Wow... just happened to check back

I have a 2009 46S1. Is that covered ? (12G ?) So I can look forward to restored black levels ?

You never knew? Same here. But I bought a 60" ZT and then checked this forum and saw where a solution had been found.

Yes. I've done the reset with a 2009 S1 and it worked wonderfully.

Thanks for finding a solution. Amazing. What's the latest estimate on when the device will be available ?

Could be. I do not believe for one second though that a 60U could have a 0.012ftL MLL (that's lower than the 700U's on the chart!). I am only using an i1 D2/LT so I don't claim to have the most accurate results, but I have seen others on this forum corroborate the ~0.03ftL MLL measurement for 9G/10G Panny's.

AFAIK there was a big step forward with the 11G models in black levels, the 9G and 10G were pretty similar to each other. Corroborated this with my own experience -- I had a 600U, now have a 10UK, my friend has a 9UK, and my brother and parents have 11G models (PZ80 and PX80 respectively). So I have plenty of time with all of them. The black levels on the 11G's are obviously better when the room is darkened.

I will try to go take measurements of my friends/family's sets though and see if they pass the "smell test". I could certainly believe that my i1 is starting to lose it a bit...

EDIT: here is a summary of the published measures from HT Mag on Panny plasmas...
http://hometheatermag.com/plasmadisplays/index.html

Code:
42PX25 ---- 0.027 ft-L42PX500U -- 0.027 ft-L42PX60U --- 0.012 ft-L42PZ700U -- 0.015 ft-L50PZ700U -- 0.017 ft-L50PZ750U -- 0.018 ft-L50PZ85U --- 0.010 ft-L50PZ800U -- 0.013 ft-L65VX100U -- 0.005 ft-L42G10 ----- 0.014 ft-L46G10 ----- 0.009 ft-L58V10 ----- 0.005 ft-L

To me the 60U measurement sticks out as an anomaly.
Anyone think the 50PZ85U --- 0.010 ft-L is an anomaly too?
I just measured my PZ80 because I thought the black level has gotten worse, and got 0.017 ft-L but it has 4000 hrs. So I don't know if this is just normal, expected due to age or I have the rising issue.

As I posted just a couple days ago, my wife was in the hospital for 6 days with blood clots in her lungs. Before that we were in Las Vegas for Blackhat and DEFCON hacker conferences, and before that a week at the beach for a family reunion.. And on top if that I swapped the red and green LED's on the board and had to ship them back to be repaired-- so I've had precious little time to work on it. But I am through with travel and my sweet wife has been given back to me and I'm anxious to get back to the PMCv1! Mondays are my usual PMCv1 days, and I expect this coming to be no different. I am even going to TRY to squeeze in some time this weekend if possible.

I am so encouraged and grateful for the well-wishes received here and on the website. Thank you all for hanging in there after delay upon countless delay. I agree that September sounds very realistic. The TV connectors all arrived today, and the LED's are fixed-- everything I need to build 100 complete units is finally here! Upcoming tasks include verifying the code works on the new hardware (including undo), and creating a verification method to TEST every unit before shipping them out.. I have some ideas that are faster and easier than hooking each one up to my TV, but I don't know if I want to wait that long-- I may just hook each one to my TV for now to get things moving.. I'll be giving that decision careful consideration in the coming days.. I want these things ready as much as y'all do!

Thanks again to everyone,
..dane

Well, I gave up and bought a Samsung plasma. Won't be needing this anymore but good luck to those who do. Black levels on the new set are a night and day difference from my post rise 50S1. I didn't realize just how bad it had got until seeing them side by side. The Panasonic looks like a cheap lcd in comparison.

I don't miss those fans on the back of the set whirling away either. I thought it was just my computer fans making noise but the room is actually much quieter now.

Black levels on my very-well-used 58V10 are pretty bad. Will definitely order a unit assuming it will work on the V10.

Off the top of my head, don't think an exact price has been established but shouldn't bust the bank. I'm thinking $30-$50 but don't quote me on it.

Thank you.

Just incredible that there is a fix coming soon. I don't know why I even checked back on the thread but sure glad I did.

I have a 46S1 and I'm very excited about restoring the black levels.

Same here. I gave up years ago and learned about the fix when I came on AVS to research a ZT. Purchased the ZT and realized how bad my blacks were. Then I rediscovered this thread. Waiting like everybody.

Just checked audiodane's website to see if there were any order updates, and there's an "account suspended" message up. Hope that's not ominous.

Hello,

I am going to give Mironto's guide a go on my New Zealand 50VT20. Once completed I will still be very interested in the permanent solution too as I will then be able to set and forget. I have my Arduino board now but am having trouble getting hold of a 13G 2010 model service connector in New Zealand. I can order the part from the link provided in the guide, but it costs me $39 shipping for a 25c connector. NZ is a long way I admit, but still. None of my local stores carry these connectors.

