Its also funny to me people with g15 claiming they had deep inky blacks in a all dark room. I have seen that TV and with the correct bias lighting you can create that inky affect but in a all dark room with black bars it will always be charcoal grey... can anyone with a v10 with over 500 hours measure there blacks and let me know what they are reading... i would love to see what everyone's MLL is currently..
I have a V10 like yours. July Mfg date and now approx. 1300 hours.
I do employ bias lighting. Up until early to mid-December, I had seen no change in black levels. Sometime prior to Christmas, there was a definite rise. My guess is this happened just past the 1,000 hour mark. The rise is great enough that the bars surrounding letterbox or 4:3 content always look gray, somewhere between charcoal (dark) and a medium shade. If the bars had just moved to dark gray, I may not have noticed the change at all. However, the change is drastic enough that it can be seen not just in a darkened room or with bias lighting, but with other lighting or dayight as well.
I have had two good conversations with Panasonic and feel that they are attempting to find a solution. I specifically asked the second CSR that if a fix was not forthcoming, could I expect Panasonic to replace the set and he said "Yes" and that he would notate it in my case #.
I would advise anyone suspicious of this to open a case with Panasonic while your set is still in warranty. Most warranties will support your recourse, if necessary, even after the expiration, as long as the problem was reported prior to that point.
So at present, I am being patient and reasonable. I notice from your postings that you also seem to act in that manner.
With luck, we will see a resolution at some point in the coming moths.
