Here is the story. Bought a ZT60 which was made in July 2013. Had a perfect picture but fans were making too much noise. Had it replaced with the the other ZT60 made in October 2013. Fans are quite now but the picture on a new unit is visible darker, on every picture setting.
In general it looks like brightness on the TV made in October in every picture mode is a level darker than on the TV made in July. For example: brightness on the THX Cinema mode on the new unit looks like EBU default on an old one. TXH Bright Room on the new one looks like THX Cinema on the old and THX Bright room setting on the new one it's just not as bright when there is sun in the room.
I'm comparing the same movies and it's not just my opinion, my wife noticed the same difference in the picture brightness.
Did i get a defective plasma? Is TV going to get darker with age? Should i replace the unit. Kind of lost here.
Appreciate any input.
