• 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.

Have you tried doing a factory reset after you updated your firmware?

I had issues with slow menus after I updated so I did a factory reset. Things are working a bit snappier since.

I also use the optical output and haven't had any issues with it since the firmware update.

However, I now have issues with micro stuttering when watching bluray's. I've watched two bluray's (one 4k and the other 1080p) since my update and both have micro stuttering. My bluray player is connect to HDMI4.

I honestly wish I could just roll back the firmware. I've just got rid of a Hisense TV that had issues only to now have a Sony with issues. I can't even watch a movie without this annoying stutter now. Fed up with it all tbh.

I'm using v6.1288 on a 55XH9005.

I have a lot of applications installed and i'm so happy to do factory reset, but maybe i will try this because now the tv power on action it is very frustrating.
