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.
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.
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.
