Btw "auto start" is not the same setting as "instant on" -
Thank you guys - deactivating "samsung instant on" worked immediately (after switching off / on TV). I found it in - menu - system - general (scroll down to find) and there it is.....
I have the 9000 w the exact same problem and timing. All apps work but for amazon and netflix. Firmware up to date. Internet wifi work in the correct speed. iPad and Xbox still run netflix just fine.....
