XR-65X90J Disappearing Sound on Numerous HDMI ports

[Shwing]

Hi.

I mainly use my tv for PS5 (HDMI 4) & PC (HDMI 3), and have always had the occasional disappearance of sound on the PS5 HDMI 4 channel - where only a restart will solve.

Thing is it's started to happen even more regularly, and now is also doing it with my PC on HDMI 3.

Any ideas / solutions?

I really have lost so much faith in Sony products, as the quality seems a shadow of it's former self (yet they still charge a premium).

Any help much appreciated, as I'm not going to restart set every time - I shouldn't have to.

Ta!

Anyone?

Full factory reset.

I'll try that. 

Is this a common issue with this set do you know?

I’ve not come across that one, but issues with Sony TVs are all to frequent, and Sony will always ask you to do a factory reset before anything else; so I’m saving you time even if it doesn’t fix anything, but especially if it does 😛

Well that was good. 

A few hours ago got around to doing a full factory reset on TV only for there to be no sound coming from PS5 Pro on HDMI 4 the second the reset had finished. 

I'm now resetting TV couple of times every day to get sound back on silent HDMI channels.

I assume I'm going to have to log a service call?
