After purchase my LG smart tv was able to pick up DTT (digital Terrestial Transmitters in the local area. These channels failed to work after some time and it was assumed that they were switched off due to the never ending wait for South Africa to migrate fully to digital.
However tuning my sons Hi Sense tv the said channels were found and indeed are operational as digital HD channels
Returning to my LG tv i changed the location to digital , retuned and lo and behold the digital channels appeared on a multiplex on uhf channel 49 (8mhz) however within a few minutes they disappeared never to be seen again isn spite of much time and many alternative settings.
I have tried changing location, adding channel 49 UHF manually which shows full signal strength and quality, but gives no digital programmes found.
I have had to revert to the 4 terrestial channels to get any tv operation at all.
I believe that my set has been crippled by LG. I am highly upset considering the cost of a uhd TV thats not capable of performing ito its original specification or at its best.
Any advice on how to obtain a working system ( frimware has been updated ) or the legal route to go to resolve this issue would be welcome.
NB as a retired broadcast technologist i do have some knowledge of the industry so would welcome any technical perspectives if i have missed something
thanks Mikei
