I currently have a 24inch widescreen Sony (I think its a KV-24LS35). The image seems good to me, but the speakers have started sounding poor with a nasty buzzing during certain bassy sounds (like low pitch voice). I would like to upgrade to a 28inch or 32inch. However I want 5.1 sound WITHOUT having to get an amp, and I would like the noise reduction feature of my Sony (seems to reduce volume for adverts). I really fancy something like the Toshiba 'picture frame', with its external speakers - but they are a bit out of my price range. Any suggestions welcome, but what are decent, cheap, 5.1 tv's?
