Two things I don't understand....
Unless your telly has lead shielding I don't see how it can be 100Kg! My Sony WEGA 32" weighs about 35-40Kg. It definitely didn't weigh 100Kg because it only took two of us to load it onto the stand. If it had been 100Kg, that'd have been 50Kg each and I couldn't lift that that far, I'm sure. Why do you think it's 100Kg?
Secondly, what's all this about TFTs not doing SD signals well? I was running my A1200 on my Sony 40W3000 (40" TFT) and not only was the picture signal fantastically clear (perhaps a little too clear as it showed up every pixel) but also it scandoubled the A1200's interlaced output so the picture was solid even in PAL High-Res laced. Very handy!
