Sony TV fault

[SAH]

I've seen a 28" Sony TV for sale in a Sony shop, it's advertised as refurbished, when I asked the assistant what was wrong with it he said that it had been returned to Sony with a faulty teletext board. Obviously it's been repaired now, but if I'm happy with the picture is it ok to buy this TV or is a faulty teletext board a fault that's likely to re-occur??

Ensure you get a warranty (without paying extra for it), and you should be ok.

Yeah that's a good idea Chapel, thanks :-)
