I have a 40pfl7605h/12 for a few months and there are 2 things i've noticed.
When I power of my TV (with remote control) there is an about 20% change that the ambilight remains lid. It is always in the color that it had before turning the tv of (it doesn't turn white or so).
I have to turn the tv on and off again to turn the ambilight of.
Often the screen " hangs" or "lags" for about a second and the ambilight goes off.
I am watching tv through DVB-C from Ziggo (The Netherlands) using a Ziggo CI+ module.
Anyone familiar with these problems, or does someone have any solutions?
I have updated the firmware a few weeks back.
