.

Yes. Most (not quite all) of the HD stations are currently UHF so you will probably need a UHF antenna. Depending on where you are located, these stations may be harder to pick up reliably than you may think. So an outdoor antenna may well be in your future.

I have an indoor Silver Sensor antenna by Phillips and it works really well for me. It is UHF only, so if there are any VHF channels you do want to pick up you are pretty much screwed.

Take a look here for some help choosing an antenna. You could also look at the forum over here to find your hometown and get some help.

If you have an old pair of rabbit ears lying around try them first before shelling out for an "HDTV" antenna...you may be pleasantly surprised. Working great for me although the towers are only about eight miles from me.
