It's not actually an HD TV - but the deal on a new box was cheaper than getting someone out to look at my dead old box.
It's a fairly old JVC AV28-plus a bit more model.
I've set up the HD box fine but any text on the screen is blurry.
e.g. the scrolling news on BBC.
The picture looks ok to me.
A quick google has mystified me, something to do with pixels and hdmi and 720p 
The tv does not have an HDMI socket (or at least I'm pretty sure it doesn't) so the Sky box is connected with a Scart lead, as before.
Before, when you turned on the tv, the text would be blurry like this but when you pressed Sky on the remote it 'deblurred' /sharpened up, that doesn't happen now.
Any thoughts/ideas please?
