I have the Zenith SAT520 connected via DVI to a Panasonic TH42PA20 plasma (which does accept 720p over DVI).


When 1080i output (native or up-converted 720p) is sent via DVI, the picture is shifted to the left approximately 1 inch. This is very obvious when the "info" or "guide" overlays are displayed. 1080i output through either the VGA or component interface is correctly centered.


I would like to find out if others are observing the same abnormally with the SAT520 or its HD200 clone with the same display or other displays, and get an opinion on whether the Zenith receiver or the TH42PA20 needs to be adjusted (which service dept do I call).


Thanks

Interesting. I have the HD200 connecting to a Samsung HLN617. Originally I had a HLN4365, and when using DVI to the HD200 with that set, 1080i wouldn't display at *all,* let alone offset. On my 617, though, it now displays properly (perhaps because of latest firmware upgrades.)


On both the 4365 and the 617, though, if i use the VGA out from the HD200, if offsets the images (actually squishes it) to the right by more than a few inches. So that's the opposite problem from what you have.


Sorry I couldn't help more, but it sounds to me as if it could be a display issue handling the 1080i signal than it is a STB issue. Just a guess, though.

Swee, I noticed a similar problem when using the DVI input on my Hitachi Plasma TV. The Hitachi has controls in it's advance picture menu that you use to adjust both the horizontal and vertical position of the picture. Your Panasonic should have similar controls. It may also contain some sort of auto adjust mode that does this automatically. But be sure to check your TV manual: mine warns that you should allow the set to warm up for 20 minutes before performing auto adjust. I hope this helps!

My Mitsubbishi 55413/hd-520 combination started shifting to the left last night..

Using ez-dvi with a Monster DVI-d single link cable...

The Directv HD channels are normal.

Over the air with a Silver Sensor Antenna..

4-1 normal

5-1 HD feed normal but at commercial break with a 4.3 feed the display shifts left and then shifts right with the return to a HD feed.

8-1 N/A this a VHF channel in my area, no antenna yet.

11-1 HD Always shifted left

13-1 HD Always shifted left


I switched over to the DTV Component cable connection and there is no shifting, but I lose the stretch - plus format,,

I have a Pio plasma with the Aurora A303 digital card that provides a DVI input into the plasma .


I noticed there was a firmware update to the A303 card that mentioned fixing a problem with the 520's dvi output.


Supposedly, according to Pharris, the 520's output is high gain or NOT quite within the specs it should be in some fashion.


I wonder if this is what you guys are seeing.


While the 520's is still the best OTA HDTV tuner and I love it the total fix list for the fimware updates and this dvi issue probably are just indiciative of it all being new technology.


Anyway the point is, this "high gain" issue with the 520 dvi output might be your problem.

Does anyone know what is the most current version of firmware/software in the HD sat 520? My ez dvi will not synch with my InFocus 7200 and some have suggested that a "new" firmware helps? Any ideas on how to get the new firmware?

520 current version is 1.04


and there is a pdf link on this board with all the fixes and a 520 thread with the fixes spelled out one by one

I have the Panny pa2ou with the Pioneer 3510 HD box and also have the picture shift to the left.

See http://home.comcast.net/~sweeboonlim/all_3.jpg for pictures that illustrate this problem. Since the original post, I was able to manually force the TH42PA20 to offset the 1080i image to the right. The problem is perhaps not an offset problem, but rather the right part of the image has been clipped.


Picture 1: This is the 1080i component output image showing the guide overlay.

Picture 2: This is the 1080i DVI output image. Notice the outline box around "Sep 13" is cut off and there is a lot more empty space on the right.

Picture 3: This is the same 1080i DVI image, but with offset to right added manually by adjusting the VPOS setting of the tv. Notice that the left side of the outline box around "Sep 13" remains clipped off. In fact, the left side remains clipped off even if I remove the guide overlay. Removing the guide overlay usually shows more of the image beyond the borders of the overlay.


There are two possibilities. The output from the SAT520 was already clipped or the tv DVI input did the clipping.


I am posting the pictures so that others having problems can compare what they are observing. If the same behavior is observed on multiple different tv/monitor models, then it would be reasonable to conclude the SAT520 is the more probable suspect. On the other hand, if the same behavior is observed with different 1080i DVI sources, then the TH42PA20 is the more probable suspect.


