Here's another one.
I've got a 50" panasonic plasma 50phw3u and standard components well here's the list. Onkyo 797, Panasonic rp91, echostar 3900, pansonic vcr, sony cd, onkyo m282 for dist audio which is plugged into the back of the 797 switched outlet, and soon to be motorola digital cable with decoder. Also using the Monster Power HTS 2500.
The disappointment here is every image displayed. Th ebest being the DVD that's connected via component, then the sat connected via S-Video, then the VHS connected via composite. The sat and VHS are routed through the 797 while the DVD is connected directly to the plasma. ( didn't want to take the chance of any signal loss going through the Onkyo, although once the HD cable is added I won't have a choice but to use the component video switching of the 797. )
Back to connections, the component input of the plasma is BNC, I used BNC to RCA adapters to plug in standard RCA component video cables from the dvd.
My biggest complaint is that while watching Star Wars the Phantom Menace any scenes that are slow moving and the colors are light such as blues and whites primarily, the image is fuzzy. Not the entire picture, just where those colors are. It sucks. Now what's wierd is while playing a setup DVD by panasonic ( I realize this isn't choice software, what should I use ) the images looked much better, clean and sharp throughout the spectrum. Granted most images where still, but looked great. Even the blacks which Panasonic seems to be proud of and should be in my opinion.
Why is it that I get the fuzzy images in some scenes of a movie but yet the setup disc looked great. Is it the Recordings of the DVD's, or simply a setup issue??
Yes the progressive scan is turned on on the DVD player.
Speaking of setup, in the menu of the DVD setup the option for type of display is available ( which I assume is pretty standard for higher end dvd players ). There was no option for plasma. The choices were crt, lcd, direct view, rear projection. ( if I remember correctly ) Of those options the CRT was the best so that's where it is.
Hopefully this is thorough enough to aid with troubleshooting.
Thanks in advance,
CMack

Is it mainly in action sequenses ? Plasma IMHO do not look as good as they cost , even at 3000 retail I have been seeing. I have yet to see a plasma I would purchase for myself.

The setup disk looks right because IT"S A STATIONARY IMAGE.

Hmmm... Without any objective way to closely evaluate a plasma long-term, my mind goes back to all the action sequences I've casually walked by in dealer's viewing rooms; nearly always the ballet, slo-mo divers off of clifftops, a slo-mo Dolphin at a marine park, and a slo-mo basketball game, and also a hockey game. Only interrupted by a schill for the plasma Mfr. who stands in one place and feeds you propaganda on how great it would be to free up the floorspace. I'll have to ask for a "known" movie sometime. I haven't scrutinized one closely because I'm still Ebenezer Scrooge on the price. Mebbe' I have to veer down the path that I've known all along was correct: FRONT PROJECTION!

No, It's primarily when the images are still and focused. When the movement is fast you don't notice.

Are you seeing plasma flow ? Are you too close to the screen ?

Explain Plasma Flow. I'm not familiar with the term.
The screen is 50" and the seating is 12' away, and yes it is less noticeable at seating position but not acceptable.
Thanks,

I would suggest calling an expert that is located in your area. Posting for this type of problem on a website with out someone actually seeing it is very hard to diagnose. If there is a way to fix it then it may require special equipment which once again the ISF guys are trained for and have. Getting the best picture from your display is what they do. It makes a huge difference in PQ.

I've used some plasmas and do not think they are ready for market even now. The contrast isn't that great (but much better than 5 years ago) and the fuzziness you talk about is pretty natural except for the ultra high res stuff...

HEY MATT,

My ISF guy happened to be over today to fix a green issue. He told me that RP's can still give better PQ then a plasma.

How many ansi lumns ? What is the contrast ratio ? Which Plasma ? Try adjusting the blacks to blacker ?
Check your contrast ? bad video wire or connection ?
Use crimp or solder on bnc one end and crimp or solder on rca's other and use beldin or better rg59 ? GOOD CONNECTORS(kanari , king , etc.) NOT RADIO SHACK

I don't doubt him at all - at this stage Plasma is a trade-off for convenience.

cmack,
I had the exact same problem you are discussing with a NECMP51. Although plasma is not a perfected picture, this model did not compare to others we had mounted. We actually pulled this one down and replaced it with a Fujitsu model which the customer loves. We actually brought the Fujitsu model over and held it below the NEC for a real comparsion. The NEC could not touch the picture of the Fujitsu. I talked to NEC, let a tech look at it and they claim that it was fine. Anyway point of story, Still have a NEC in stock.

Yeah, the Fujitsu is probably the best I've seen. And I agree, a RP is a far better picture with normal video input.

As for a solution I don't think there is one in sight. What I mean is that this is as good as it gets with the exception of having an ISF tech square it away. Still from all my homework and responses to this thread, I think it's just the nature of the beast.
One thing I'll add is after going in depth of the setup on the Pan RP91 DVD, I did get a better picture and the client is happy. That's the ultimate goal.
As for my taste, it will be a while before I invest in a plasma, and for more reasons than just the picture quality.
Any recommendations on setup software? Believe it or not for the first time I went into the THX setup on the DVD The Phantm Menace and during the video setup it mentioned the use on THX color glasses of some type. Is this something that should be used for setup or not.
Thanks,
CMack
