I would like to express my greatest gratitude to everyone here, but especially to Audiodane.
I'm the owner of a 2010 TX-P42GT20E, who is displaying a clock of 16200 hours, and whose black levels have raised exponentially in the past months. They were bearable in the past but past the 15000 hours clock it has just become extremely ugly. It seems there is yet another increase around that time, and that one is incredibly big. I didn't notice when the others happened. I did with this one.
I wanted to try the DIY way with a Raspberry Pi but somehow couldn't make it work, I only got a red blinking light on my TV when plugging the stuff on, after disabling the pull ups/downs on the I²C pins of the RPi... If anyone has made it work with a RaspBerry, I will be glad to learn from his/her experience.
Not to mention getting the 11 pin JST connector for the 2010 model was a pain in the ass alone, I really didn't want to break my TV because I made a mistake.
Now, I plugged the PMCv2.2 that I recently bought from Audiodane. I have to admit that even with the 50$ shipping (yeah, that's freaking expensive) to Switzerland, I'm absolutely not regretting the decision to get this device. I was so afraid it wouldn't work and that it would give me the same blinking red led error as with the RaspBerry.
Turned on the TV only to notice... that I didn't see anything ! Room wasn't dim enough for me to notice the panel was on, when it literally lit up like a LED panel just seconds earlier ! Also, as a simple remark, the screen didn't have to be reset when the timer was reset, I just turned the TV on and it was done.
This is an outstanding work that you all did, and I'm seriously glad that some people dug into this problematic and actually found a solution that's literally plug and play !
I would like to reward the original researchers, clktmr and markone, for the research they put into this. If I had any chance on getting their paypal addresses, I'd be glad to pay them 20$ each, because let's face it, they deserve it BIG time. As for audiodane, he'll be getting a few other orders from some of my friends who also have the same plasma TVs
Congratulations to all of you and a very massive thank you !
