Is it my eyes or it is possible that a new Panasonic V2558" set has lost major black levels effecting the contrast within a couple hundred hours? I do not have a way to measure this but my eyes tell me yes, how can this happen?

Panasonic has a known issue with rising black levels. It's not as bad on 2010 sets as the 2009 from what I've read....but it does happen.

Yes, but in 200 hours should it be visible? This is concerning.

I think it has to be at least 1500 hours for the first rise to happen.

My eyes don't lie, this picture looks like a washed out several year old plasma. When I purchased it was awesome, now I see why people are so concerned.

Get better settings on your tv. Adjust to changes in your vision. It's also possible you have a defective tv. Strangely I think of my tv looks great some days and not quite right other days. Just the second guessing and looking for flaws can drive you crazy.

Yes, this forum can make you see things. I might trade or the XBR52909, not as good but blacks stay black. Remember seeing a large Panasonic Plasma at Best Buys for a steal about two years ago and wondering why the picture was washed up, now I know the blacks did rise washing out the picture.

On my kuro, I failed to see what all the buzz was about (I recognized that it was better) in the sense of blowing everything else out of the water until I enabled ISF modes and tweaked them for optimal PQ. I would expect your set is the same way. Also, my recollection is that Panasonics new sets ship by default in "energy save" mode that uses minimum output and looks like crap. Panasonics do have rising black level and it will brighten notable by the time it stops, but I'm inclined to think that at 200hrs it is more bad settings on the set than anything else.

I had a Pioneer Elite, the last 50" model made, the best picture ever accept I was bothered by motion trails and could not watch the set.
