Pan TH-42PHD7UY Black level changing - Page 6  

post #151 of 449

Visual Apex is not returning phone calls.
It does not look good!

Its a very difficult position to be in knowing that Visual Apex knows that there is a problem but cannot or won't take responsibility to exchange or repair my plasma! Perhaps they should change their return policy to state that once Panasonic confirms there is a defect they will accept a return?

I am caught between Visual Apex and Panasonic in the its not returnable until there is an "official" defect established by Panasonic. In the past Panasonic has not made any defects "official". In looking into the shutoff problems, some people have had success in getting Panasonic to help repair their plasmas and some have not.

Has anyone had success in fixing the WD7UY halo problems with the "blade fix"?

Jim,

Yes, The modified S-Video PCB has been tested and does help the blooming S and composite issues.

We're taking names (sounds like grade school) via PM and it is probable that exchange S boards will go out next week sometime.

This other issue is not so easy and I really cannot comment until there is some response from the factory. VA has been told NOT to comment lest they be misinterpreted so I wouldn't take it personal.

Any more at this point will need to be by PM if you'd like.

BTW Jim,

In our informal observations of various letterbox movies, we have not noticed any "strobing" effect or anything that would make the PDP "unwatchable".

You'll have to refresh my feeble memory as to what has happened up to this point. Is this the original PDP or an exchange still showing the same problem ? PM is OK to not clutter the thread.

Then maybe this guy has a bad plasma or defective unit? Why should
Panasonic have to sign off on something, if he says it's doing something wrong VA should issue him an RMA and let him return it.

It's one thing to return something just because you "changed your mind" but if the user is percieving to be a large technical problem the user should be taken seriously.

TW,

Are you saying you guys have not seen any brightness changing problems when watching letter or pillar boxed movies on the 42PHD7UY?

I found it quite easy to reproduce. It was irritating but not unwatchable. It does not happen on the 50PHD7UY.

Especially on OTA HD like Law and Order, I find that the density fluctuations are not only distracting, but just drive me nuts! I mean this is a very expensive plasma HD monitor and to have defect like this I guess just pushes me over the edge and made me wheel the Toshiba projection TV infront of the plasma until my defect is resolved!

I guess I am more sensitive than most, but the problem is easy for everyone to see.

Jim,

I fully agree it is a defect and needs to be fixed. I also didn't want to live with it. After all I found it irritating enough to negotiate a trade without the benefit of Panasonic calling it a defect.
post #158 of 449
Does anyone know if the 37" is affected?
post #159 of 449
The 37 is not HD, seems like only the 42HD shows this symptom.

The casual in shop viewing was in cinema mode, under avaerage shop lightning (not dark), default brightness (0) and picture (+10) settings and using Day After Tomorrow and Elf through S-Video from a DVD-2000 inductrial DVD Player.

Day After Tomorrow has bright ice scape scenes towards the beginning and then some darker scenes. The letterbox showed no distracting shifts but maybe it needs to be in a dark environment.

We did notice that setting the Video NR ON cleaned up a lot of the chroma crawl and dot crawl normally seen on NTSC signals.

We are still waiting for some factory response so I don't know any more at this point.

post #160 of 449
With respect to the brightness/black level change, as I've mentioned before, almost any episode of the West Wing in HD will do it - lots of very dark scenes with sudden areas of brightness moving into the image which inexplicably (so far) make the blacks go gray.

I think the "strobing" effect that is being referred to is rapid back and forth blacks to gray to black changes - caused when the action picks up, the camera starts panning more aggressively, the bright areas pop in and out of the scene, and the blacks go quickly to gray and back again. It really is very distracting, particularly if you were one of the poeple (aren't we all?) that opted for the Panasonic in part because of its great blacks.

I have the 50 7UY not sure if it's this thread or the genral 7uy problems thread is the right spot. But I now just started noticing it in my 4 month old plasma. I don't think it was there before. In particular I started noticing it in West wing, and law & order. But that bright/dark strobing effect is apparent. HD-tivo connected via component. I thought only s-video was effected. I get it on my vga input as well where i Have a vga to component video cable connected to my dvd player.

Is this an overall defect of the panel or will replacing the input blades fix it"?
post #162 of 449
Unlike the s-video problem we don't have any information about the cause of the changing brightness issue. Since it happens irrespective of input changing the input boards isn't going to address the problem.
post #163 of 449
This is very concerning as I am about to pull the trigger on the 507UY. I thought the 507UY was fairly immune to all problems except for the s-video blade. Weird that you never noticed it until a few months later. I wonder if it was there all the time or has something changed. Now what?
post #164 of 449
I'm pretty picky about the picture. I'm pretty sure the problem wasn't there before, I would have noticed. but who knows I might have just been so damn excited to have it and subconsciously let it slide. but it's definitely there now.
post #165 of 449
First confirmed 50PHD7UY on the forum with the black level problem. Interesting begs the question if the problem on the 50 develops over time or whether it was there to start and you just didnt notice it. Enuf of a concern to make me pause on buying decision that was headed in the direction of the 50.
post #166 of 449
gadgetfreaky,

