This is a 2011 vintage set (at least, that's the firmware date, I think we bought it in '13) and is fully digital, HD, 1024p, etc. etc. and works fine in the UK, worked fine in france for digital terrestrail TV last year. France changed their DTT standard in some way recently (I think they switched to MPEG4 instead of MPEG2 - but it's hard to find out!) and now the TV won't play ball.
Sharp support have trotted out an electronic shrug, basically saying it's a UK spec set and they can't vouch for it working in any other country, despite "what country are you in" being part of the basic setup. They say there's no firmware update for it. I think it's a cheap badge-engineerd set they knocked out as a cheap deal one Xmas, and never had any ongoing support after that. Pity - picture quality is fine from BluRay or Astra (UK) Freesat decoder.
Our other telly is a Sony of even older vintage, and it was utterly fine! All we had to do to "adapt" it to the change was tell it to re-tune all the digital chans, took five mins, and BING, french daytime soaps in full HD. OK, now I come to think of it, why do I even want this TV to pick up french telly.. Ah, tomorrow's Clermont match!
