My website also always contains the latest testing results.

I, for one, applaud closing the thread. After spending a hour or so, reading through all the threads, a "thorough" summary of the status of this issue is welcome. Goo job JHanson! I for one, appreciate your efforts...

RickPas, which model do you have? Commercial or consumer?
post #33 of 469
Can't you just adjust the horizontal position using the set's service menu?

I posted this on another thread. Here it is again.

My Panny had the same problem after only 3 weeks. I purchased on the internet so, I had to have it serviced locally here in Houston. They picked it up and it sat in the shop because they were waiting for a DG (PC) board part. At the time the part was backordered with no arrive time scheduled.

I was getting upset about this problems so, one day when I was home sick I called Panny a number of times and finally got a supervisor.. and talked to him about getting a replacement TV. He talked about sending the broken "Board" to be fixed. anyway he called parts and they sent out a new board on that Monday. Basically, it took about a month to get my TV back because of the part and when the repair shop could deliver it.

FYI: the repair shop said that they have had a number of these type of TVs that had problems with that board.

I posted about this problem on this board a few weeks ago...People didn't seem very interested in it at the time. I guess they will now that their TV sare breaking.

My TV was made in April...may be they had problems with the early production TVs???

Yes, we can hope they fix the problem, but I wonder if they did much testing with the S-Video input. Remember these are commercial/industrial plasmas which are nominally intended for commercial display use. So the testing may have focused on the VGA and component inputs, and not so much on S-Video which is more likely to be used in the home. Although I may be wrong on S-Video use as a store display.

Since this problem shows up only with the 7UY commercial modes, has anyone tested for this in the Onyx models? The Onyx uses 7UY glass and presumably some of the electronics. But I don't recall having read a single hands-on review from an Onyx buyer here, so we don't have much info on those.

I hear what you're saying but on the other hand a manufacturer has an obligation to test all components of a system. One of the statements that Panasonic has made is the problem does not show up with their broadcast quality test equipment and they have hinted that the problem could be the consumer level DVD players that people are using. But their argument breaks down when these same DVD players do not exhibit the same behavior on different displays. If they insist on blaming the consumer DVDs then they can add their own players to the list. I have tested a F87 Panny DVD player and recently got ahold of a S97S player which is one of their better DVD players that features the Faroudja chip, and both have given the same results when connected to the s-video input.

Also if you look at the manual it shows that you can use sources such as DVD players, VCRs, and camcorders. There is no disclaimer that consumer level devices can not be used with this display. You can also bet that Panasonic has been cleaning up by selling their commercial displays to consumers for home usage and they are well aware that their panels are used for this purpose. For them to benefit from the consumer market and then turn around and try to blame a problem on consumer devices is pretty lame in my book. You can't have it both ways. If you are going to sell to a market then you are obligated to service that market when there is a problem. And I believe the facts are showing that the problem is not the consumer sources that we are using since I have not seen any reports of this problem on other non-Panasonic displays.

In the quote from Visual Apex there is a statement about most people using DVI or component inputs because of their superiority to s-video. I don't doubt that this is true. Even though those inputs are superior to s-video that does not excuse the poor performance of the s-video blade on this plasma. This s-video blade is not functioning as a s-video input should function so you can't try to say that it's just because the other inputs are better. I do not expect the s-video to look as good as component but I do expect it to perform to the level s-video is supposed to perform to. If s-video is not relevant then why did Panasonic include it on this plasma? I think the answer is that there is still a lot of s-video equipment being used by people.

So the fact that this is a commercial display and the DVI and component inputs give you a better quality picture is not an excuse for a substandard s-video input. I do have a use for this input and I need it to function normally.

I understand that people from Panasonic are reading this thread and I hope that is true and I hope they will listen to this appeal.

Dear Panasonic,

The s-video input on my 42PWD7UY is not functioning as it should. I have documented the problem with pictures and descriptions many times on this site. I have tried to contribute as much as I can to help resolve this problem and I understand that you have people looking into this as well. I believe that you have been aware of this issue for at least a month but I understand that you are having trouble reproducing the problem. I'd like to help you with that because it is REAL EASY to reproduce if you have a display that behaves the same way mine is.

1. Simply connect one of your F87 or S97S DVD players' s-video output to the s-video input of a 7UY plasma.

2. Set the picture settings for this blade to factory default.

3. Load the pluge pattern from a Digital Video Essentials disk, chapter 12 first pattern, and take a look.

If your display does what mine is doing you will see a glowing band across the top of the screen and you will also see missing parts of the pattern at the center of the screen. If you increase the brightness of the picture to make all of the pattern visible then the glowing will become more apparant. You will also see some noise toward the middle of the screen.

If you do this and can not reproduce the problem then that means there is something wrong with my set and I need either a new blade or a new display.

If you do this and can reproduce the problem then I think that shows that you have a problem with this series of plasmas and it needs your attention.

If you reproduce this problem and are unable or unwilling to fix it then please refund my money and take your set back.

Thank you,

Rick Williamson

I am curious, what kind of tests did you perform? Did you happen to use the APL pluge pattern from the DVE disk?

