Dear Support

I have some Problems with the 42" 7656

I have installed the newest Firmware.
I have testet a Hardware Reset but the Problems are still on

- TV shut down without my Action , this comes 1-2 Times on a Day
- sporadic outages tone , comes every 30-90 Minutes , the failure is 1-2 Seconds , after this the sound is OK

No good, many Peoples have the same Problems.
