In early December I bought a KD49X8305CBU TV which initially worked fine after the initial set-up.

After I'd had the TV for a couple of weeks, I switched it on for the first time after it had been switched off overnight and none of the HDMI inputs or the terrestrial TV antenna input were working properly.

I could get sound, but no picture from my Sky box, PS4, blu-ray player, and the terrestrial TV aerial.

I carried out a factory re-set which seemed to cure the problem, but a few weeks later it happened again.  Once again, a re-set cured the problem but since then it's been happening regularly every 7 days or so.  Since I've owned the TV I've had to carry out 5 or 6 re-sets to get the inputs working every few days.

It always happens when I switch the TV on for the first time after it's been off overnight.

I carried out an on-line update which I hoped would cure the problem, but it hasn't made any difference.

Anyone else had a similar problem.?

Ray.
