I have the 46PFL8606 smart-tv.
While watching tv via the UPC tuner, which is connected via HDMI, the display turns black every now and then. It is also happening when i am watching my mediacenter (connected via another HDMI kabel).
I'm waiting for a new firmware update, but this is still not happening.
What can i do kill this anoying problem?
The current firmware is, 2012-11-27

Please HELP