Thanks.

Hello,

I've had the 42 ED 7UY for about four days now. I ordered it from VA after reading the posts on the blooming because I loved the picture I've been seeing of the 6th gen consumer in stores, and I never use S-Video. I was going to pick up a copy of DVE, but the picture looks so incredible by fiddling with it for a few days I'm not sure if I should bother.

I'm guessing that if I get a copy, and hook it up through S-Video, I will probably see the blooming - but I'm not sure if I should bother. The idea of bug hunting when I'm happy with the purchase so far seems a bit odd.

I have been following this thread as I been researching panny plasma sets for a while now. I decided on the panny TH-42PHD7UY for all the good things on PQ, black "blacks" and swappable boards. Now I am trying to decide on who of the forum sponsors to send my money to to get mine. :)

I appreciate what rickwil61 and jhanson have been doing...I am sure Panasonic will fix this issue once they have a answer but like many companies this kind of issue doesn't get to those who can do something to fix the problem until someone like rickwil61 and jhanson takes the effort to document it.

Keep up the pressure rickwil61 and jhanson...your doing a great job.
I have subscribed to this thread and look forward to Panasonic's answer and fix for the problem.
post #42 of 469
I have the HD version of the same one... 37px25up

Bad DG board, didn't get the TV back for a month. It's a known issue to the Panasonic service center, the part was backordered for 2 months when mine went down (just 4 days after I received it).
post #43 of 469
Can you describe your problem in a bit more detail?

I have the PWD6UY and a few weeks ago I noticed that while watching a DVD the image was shifted up. So I adjusted the vertical position to fix this - later in the movie the top 10 horizontal lines started showing "off screen" material. I had to sctretch the vertical size to account for this.

Seemed strange to me so I just assumed the DVD was the problem. Since then I recalibrated with DVE and all has been good...until I bought a few more movies and the same thing keeps happening.

As Ricpas has said, HD content is not an issue but some SD channels have done this to me as well.


What is the DG board?
How can I be sure this is the panel and not the DVD player or DVD movies?

Thanks!

Any resolution from the Panny or VA front yet? Just curious how you are doing.
post #45 of 469
VA told me yesterday that in their view:

1. It only occurs on the S-Video and composite inputs
2. The problem does not occur with all DVD players - just some models

Visual Apex has been unresponsive to my emails. I received a snail mail letter yesterday thinking it was something about the problem. Instead it was a generic letter stating how surprised I would be at their "hallmark customer service." I think they have been testing a few things but are mostly waiting for Panasonic's response. It would be nice if they were willing to work with me directly to test and troubleshoot the problem but for some reason they choose to be unresponsive. If Panasonic does find a problem and provides a solution, I have no doubt that Visual Apex will jump on the boat to implement a quick and smooth solution with their customers.

Panasonic appears to be looking at the issue slowly, but surely. I don't feel they are blowing things off. There still is no word that anyone at Panasonic has reproduced the problem, but part of that is that they have a hard time getting a panel to test and they are also waiting to get the DVE disc in so everyone can be looking at the same thing. The issue does seem to be getting attention in different parts of Panasonic (US and Japan). They also seem sincere in at least trying to reproduce the problem (which shouldn't be that hard even with their top of the line DVD players). Like any big company, things progress slowly. Panasonic US hands are somewhat tied until Panasonic Japan makes some sort of response to the problem.

I'll keep you guys updated when I hear anything else. Please continue to use your channels to report the problem to Pansaonic.

**** IMPORTANT THREAD ID CHANGE ****

The moderators were nice enough to make this main Panny 7UY Problem thread "sticky" so it stays at the top of the Flat Panel forum. In the process of doing this, two Panny thread IDs inadvertantly got switched.

To accesss THIS main Panny Problem thread, you now have to use this link:

Problems with the Panasonic 7UY Series

You will have to re-subscribe to the new thread ID if you want to keep getting emails when new posts are made in THIS thread (the one you're reading).

Thanks.

post #48 of 469
As usual, please take the following as UNOFFICIAL !!!!!

The "bird" has overheard that using the DVE DVD, John's pluge symptom has been duplicated both at HQ and in Osaka.

Various DVD players were used including the venerable RP-91. The better DVD units did produce a better picture but could be made to show the black streaking and uneven black background.

Typically, PICTURE settings could be anywhere from +10 --> +30 and the BRIGHTNESS seemed to show things their worst at (- 8)

The DVE DVD, sponsored by EKTRON, well known in Broadcast circles checked out quite favorably for technical quality and accuracy as viewed on waveform monitoring equipment.

No clue as to where the problems are developing but more study is on tap.
post #49 of 469
Speaking of DVD players I was able to get a hold of a Panasonic S97 on a temporary basis. I turned on the enhanced black settings and progressive scan, and set the picture mode to normal on the player. For the plasma this time I used the dynamic picture setting with everything at factory default. I used a Monster s-video cable to connect to the s-video blade.

