I would like to thank Zoyd, TivoHD, LarryInRI and everyone else involved with this thread. I have been following it for quite awhile but just recently applied the fix, and I must say that I have really enjoyed the PQ of the set for the past 2 years but now the fix takes this TV to a new level. I have had my 59D8000 since May 2011 and loved the PQ coming from a 40A550 LCD. I bought an i1 display 2 and used the free HCFR software to perform a DIY calibration. I was so pleased with the way this set looked that I was not willing to chance updating the firmware to fix what I considered to be a minor annoyance when compared with the beautiful quality of the image. That said, over time I began to notice the fluctuations more and more. Especially when watching very dark content or movies in letterbox, the brightness “pops” became very apparent. Even to the point that family members, who had always commented on the quality of the picture, began to mention that the brightness “pops” occurring throughout the movie were distracting. Then in August I ended up giving away my very first 2006 Panasonic plasma to my sister in law going off to college so I was in the market for a new TV. I settled on the VT60 after reading numerous reviews and hearing about other people’s experiences with the set here on AVS (thanks again forum members!). This gave me the courage to go ahead and try the firmware update (I was still on 1018), I downloaded 1024.8 from the first post to a USB drive ensuring the folder was named properly and plugged it into the set. The difference was immediate; I put on the show Supernatural from the CW (one of our favorites with very dark material) which was one of the worst shows for fluctuations. There were none throughout an entire 1 hour episode, I was so happy I called my wife to come in the room and she couldn’t believe it. She said the pops always annoyed her, but she didn’t want to say anything about it since I had returned 2 TV’s prior to getting this one. We have watched numerous shows and movies (with letterbox) over the past 3 weeks and have yet to see a single pop. I have had my VT60 for almost a month and side by side it is apparent that the VT60 has deeper blacks, but the PQ on both sets is quite amazing and I think that with this fix applied the D8000 is at least in the same league as the VT60. I highly recommend that anyone with a D8000 perform this fix, if you haven’t already. You will be amazed at the difference in PQ, zoyd’s post #1594 in this thread details the performance of the much heralded F8500 compared to his D7000 and I can see why everyone is pleased with the image of that set because I believe my D8000 is probably very close to it now. I didn’t even have to input my calibrated settings after the firmware update, so there was really no hassle at all, thanks again.
