What should I do?

Many customers are giving feedback with a similar issue. "antenna power is off and unable to turn on.

Through remote control can turn on but it will go off when pressing the exit menu.  Need to pay attention  


Answer: Engineer guesses that the problem is from the rf antenna protect IC has a problem,  (amperage limited is smaller, it is better to change bigger amperage ic).  


This protects IC function is protect the TV Board if the antenna has a problem (for example shorted) AN_SY6280 from http://www.silergy.com/
