First post, and it's very much one of desperation. Let's just say I'm looking forward to the opportunity to purchase one of Dane's PMCv1 devices. My TC-P42S1 apparently crossed another black level threshold this evening and it's now terrible. Black doesn't really even exist on this panel anymore (see pic taken earlier this evening, no signal on an HDMI input in a nearly dark room...utterly pathetic). I have to get another 5 or 6 years out of this TV and can't afford to chuck it--which I most certainly would if I could spare the money for a new set. I'll never buy anything from Panasonic again (though if I understand news reports correctly, that may just resolve on its own).

Anyway, thank you Dane for your efforts and hard work on this! I'm sure there will be a lot of happy Panny owners as a result very, very soon.

I checked hours today on my set...it's closing in on 11,000 and based on when I purchased it, it averages about 6 hours of operation per day.

I just resetted my 50G10 using Mironto's method and its like day and night.
I will probably still buy Audiodane PCM's has its a more automatic solution.

Here's the before and after pics taken in my dark basement with no flash on camera.
I should've put an 1080p movie but i was in a rush to reset my panny...

That looks so bad, just like mine. If it looks like the ST30 I have I'd be happy. I think those two are spec'd at about .008ftl and this thing is looking like the .028 or so that's been reported, what a shame. Anyway, thanks for the pics. That looks nice!

Hi. I reset my 50VT20 using Mirontos guide this weekend.

Went down to 0.005 ftl from 3x that high. Thanks for the great help on regaining a new TV!

The only problem is I am now seeing the floating black problem of the VT20 2010 model. When the screen is dark the letterbox bars are reading my new blacks, but when a brighter scene shows the blacks float up to 3x higher again.

I will have to search for a fix to this probl now. On blank output though I have achieved a 3x reduction in MLL from before to after.

Great stuff and thanks for the help Mironto

Hi. 50" pretty close to your quoted number from new. I am using i1d3 oem. Could easily be measurement difference.

Hi, Here is my set up for the VT20 with the smaller GH connector in the attached photo. Pretty small to work with so I had to use the very small gauge wire and splice it with the jumper wire male ends. Seemed to work. I did have some trouble reading the values from the software but the scripts load up fine and seemed to do the job. I do not think my wiring job is very robust, but managed to get the result. Thanks for all the excellent research the people on this thread have done.
