As an aid to people considering the purchase of this (or like) sets I thought I'd post my experiences.
Although these sets availability is waning as the new models come in, these comments may (or may not)
apply to newer Panasonic models. Or they may only apply to my set (which is part of the reason I'm
posting). As a further goal of this post, I do have some remaining questions/problems
with the set. Any comments/suggestions would be appreciated. Although one of my main concerns remaining
is probably well known on this forum (aspect ratio), I couldn't find the second anywhere and thus the new thread.
In order to let everyone know from what perspective I'm coming from...a bit of background...
I bought my Panasonic PT-47WX42 about a month ago. This is my first experiment with rear projection, so take my comments as coming from a newbie. My main use for this set has been DVD viewing. It has been paired with a Sony DVP-S7000 mainly but also
with a Panasonic RA60. Video has been sent from the DVD to the TV over S-Video and Component (more about this later).
After purchase the TV went through several quick AVIA calibrations. After a month, I'm left with the impression that I still have a bit too much red in the picture and the contrast is not quite right. However, I'm still really pleased with the look of the picture. Some user convergence was needed but it was very easy. I found the remote and menu system while not award winning...usable and clear.
So in the future I'm going to tweak it some more and hopefully get the picture more to my liking. However it appears to me that the more I look at the screen, the more I believe that I'll eventually have the TV calibrated by somebody who knows more than I or go into the service menu myself. I still haven't found enough detail to attempt this yet (at pannytv.com and other links that have been posted to aid us first timers). In any case that is in the future.
The two main comments I have with my experience (beyond picture tweaking needs) are...
1). 3 vertical bands of lighter/darker darkness through
the component input.
2). The aspect ratio is incorrect.
I'll explain 1) first. My only Component Cable used is a Radio Shack AVFusion 6ft cable. I bought this right after the TV. Upon switching to the component cable from the S-Video, I noticed these 3 bands in dark/black sections of the picture...or between menus and movie when the picture goes black. The bands are not visible in 'light' areas of any sort...just black. They are not very noticeable as well in a room that isn't nearly dark either. So please don't get the impression that these bars will jump out at you. The bars are not visible through the S-Video cable.
So back to the store went the Component Cable, and I returned with another of the same make to see if it was a faulty cable. The bars were still there (although to be honest they seemed reduced). The bars are also present when using both my Sony S7000 and the Panasonic RA60. So in an unscientific way, I haven't tested another form of component cable, but I'm thinking this isn't a cable problem.
The only mention I've found anywhere about something similar to this issue was over at DVDspot (I think). It was mentioned by 'mic' (sorry if I've gotten that wrong) that he thought that there was an incompatibility problem through the component connections of the previous model year Panasonic TV (47WX49 I think) which I'm guessing is similar to my TV and DVD players with automatic black level. I can't say I know whether my DVD players have 'automatic black level' vs non 'automatic black level'. The RA60 has a black level menu item which I can vary, but whether this then means non 'automatic black level' or this definition is dependent on the inner processing I do not know. Mic mentioned that the Panasonic 82 (I think) did not have the problem. As I will be upgrading to a Progressive Scan DVD player sometime in the near future, any comments on what players have/don't have this incompatibility would be appreciated. Also what about automatic black level may cause this? What is automatic black level vs a user menu of black level?
The second remaining problem is that the aspect ratio for movies is not correct. My picture appears 'taller' then it should be. People appear somewhat 'Close Encouters'ish. If I measure the movie screen dimensions on a 1:2.35 movie, it measures more 1:2 (much smaller black bars then should be there). Obviously on 1:1.85 movies I'm losing picture off the top and bottom. I first thought this was some sort of overscan problem. In AVIA it appears I have 5% overscan on all sides. But as I understand overscan...I don't see how it could change the aspect ratio. I guess my new theory is that somewhere in the service menu is a 'vertical stretch' button that is off? Just to head off a couple responses...the DVD player has been set to 16:9.
By comparing the picture on a normal 4:3 set to the Panasonic, I'm losing about 15% of the vertical picture off the top and bottom...and very little of the horizontal...probably about 5%. So far this stretching hasn't been too bad for my enjoyment of the movies. I find this much less noticeable then if the horizontal was stretched which I've tested by changing the DVD output to
4:3.
Again any comments would be appreciated on whether the problem is something that is 'fixable' in the service menu or if this is a much bigger problem then I am hoping.
To wrap up (I know this was way too long), I'm very happy with this set assuming that eventually I can remedy the two above problems. Whether I would have been happier with another set with fewer or different problems...I won't know for a number of years when I get more experience with different sets. My comments should not necessarily scare people away from Panasonics, but I think the information should be out there somewhere (and I was not able to find it with searches on this and other sites). I plan on keeping this set for quite a while and am having a great time with it. Tweeking is part of the fun after all...
Any comments or discussion would be welcomed.