I would be happy to give the jumper wire technique a go, but the 2010 service 11 pin connector looks much smaller and difficult to simply join the female jumper to, compared to the 2009.

I might have to ask the local panasonic TV repair shop if they know where I can source one locally.

My blacks are measuring at 0.06cd/m2 or 0.018 foot-Lamberts. Thats at least 6 times higher than my 65VT50. I am very keen to see if I can get back to the original performance. I am not even sure what the VT20 model was out of the box for MLL

Managed to source a connector and crimps from Singapore supply and free of shipping for my first order. I did have to order 10 connectors and 100 crimps minimum but what can you do from NZ?

A $17 investment, but by mid next week I should have all the parts needed for the reset.

Hopefully I can have original blacks on my VT20 by next weekend.

In the meantime I am enjoying the VT50 with 5800hrs with no rising blacks so far. It will be very interesting to see how the VT20 compares to it with a fountain of youth

Audiodane price estimates are very good when I look at my connector part prices above and then the board parts and then jumper wires etc.

Not to mention his solution is self managing for a longer term.

I will still be looking at this project as proof of concept and then will be very interested in the Audiodane model for the long term.

It's just an awesome project to help is all out.

Thank you all for the kind words, and concern over my wife's recent hospitalization. Coming off the hacker conferences in Las Vegas earlier this month and then a week in the hospital followed by a half-week mission trip to Guatemala (of which my wife had to give up her seat and stay behind while I went ), and the cold that I apparently brought back from Guatemala (but thankfully no stomach issues) has all been detrimental to the PMCv1 timeline. Everything is slowly returning to normal but I'm now way behind at both work and home (scouts, mission group, etc) ..., it's absolutely insane.

I was checking my emails today to setup an auction snipe on a DVD series for my kids and found a half-dozen emails from my website's hosting service! Apparently the renewal that I submitted to them earlier in august was only for the domain name renewal, and did not include renewal of the hosting service itself. Whoops!!!! Thankfully they only suspended the account and did not erase everything (but I do have a automatic backup to dropbox that I could have restored from), so as soon as I paid the renewal (and the late fee ), everything is back online.

A phrase my co-worker uses comes to mind this week.. "Nothing is so easy that it can't be made nearly impossible to do." Seems there is some serious resistance at play to my progress on these fronts.

So, where are we today? I already have over several thousand dollars in material costs alone committed to the PMCv1 boards that are sitting at home. *NO ONE* is more anxious than I am to get these bad boys up and running. I assure you that while delays may continue to occur, this project WILL see completion.

I am grateful for the emails of support and concern for my wife, and of course the continued interest in the PMCv1. I promise that I am working as hard as I can to get it done. All that is left at this point is to figure out an easy way to "self-test" each unit before shipping them out without plugging in every single unit to my TV. (That might wear out my own TV's service connector, and then I'd really be up a creek without a paddle.) As soon as I can self-test each unit, I'm ready to put up the sale page.. Doesn't sound like much, but that phrase from my coworker comes back to mind..

And another phrase we say around the office: "All ya' gotta do is ........"

cheers,
..dane

Thanks Crudesinger .. Price for the first 98 units will be USD$60 each, free shipping to "lower 48/CONUS." Outside the 48 states will incur additional expense (TBD). That additional shipping fee is the lowest priority on my radar right now, as it can easily be fixed by using the eBay International Shipping Program for a small nominal increase (maybe USD$10?).. That seems an easy and simple solution for now, maybe a better one will come along later..

Your second point above is also appreciated; there is some "value" into the time and sweat that I've put into this automated approach, above and beyond the cost of the physical goods. I think the $60/ea price is reasonable, considering its job and its cost in relation to a new TV..

cheers,
..dane

This is odd…

Quote:
The question on everyone’s minds, of course, will be whether or not the new NeoPDP panel can match or even exceed the deep blacks produced by the discontinued Pioneer KURO displays when viewed in an entirely dark environment.

The answer to that is: very nearly. The Panasonic TX-P50VT20′s black level measured at an astonishingly deep 0.006 0.009 cd/m2, making it the deepest that Panasonic has ever produced, albeit minutely higher than Pioneer’s best (which we measured at 0.003 cd/m2).

Quote:
The corrected black level measurement is 0.009 cd/m2, meaning that, just like before, the Panasonic TX-P50VT20 produces an incredibly dark shade of black which is second only to the Pioneer KURO displays.

Thanks for the update. No rush for me, I replaced my V10 with a 60" ZT. But I know others are very anxious.

Glad your wife has recovered. Keep up the mission work in Guatemala which is way more important than our TVs. And I've got the same cold. Going on 1 week and can't seem to get rid of it!
