Here is another case of late BL rise, from Italy :
50G10, bought in november 2009, started with great black level of about 0.03 cd/m2 (about 0.009 FLT), now is near an awful 0.115 cd/m2 (about 0.034 FLT).
Useless to say, this is not what i paid for and i paid a lot.
The PQ is affected as much as numbers could suggest, it was clear to me that something of serious happened long before any instrumental test result.
Now i have an ANSI contrast that is less then 1000
Sadly, the last and the worst black level rise took place between 5000 and 5500 hours of use, just few days after warranty end time !
Looking for a solution on the web soon led me to Panasonic official answer about this matter, that in facts leaves customers in the mud.
What a delusion, i spent the last twenty years buying and suggesting Panasonic devices and now this "kind" of treatment
I guess i will change my habits.
And If, as i fear, there is no feasible solution for DIYers on the way, i will have to sell off the TV set at bargain price
After only two years, sure not a great deal.
Hi to all,
