I have an S95 OLED tv and is a great TV but I'm facing some issues. I have the TV connected via E-ARC to a Denon AVR-X2700H that is connected  to a 4K TV box from a TV supplier and other sources. Sometimes whe I turn on the 4K TV box  the TV starts to work but there is no picture in the TV just sound. After a while the picture comes and works normally. This doesn't happen daily but some times happens and I wonder if is a problem with the TV or is a SW issue.