Can you post your picture and brightness settings of your display? Doublecheck to make sure Automatic Gain Control is not enabled.

post #168 of 449
I was thisclose to buying a 42HD7UY until I saw this thread. While I'm sure the vast majority of people purchasing the 7UY sets know nothing about these problems, reading about them here caused me to pull the trigger instead on an NEC PX42-XR3A. Not sure how much business Panny is losing over this but they certainly lost mine.
post #169 of 449
I was very seriously considering the 50UY particularly since the price drop put it within shouting range of the DLP / LCOS options I had previously considered. Having been burned by the DILA (2 sets broke down on me) I was thinking to go the tried and trusted route with a Plasma. Now I see this thread and feel I need to start shopping alternatives again. Why isnt there a compelling trouble free HDTV option out there?
post #170 of 449
My 50UY has been working very well for me. If you need s-video there is a fix available. I understand people shopping elsewhere, but I've been very happy with it.
post #171 of 449
Re the 50 and one or two 'black level changing' reports. From all the threads and what I have read, they did not (at least noticibly) have it new out of the box. Doesn't that mean it is a defect or problem that would be covered by warranty (easily if during the first year - a bit more difficult through a third party warranty or credit card extension warranty)?

It would seem to me that if it was noticable enough to warrant calls for a warranty fix Panasonic would come up with a repair or replace the unit. They probably wouldn't admit or publish that there is a problem but would fix it for 'the squeeky wheels'. Since it is hopefully intermittent and not a design flaw it would make sense that they fix the issue for the small minority of people having the issue to avoid the bad press. Any opinions would be helpful to an anxious prospective buyer like me.
post #172 of 449
so did anyone got a solution w/ VA about what they'd do if a customer receives a Panny w/ one of these known problems?
post #173 of 449
Hello,
Today I ordered a TH42 (ED model) from VA. After reading these threads and learning about no calls or emails returned from them, I am going to cancel my order and take my business elsewhere. It hasn't shipped yet and I'm going to make sure it doesn't.
post #174 of 449
Here is my cancellation letter to VA:

"Dear XXXX,

Please cancel my order for the Panasonic plasma. It has not been charged to my credit card—and it has not shipped. From what I understand and I have read on the various video forums recently, there exists a defect in some of these models. More specifically, it has to do with dark level fluctuations while watching material.

I also have read where your customer service representatives have been un-responsive to some of these folks that have purchased from Visual Apex in regards to this problem. Most notably calls not returned or emails ignored.

Although you’ve been personally considerate with my order, I can see that there may be a problem in the future that may cause some difficulties working with Visual Apex regarding Panasonic plasma models.

Sincerely,

Clint Thayer"

I think this problem was mostly (or only) on HD versions...

What led you to that conclusion? I've not seen anything that would indicate that. Did I miss something?

Nothing has changed yet on the HD7UY situation.

Still awaiting word from Panasonic and Visual Apex.

Waiting quietly but time is running out!

Here is the letter from VA regards to my cancellation. I noticed a bit of sarcasm at the end of the letter:

"We will process your order cancellation this morning. Just for your info, DHL includes DHL Danzas which is located by Seatac and it's where our products are warehoused and their number is 800 426 5962 and info on tracking through them can be found at

http://www.visualapex.com/ship/defau...ppingCo=Danzas

As for the forum - it's just that; a place where 1 in 10,000 people can sound like 10,000 people and it's up to individual's to filter out the fact from the hot air. Yes, there is a perceived problem with the Pan 42PWD7 and Panasonic has worked out a solution for the people that need one; I have a Pan 42PWD7 and i don't use the s-video input. When I do, I know what to expect and it works great for me.

But be careful what you take as fact from the forum and consider the source. We've somehow managed to please 10,000+ customer's over the last 6 years and we've done so by being responsive - this includes sending out emails at 3:30 in the morning to customer's requests to cancel orders.

Good luck with your search.

Sincerely,
XXXX "

I think that's a fair response on their part. They're getting a lot of heat on this forum from a few people. Those people have legitimate issues, but we're not hearing about all of the people who are very happy with their service, even when they've had problems. I'm one who has had problems and was satisfied. Once choice I made was not to wait for a resolution that I was certain would take some time. My blood pressure is lower as a result :).

Do I think they're perfect? No; the comments on this forum by one person who works for them were a bit substandard in my opinion. They struck me as a person who isn't used to pacifying angry customers, who after all tend to be a little belligerent because of their frustrations.

But they have followed through on the s-video issue (even for frustrated customers :)) and have been working with Panasonic on the 42PHD issues. I'm sure that once there is a resolution to the 42PHD problem that they'll work with their customers to get it implemented. Jim (jadolley) is waiting for that day. Until then they're in a situation where they've been told not to say anything; all the while people on this board continue to say things about them while no one says things about the many other vendors who sell the same displays that have the same problems. Tough spot to be in, but that's the cost of doing business sometimes.