Here's what it looks like. This first picture is an open shot of the screen that was generated using these settings.

post #50 of 469
This shot is of the same screen but this time the center rectangle is covered up. The camera can not capture the side bars unless the rectangle is covered. If you superimposed the first picture over the second then you would get a good idea of what this screen actually looks like.

post #51 of 469
Here's a shot of the S97. This is one of Panasonic's better DVD players and features the Faroudja chip. I don't doubt that the problem may show up worse on some players than others but that would be because the players in question will have varying picture quality. As for this problem I really doubt that the DVD player is causing it. Especially since I have tried a few different players with the same results and also verified that they don't exhibit this problem when connected to a Panny CRT TV.

***BUMP***
Amazing how a thread can get shuffled to the 4th page so fast..

Can one of you guys describe in more detail what you saw and how you "proved" it wasn't the DVD or player?. Since I have run accross this a few times I want to make sure I am experiencing the DG board fault before calling.

Bigshowdj, Rickpas, Barbwire21...anyone.

Moderators...shall we tack this problem onto the "7UY" sticky recently added?

Thanks guys
post #53 of 469
What to look for is pretty simple, my whole picture shifted to the left so I was left with a big black area to the right of the screen and missing alot of the picture .....It will only be on standard cable or vcr, dvd...anything coming in on 1080i will not be effected.....THis is what I'm experiencing, and this is exactly what others seemed to have experienced also....
Panasonic has acknowledged the problem, I've had the panasonic service tech come over on Monday and I showed him and explained what the problem seems to be, he said he will have to do some research into it, he has not seen this before himself...It's 2 days and I havn't heard back from him yet.....I told him, just call Panasonic and they will verify it is the DG board......
Let me know if you have any other questions...

TW - Thanks for the continued updates. We appreciate the unofficial report that there is testing going on and that the problem is reproducible (even with Panasonic DVD players).

It is also good to know that you were able to verify the quality and integrity of the DVE disc since that's something that most of us are unable to do at home.

Keep up the good unofficial work...

post #56 of 469
I am considering the same set up (42PHD7UY and S97).
Would you say that the problem is almost gone with component connection and some tuning? How much better with some adjustments?
Is the S97 better or worse than the other DVD players you have tried with the 7UY?
How much are you "forcing" the problem with the test patterns and are you really going to be bothered during regular viewing after some tuning?

thanks rickwil61 for your work.
post #57 of 469
do these problems occur on the consumer 25U/P model?
post #58 of 469
RickPas -

What level of overscan were you set at for this to occur?
I had mine at 5% according to test pattern on DVE.

During the set up with DVE the image shifted to the left an 1" or so.
I shifted horizontal to accomodate.

During movies the image shifts down. I moved the image and ended up bumping overscan to 10% and haven't seen the issue since.

Did you try this solution?

I'm just running it on the component inputs right now. I was thinking about getting a HDMI blade when they become available later; that is if Panny fixes my s-video problem and I don't end up returning or exchanging my plasma.

Right now I have two players, the S97 and a Yamaha DVD-C750, of which I will end up returning one. As far as the component performance goes I think I like the Yamaha video better. It seems to be a little sharper and cleaner image whereas the Panny seems a bit soft and I don't think it handles the noise as good as the Yamaha in some situations. I believe I've seen hints of macroblocking on some animated screens as well. The Panny has a bazillion picture adjustments and honestly I haven't really went through it to see how good of a picture I can get. That isn't to say that the S97 looks bad but it's just that the Yamaha looks a little sharper and cleaner to my eyes.

For audio I'm using the optical out going into a Bose Freestyle speaker system. It has a subwoofer and two small speakers. In this scenario I think the Panny's s audio sounds a little better than the Yamaha. I haven't tried the analog outs because I don't have a receiver, so I can't comment on that aspect of the audio performance.

If you want to look further into the S97 there is a huge thread about it in the DVD Players forum. You can't miss it because it's about 100 pages long.

I'd say that you're safe with the component inputs. There may be a slight hint of extra brightness at the top and bottom of the screen but I'm really talking about no more than the presence of a few random pixels. It's only noticable with your nose about 4 inches away from the screen and it's nothing that you would notice while watching a movie at normal viewing distances. Overall I'd say that DVDs played through the component inputs look superb.

As far as the s-video problem goes, I think the S97 behaves about the same way as the others I've tested. Keep in mind that my reason for connecting a DVD player to the s-video input is for the purpose of calibration. I don't watch DVDs through the s-video input, however I do have my satellite STB hooked up to this input.

This brightness/glowing issue is noticable sometimes on darker scenes. It can look like a light colored haze over the top part of the screen that corresponds to the glowing bands when you display the pluge pattern. On brighter scenes the s-video performance on this plasma is awesome and I think approaches DVD quality. That's what is so frustrating about this because if it weren't for this issue, I wouldn't have any complaints about this display.

So I'm really not forcing a problem. You can see from my pictures what the pluge pattern looks like at factory default settings and how there is missing detail in the center of the screen. When you turn up the brightness to see the missing detail then the glowing bands become really noticable.
