I can't believe how good this 2008 model TV looks. It is for the living room, not my main system, where viewing angles are very wide. No LCD can touch it.

I installed the PMCv1 on my 54G10 and restarted the tv, I had to slide the two switches to get rid of the red light. Wow what a difference! It was pretty unwatchable in the dark or with dark content. Now neither is a problem. Thanks audiodane and mironto for this fix. Yet another happy customer!(unit#23)

Glad to see that the "black resetter" idea has been successfully developed.

I'm "manually" resetting my 50G10 in regular basis from about 2 years without any problem, the image quality is still very good.

Without this fix this tv set would have left my living room long before ;-)

1 week later after installation...

I gotta say that that my PMCv1-equipped 46-G10 is way better than the 50-G20 when I bought it new.

Here's the issues I noticed (back in year 2010) and were apparent right out of the box with my G20...
- noticeable line bleed....... barely noticeable with my 46-G10)
- "pumping" blacks/brightness when scenes gets real dark....... none whatsoever with 46-G10
- "floating" blacks....... none with 46-G10
- "grainier picture when used as PC monitor with HDMI....... 46-G10 has almost no grain

The only thing the G20 has over the G10 is the capability to produce LCD-like light output in THX mode, with more headroom for light output adjustment. I have the living room 50-G20's contrast set to 68 and brightness to 58 to make this plasma shine during daytime.

The G10's light output in stock THX mode seems maxed out with no more room for adjustment, and it seems that G10 in THX mode is intended for night viewing only.

PZ80 is not very bright either, but enough for my darkish living room.

You have the G20 cranked up it will look more "grainy". Try lowering sharpness too, like 0. Make sure your changes are applied to ALL inputs, including the computer input.

Wow! I've been away from AVS for a while and just returned as I was thinking of replacing my 2009 TC-P50V10 due to the black level issue. Now I see this thread has been resurrected and that Dane has developed a solution! Of course, he's sold out right now. I voted for another batch on his website.

Dane - thanks for all the hard work and I look forward to another batch of PMCv1's so I can save a ton of money and get my beloved Panny plasma back!

Some feedback from a french dude !
My tv is a 42pz81fv so I wasn't sure on the compatibility but wanted to try the device anyway until it ran out.
My tests are not conclusive for the moment. I had some trouble installing the device because I turned my tv off with the power button and the leds didn't light up. I put the tv in stand by mode and it seemed to work but I had to turn the tv off (with the power button) then back on. All this trouble caused a little bit of stress and I forgot how bright the black exactly were so I can't tell for the moment if the device is working or if t's just a placebo effect.

I'll try the calibration tools from a disney bluray and it should be more conclusive because I used them last weeks to adjust my set before I got the PMCv1.

I got more time with the set and it definetely improved my black levels.
Thanks audiodane for the good work. You can add the 42pz81fv to your list.

This is part of the procedure, documented in the instruction sheet and reported here many times.

I wanted to echo this comment. I had given up on my G10, and then I just came across this project. I'm excited to hear what happens with the second round. Thank you for all of your work!

To be fair, it is not stated for the installation procedure but for the routine reset every 150h.
I'm just glad everything is working fine and my picture quality never been this great.

1. What if I decided one day that I want to unplug and move my 46in G10 (with PMCv1) to another corner of my room. Will this affect the functionality of PMCv1

2. If I leave the 46in G10 turned on in HDMI input without signal (cable boxed turned off for example), does PMCv1 still count the hours?

I think there is also some information probably lost in translation .. I have several overseas customers who have had a few differences of opinion as to what some of the instructions meant. I speak English, Bad English, and Engineering.. Unfortunately the latter is most common and is probably the worst language of them all!

PMCv1 doesn't care where you put your TV or if it's left on or left off... However, the PMCv1 only has access to restore blacks when the TV is turned on. Once the TV is on, the PMCv1 doesn't have access to the necessary information until the next time the TV is turned on. Leaving the TV on is no problem. If the TV crosses the 150hr mark while on, the NEXT time it gets turned off and back on, the PMCv1 will restore the blacks again..

Great photos Luis67, thank you! I'll add them to the website later (but not tonight-- too busy). So glad you're happy with the device.

Thanks Todd- It's "that time of year again," when I get swamped at work with deadlines over the holidays.. Here it is Tuesday night before Thanksgiving and I'm still at the office and probably will be until around 3-5am in the morning.. Another deadline will hit around Christmas.

I'm trying *SO* hard to get PMCv2 kicked off.. I might have to just go ahead and put up the preorder page so people aren't "left hanging." I was REALLY hoping to expedite the process and give everyone a nice holiday surprise, but work schedules have completely obliterated that chance, and I'm pretty bummed about it.

PMCv2 will be ever so slightly wider (0.75" instead of 0.6") to provide a little more durable protection during shipping... We've had at least three international units arrive in fairly beat up shape.. I will also be adding a couple lines of software that will utilize the second switch to turn off the LEDs, based on some of the user feedback that I've received about some people not liking them. Sorry, I can't easily make them "less bright," but I can "turn them off." I'm just hoping people don't think it's broken because there aren't any lights showing...

cheers,
..dane
