Sony Bravia KDL-46W5500 46in LCD TV Review

i'm in the hunt for a new tv and this sounds ideal, the only dilema i have is am i throwing good money away on "dated" technology, should i hold off and purchase a LED tv (maybe the Samsung 7020), i wouldnt want to buy this and then several months later feel as if i there are far better (LED) tvs out there, any thoughts?

I purchased the Sony KDL40W55000 one week ago. It was intalled and set up by the supplier engineer. I have two problems. I was told that I could connect a Card Reader to the USB Port to view my photos from my SD Card. No success.
But my main problem is as follows. At initial switch on of the T.V, after the normal 9 seconds warm up delay, a loud screech sound comes from the T.V.
The company changed the T.V but the problem continues. My set up comrprises a Sky Plus Box and a Recorder/Player. The engineer has no solution. Any ideas?

I've had the 40W5500 for 3 weeks... can barely notice any bleed unless I look at the very top left in a dark room with a black picture. You wouldn't notice unless you knew what you were looking for.

What I would like to know which I've found the AVForums with all their so-called experts have been unable to furnish us amateurs with, are what settings we should go with. Anyone? I think I may have a good set up but...

I read a loads of reviews about the W5500 model and I decided to buy it. But now I'm afraid of buying it just because of that slightly noticeable blacklight problem... Should I forget that problem & buy it?
