I own a 32plf7675h/12.
As far as I know the software is up-to-date. I cannot check any software release due to the rebooting issue.

Once the TV is started I see the last used channel for about 3 seconds. The TV does not respond on the remote. The red LED blinks during startup.
Then the screen goes black and the side lights start a "light show".
Startup without the cable connection did not help.
The TV become unusable.

Help / tips / tricks are very much wanted / appreciated.
