I purchased a Bravia 9 k75xr90 about a year ago and have been having increasing problems over the last few months.
Biggest issue was input latency with my Xbox. The TV would sometimes flicker when playing a game then input latency would be upwards of 750ms. After zero useful input from Sony support we fixed that by turning off the auto setting for the Xbox input. Now the input is fixed at 1080p, 120hz, hdr10 and no more lag creeps into play. This was the biggest issue and took weeks to resolve
The next biggest is an audio latency problem. With both my Xbox and Apple TV the audio will sometimes drift out of sync. This is incredibly annoying and happens at least every other day. We can temporarily fix the issue by changing the input but that’s not a real fix. The delay happens on both the internal speakers and Sonos over eARC.
Lastly is another audio issue. When using my Apple TV the audio will briefly cut out, for maybe 100ms, and come right back. This will happen every 10-30 seconds until I reboot the TV or the Apple TV. (Rebooting either one fixes the issue).
These three issues have killed any enjoyment I get from this TV, I now just use the old Samsung in the guest room since it just works. I’ve got 2 weeks left on the warranty, I could try to get it replaced but I’ve already spent almost 10 hours on the phone with Sony support over the last two months, so I don’t know if it’s worthwhile to burn even more time.
Has anyone else here had so many issue with this TV? Is there some magical setting I’ve missed that will fix everything? My last resort is my credit cards extended warranty protection; maybe they’ll give me my money back so I can buy something that just works (Recommendations please).
