I've read about the FBr problem with last year's Panny. I've got a VT30 and would like to check my build date. I've looked all over and can't find specifics. I've seen some suggestions it's on the box - but not on mine. Then I've heard on the back of the TV, although I've also read some comments about having to peek between some slits. I can tell many, many of you know your build date. So can someone tell me specifically where to find it. THanks.
