Thanks for the advice of members.I finally have the T.V I selected.
The one we took back,had no insides in the remote at all-no printed circit
boards or wires,so the alfoil fix it would not have worked.
Had to wait a bit for the shop to swap it over.
Interesting,I see the handset has a passed sticker on it,the other did not.
Certainly one good suggestion here by a IIS member-open the box in the shop to see if bits are in there,and open battery bay-if the item has one.
Not real fussed the image quality of these new flat screen TVs I think the old ones had better contrast,and image.But that's 'progress'.
I have had lots of different tools and electrical goods over the years,It appears to me most items made between 1920 and mid 1990's,seem to be of a higher standard in quality.
The gauge of thickness of metal.plastics and material always had a better feel,like it might last!
In the good old days many items used to made in Japan,always a good sign to my mind.The U.S also used to have too much pride to make and sell lower quality goods,although I feel their standards a lowering.
English and Australian tools and electrical gear also used to be of a high standard,but all the good names have been bought out and made in various parts of Asia.
Some of the items I can think of that are still well made are Canon L lenses and Alvey fishing reels,I buried a Alvey reel in the sand at Fraser once,found it Sixteen years later with my metal detector,and still worked fine (I bought it second hand at a garage sale-and planned this test as a bit of a camp laugh,but was amazed to find it and still be useable

)
Will have to check electrical purchases before leaving shop a bit better fron now on
