On a plain moving background or certain panning shots the screen appears to have lines on it - or rather the screen appears dirty looking. When the screen stops though the effect disappears.

I am beginning to worry that the screen may be faulty but if it was simply a feature of the technology then i would not worry.

any help would be great

I would check out how the Vizio handles SD if you're going to be watching much of it though.

plain football pitches etc are a good indiction. they are vertical lines.

however, i am going to be sending it from the same exact player connor has, hdmi and all. i guess i check in from time to time, and then see what it does for me when i actually do it.

I have no idea why a 1:85 movie fills my whole screen as there is no zooming being done from the set or the DVD player. I will have to check out a few more 1.85:1 movies to see if maybe it has something to do with the movie format.

I'm not sure if the PS3 has any settings regarding regular DVD zoom. I don't remember seeing any. I always understood that Anamorphic supposes to fill the screen so at first I thought the MacBooc was at fault but after seeing your post it seems the MacBook is doing a more accurate job.

Edited: I did some more checking and i think it also depends on the input and how the TV processes that input as in my case the PS3 is input via component and the MacBook is input via DVI. Via the DVI the input is native resolution so the TV doesn't do any processing on it but with component it does. I think it has to do with overscan but I'll let someone else take it from here...

As for Anamorphic, who knows what they actually mean there...I watched a 2:35:1 Anamorphic Star wars EPII DVD, and it definately had black bars without being stretched.

The CC transmission AFAIK is just for NTSC compatible signals and is sent over line21 VBI vertical blanking interval. The equivalent for this doesn't exist for 720p/1080i interconnects.

By interconnect I mean the connection between your source (DVD player, HD tuner, STB, etc.) and your display. Interconnects are normally component or HDMI/DVI.

The solution for this for was to encode the CC information into the mpg stream itself but this has the side effect that only the device that decodes the mpg (in your case the DVD player or HD tuner) has access to the CC information. Once the mpg is decoded and then needs to be transmitted to the display using component or HDMI/DVI there is no way to transmit it (ie there is no standard for the CC transmission over component/HDMI/DVI) Thus if there is CC information the source device needs to overlay that CC info on the picture prior to transmitting to the display over the interconnect.

In the case of the upconverting DVD player, if the CC information exists, the DVD player will need to be responsible for overlaying the CC info if you want to set the output of the player to 720p/1080i.

If your TV has a builtin ATSC/QAM tuner, then it is the one doing the decoding of the mpg so it will have access to the CC info and should have the ability to display in that case.

In short, I don't think there is anything broken with your displays, they are functioning as designed. I can see how it would be inconvenient and hard to understand. There are so many moving parts with AV these days it takes a rocket scientist to understand why things don't work as expected.

Can you check to see if closed captioning is passed to your Pio?
I am considering an Oppo 970 or 980, if it passes CC via 480i via HDMI.

I have a Pan 42px600u. and a wife with hearing loss.

resolution and the 5070 can display 1365x768. Will I notice a big difference?

thanks

This occurs after several hours (usually at least 4or 5) of viewing on an OTA connection. I think it may have occured with the DVD player as well but can't be certain. The set is not housed in a cabinet so heat build up is not an issue.
This blank screen occurs on most (if not all) channels not just one.When the screen goes blank, pressing the menu key does not bring up the menu. Anything to do with timers has been turned off including the TV Guide recording The VCR has been removed from the TVG setup. (The TVG itself is still programmed) To restore the picture a power off is all that is required.

I called Pio Support since the set is only 10 days old and it has been happening since day 1, and they said they have never heard of this issue and that no settings in the menus are likely to cause this. At first, I thought (Pio support concurred) that signal strength was the issue. But then I hooked my cable into ANT A and I am experiencing the same problem with cable, so I know its not signal strength. Even if it was signal strength, the video should come back after the signal strength is regained. The only way to get video back is to change channels.

I love this set, it has extreme resistance to IR/Burn-in, no bad pixels, no buzzing whatsoever, great picture quality, so even though my dealer will swap it out for another, I am hesitant to do so for fear I might get a set not as good as this one. I think it might be better to keep this set and let Pio replace the tuner module, which seems to be the culprit. Anyone know if replacement of the tuner module can be done surgically, i.e. (not have to take the whole thing apart to replace).

My set was built in AUG of 2006.

I was hoping, since I suspect that the problem is specifically in the tuner module, that that part could be slid out the bottom to avoid opening up everything, but it does not look like that will be the case. Also, I would not suspect the main video board because this is not happening on any other inputs other than ANT-A.
