• Hello, after i have made the update to v6.1288 on my Sony 55XH9077 i have discovered that are some problems :

1. The tv doesn't power on sometimes, i push the power button from my remote, the logo white led it is on but on the tv i have black screen, i have to push again the power button, sometimes TV turn on ok with the home screen , sometimes i see the Android logo and the TV start with the boot process. 

2. On the previous firmware version the optical sound output worked ok, now after i open my harman kardon amplifier i didn't have sound, i have to go on the TV to speakers settings and to select the "audio system" option.

3.  when i use tv cable application (oem), when i change the programs i see the blue circle arow and took a while until the program change, on the previous firmware version, the programs selection was mad instantly.
