We've had a new T6 box for some months and it's worked perfectly, but today (for the past few hours), we've had sound, but no picture on any live tv channels or recorded programmes. We can see the guide and on-screen listings, but none of the programmes.
We have re-housed the cables, tried switching off completely, unplugging and restarting, but the problem persists.
We had an engineer visit yesterday for this issue. He told us that there is an issue with the v6 box communicating with some Samsung and Panasonic tv's (ours is a Panasonic) This requires a software update which is being worked on and should be applied soon.
