Yes, you can - and we're well aware of them (we don't operate in a bubble!)
All I can reiterate is that we had two samples of the KDL46W4500 in, and neither had clouding (obviously, or we wouldn't have raved about the set!).
We're obviously concerned that some buyers are having problems with this set, and have asked Sony - as mentioned above - for an explanation.
Those of you who've been on this Forums a year or so will remember there was a similar issue with some Panasonic LCDs last year/early this year - in that instance, it was a faulty batch that was to blame, and the issue died down once replacement TVs were in the market.
Again, we'll update you with any feedback from Sony - who are notoriously difficult to get hold of.
