Unfortunately JL wouldn't help as I was past the day exchange period. They said that the defect would be covered under the manufacturer's warranty, and insisted that they connect me to Samsung.

I explained that I'd already contacted Samsung last week and they'd been unable to help. Nevertheless, JL spoke to them and then handed me over. At first Samsung said that this was not a defect and they would not exchange the TV. They said that I had to connect a USB drive which could then be used by the apps if necessary. What they were suggesting was at best a workaround, so I insisted on speaking to a supervisor re-reading the earlier post in this thread it looks like the USB solution doesn't work anyway.

The supervisor gave me a whole different story and was much more honest. She said that this is a known issue which has appeared randomly across the whole current TV range. She admitted that the USB drive suggestion was a temporary workaround until they could resolve the issue permanently. They had no timescale as they didn't know what was causing it. She said that she would contact me within three days with an update.

Currently I'm stuck between a rock and a hard place - JL won't help, but Samsung also won't exchange the TV as they're working on a solution which is seemingly open-ended. I must say I'm disappointed with JL and wonder what the value is of their 5-year guarantee if they're just going to fob you off to the manufacturer.
