KD85XH80 stuttering even after reset and software up to date

[Theneo]

Hi,

My Sony bravia KD85XH80 suddenly seems to have developed stuttering across all applications. I am using YouTube, prime, Netflix everywhere this stuttering is so bad it is impossible to watch the TV.

I already have tried to restart, factory reset and also tried to update the firmware through USB. The tv shows the message software is up to date, though I can see my kernel patch is 4.9 and date put is 1 Jul .

Hey @Theneo, I believe you need to check the PKG number on the Help menu. The latest version should be 6.5076. Also try to connect the TV to different internet source other than the WiFi network and check if it's still stuttering or not
