Hi - My KS8000 is 30 months old. From the start is has been afflicted by difficulties connecting to a Samsung soundbar (K551) requiring a workaound each time (say 2 out of 10) that this happens. Now for the last 10 days the TV has randomly started to turn itself on, sometimes three times in a day. This is a signficant risk as it could result in the TV being left turned on for hours when no-one is in the house. Sometimes the switch on is to the TV Plus source (quite often to channnel 4000 (which I have never used) but sometimes to a local freeview channel. On other occastions the switch on is to a HDMI source... but the HDMI source (say my SkyQ box) is not powered on. I have checked that the Broadcast autotune feature is turned off (and also that the "turn on to check for auto tune changes" is not activated) . There are no timers set; I have turned off eco settings etc etc. I can only think this is as a result of a recent software upgrade. Any thoughts as I am about to consign this set to the junk yard. Its a pity - I love the picture; yes the sound connection is an issue but can be worked around; but the random switch on's are dangerous and cannot be tollerated.
