Hi - I appreciate the help
I followed the advice in the order provided:
Support - Support -Self Diagnosis - Picture Test disclosed no visible problem to me. I then went to Software Update as advised on screen. Running Update Now no new updates to be installed. Current version stated on screen to be 1280.
I went to link provided and downloaded to USB stick T-KTMDEUC. Whilst waiting for zipped file to expand review further advice. Checked both Support - Self Diagnosis and General - Start Setup and both greyed out and not available.
Plugged in USB but as uncertain about how to install contents of folder onto TV but given information on screen that software up to date decided to try switching off at the mains ahead of reset to factory settings before attempting software update.
Screen resumed normal image display after turning TV on and off at mains.
Thanks for the information. I'm not sure why TV refers to having been updated to 1280.5 rather than 1280. Also curious to know more about udating from USB but unwilling to experiment at this point in time.
Happy that screen image now normal!

UHD TV 6 SERIES 40' Model UE40MU6120K
O n all channels the aspect ratio seems to need adjusting. TV wirelessly connected to internet and accessing free view channels. A sharp edged vertical column on the far left hand side of the screen does not include the image. It is not a black column but appears to be related in some way to what is appearing in the image on screen but at a different resolution. I have attempted to adjust picture using remote without any success. Any help appreciated, thanks. Jeremy