In any case, I have a replacement SAT520 coming from Zenith/LG and have scheduled Panasonic service person to check out the tv as well.

Swee,


I have a Samsung DVD-HD931 connected to my TH-42PA20 via DVI. When I have the player set to 480P, the image is centered on the display. When I have it set to 1080i (which gives me a better picture) the image shifts slightly to the left. So this might indicate that there is a problem with the panny's DVI while running 1080i.


Though I don't have a PC connected to my display, is there a way for me to use the VPOS to shift the picture?

 

[Swee]

How much does it shift? Can you provide an estimate in inches.


In the case of 1080i DVI from SAT520, it is not just a shift problem. The left side is totally clipped. Even if I shifted it right, there is no content to the left (see pictures linked).


If the shift is minor, you can correct it in the service menu. However, I believe (from experimentation) any changes apply to all 1080i input (whether component or DVI). If you have a component 1080i source, you may want to check that it is also shifted before applying the correction for DVI.


Instructions for entering service menu at http://www.calanan.com/panasonic/?KeohiHDTV works.


You will need to apply 1080i correction with a component 1080i input since Panasonic does not allow changes to settings with DVI input. The changes you make with component 1080i input also affects 1080i DVI input.


As always, write down the original values and enter the service menu at your own risk. Best of luck of your tweaks and keep the group posted.

Swee,


I say it's shifted about two inches, but is only noticeable when the credits, or some type of writing is on the screen.


I also use a Samsung TS-160, and that was also shifted to the left, but there's an adjustment available in its set-up menu, so that's not a problem any longer.


The Sammy 931 has no such adjustment, however Samsung has offered to service it to correct the problem.


I'll see if that helps before I enter the Panny's service menu.

Arnie,


The problem you have observed is explained at
http://www.avsforum.com/avs-vb/showt...13#post2668713


I just got a HD931 as a second 1080i DVI source to test whether the 1080i DVI problem is the TH42PA20 or the Zenith SAT520. If you have the updated HD931 firmware, selecting DVI mode A solves your problem.


However, the question remains whether the problem is with the Zenith SAT520 or the TH42PA20. Since the HD931 ships with DVI mode set to B and the original firmware supports mode B only, I am inclined to think that the TH42PA20 implementation is not as compatible as it should be out of the box.

 

[bocktar]

I use the SAT-HD200 and think it's important to note that when the guide is up, (on a 36" 1080i 16:9 display) the STB outputs the top 1/4" and right 1/2" of the picture as solid black. It does not do this when the guide is off.


This may explain why you're seeing a more pronounced shift when the guide is up.


Regardless, it sounds like you have a slight horizontal positioning issue with 1080i sources that can be fixed with calibration. Just make sure to calibrate your set with the guide off. You won't get the results you're expecting if it's on.

Swee,


Sorry I didn't get back to you sooner. I have visitors from out of town.


Thanks for that link. As soon as I get a minute, I'll switch the mode from B to A and see what happens.


Sure sounds like there is some compatibility issues with the TH42PA20 out of the box.

I'm going to be upgrading from the TS-160 to the new Sony HD-300 as soon as it comes out. Of course, I'll be interested in seeing if there's a compatibility issue there as well.

Forgive my ignorance here....How is that compared to the 520? Does that mean because of the multiple types that the geomentry problems with the Panny and the STB will be mute with the 3200? (The afore mentioned problems anyways)


Thanks!!!!

The previous model support A, B, C, D, and E. The "i" catagories were added for in the new models.


A = 1080i, 720p, 480p

Ai = 1080i, 720p, 480p, 480i

B = 1080i, 480p

Bi = 1080i, 480p, 480i

C = 720p, 480p

Ci = 720p, 480p, 480i

D = 480p

Di = 480p, 480i

E = Not classified by above

 

[Arnie D]

Swee,


Changing the mode from B to A on the HD931 shifted the picture to the right, and into the proper position. Thanks. Don't know how I missed that thread, or reading it in the owners manual.


Of course, when I initially called Samsung about the problem, changing the DVI mode was never mentioned to me. They just said, "we'll e-mail you a shipping label, send the player in for repair." They're apparently more clueless than I am on the matter.



Thanks again.

JFerg,


Thanks, that's good news.


Anything new on the release dates? Is there a slim chance that the LSS3200 will be available before the HD300?
