As you'd expect, the blacks are shot accordingly. As much as I'd love to revert the set to new, I'm a little hesitant to do so given the age and heavy usage of the panel.

Perhaps I'd be better off going the homebrew route and editing the EEPROM to something like 500 hours of usage (so after the first black rise step) rather than going all the way to 0?
The PMCv2 has an "undo" switch that, well, undoes the clear, in case you are nervous about anything. That said, there are folks with well over 10k out there using the PCMv1/v2 just fine.. If you want to force it to 500hrs though, yes, you'll need to use mironto's DIY method..

cheers,

7210 hours isn't that much. I wouldn't hesitate to reset the tv back to 0. I'm getting ready to reset my V10. Tried to find out the number of hours today via the service menu but the instructions for checking the hours in the service menu didn't work on my V10. Even if mine is over 10,000 I'll reset it back to 0.

Just reset my 54" V10 and all I can say, the result were dramatic. My set had over 10,300 hours on it so the rise was significant. I've had my PMCv2 since October, 2014 but never got around to installing it. Wish I hadn't waited. Even my could not believe how much better the picture was improved by the PMCv2. Wish I could upload the before and after photos, but can't get it to work tonight. I try later when not so tired.

Thanks to everyone who contributed to the thread and the fix!
