I have a KD-48A9, which is running the latest firmware 6.6152. I find that sometimes after watching a recording made on my Panasonic DMR-BWT800, when I put the Panasonic into standby and then turn off the TV a few seconds later it will turn on again.
I turn it off again and a few seconds later it will turn on.The two external devices connected are the Panasonic recorder mentioned and a Sky+HD box.
I find that if I long press the TV power button and then do a restart, wait for it to come back on and turn off again then it will stay off. This makes me feel it is not a connected device, but rather a software bug on the TV. Has anyone else experienced this?
