Steve, Rob: I'd assumed that since Rob said the problem started 'a few' weeks ago, it was more likely to be a reception issue.
It's now 8 weeks since the second step and 10 since the BBC multiplex changed modes. If the problem started that long ago then yes, it could be a TV that does not support 8K mode - Mux 1/BBC A, 2/D3&4, B/BBC B/HD and D/ArqB have all switched into the 8K mode but Mux A/SDN and C/ArqA have not yet done so.

Mike Dimmick: Sorry to be picky, but BBCB uses 32k, not 8k...

I'm sending it back for a replacement. Thanks for the comments everyone - much appreciated.
Steve - yes, endless factory resets and "empty" scans etc! Got it mid May and it "failed" near the end of May so the mode changes etc shouldn't be related. Tried the attenuator to no avail. Replacement should be with me soon....

Replaced my Panasonic Freeview tv with a new Panny Freeview HD set today. SD quality has always been 10 and still is but the 4 HD channels only have quality of 2 . Although there is no picture breakup this still seems too low . Reduced power ?

NOTE: D3&4 and HD use transitional S1 antenna until 27 June 2012.
Nigel - Brian's note, above, may relate?
Also C21 is at the extreme of the aerial respnse range.

nigel: "If" you are referring to HD reception from Sandy, (on Ch21) I carried out a check on my Panasonic HD set a few minutes ago and have full strength indications on both signal and quality, my location being just outside of Stamford using a gutter mounted amplified log aerial.

Follow up to my earlier posts: returned the freeview device and got replacement. Scanned and picked up everything perfectly and immediately so the fault was with the box after all!
