Hi Ziggy. Firmware issue on your main AV board my friend. I have heard of this with UMCs before.
You could try a factory reset. If that doesn't work, you could try updating the firmware with a usb flash drive - you would have to find the firmware for your particular model from the manufacturer's website (assuming they have one).
If that doesn't work:
Obviously, if it is under warranty contact the seller or the manufacturer and they should sort it out for you.
If it is out of warranty then you could try replacing your AV board. Spare parts from TVs damaged in transit or used parts are often listed on eBay and other specialist TV parts websites.
You would have to open the back - remember to UNPLUG IT FIRST - and you're looking for the big circuit board that has all the video inputs in. Find the part number on it and search it on eBay or a site like www.flattvparts.co.uk - replace the board and (assuming they sent you a working board) that should solve your issue.
