Thanks for response- at least somone read my post.

Channels are normal broadcast channels received on a normal Aerial. I all other respects tv is fine on iptv etc.

I have found out that my firmware version is not used anywhere else and is an upgrade on the uk and other PAL reception areas. All other firmware upgrades are documented on LG support site but not this one.

Thanks Again for interest.

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
