55A95L (UK) total sound loss

[ChewyUK]

I purchased a 55A95L in December 2024, I also purchased a TA-AN1000 receiver.

the tv is connected to the receiver via hdmi 3 and is using eARC.  

Sky Q is connected to the tv (HDMI 4) 

pass through is turned on

when it works the sound is very good, although I do experience slight pulsing from the speakers when there is no signal or when using apps (which shouldn't be happening on such an expensive amp)

i now experience total sound loss on any source (Sky or apps).  The only way to restore sound is to restart the TV, I've tried to restart the receiver and the Sky Q and have narrowed it down to the TV as the source of the problem. 

does anyone have a more permanent solution to this fault?

As a side note, I must say I'm really disappointed with Sony, against my instinct I chose Sony again after owning an XD9305 which was replaced 3 times for being very unreliable.

As Oscar Wilde said of second marriages, the triumph of hope over experience.

I think your more permanent solution may be badged LG or Samsung, once you have returned this Sony set for a refund 😢

Have you tried to test the TV without the devices that is connected to it? Or tried to factory reset it?

Have you tried disconnecting skyq if it stops the issue? Sky devices are known for causing issue with hdmi CEC protocol. If it works you may want to connect it with an hdmi cecless cable later on.

Update. The issue was with the Sony AN-TA1000 receiver in the end, I had convinced my self it was the TV.   I ended up factory resetting and re-calibrating the reciever, I also took a gamble and loaded the Bravia 9 firmware 112.628.050.1 on the A95L, the firmware took, not only is everything working now, I think the HDMI control works more consistently when turning off devices from one remote (as well as a slight reduction in the pulsating from the AV speakers). I suspect the receiver may have crashed, although it appeared to be working, another tell tale is that it would not connect to the internet by wifi or ethernet. a reset did the job, something to keep an eye on.
