I have a KDL-40WD653 (2016 model). It has an issue whereby after loading one of the BBC apps a few times (e.g. the iPlayer app), subsequent attempts to start the app results in a brief loading animation followed by a black screen, and then nothing else. I can exit out by pressing the HOME button, but I have to power off at the wall to get the BBC apps working again.

I have noticed a Sony issue announcement: https://www.sony.co.uk/support/en/content/cnt-hn/prd-tvhc/announcement-KDL-WD6/KDL-40WD653 - however it makes no mention of what issue the announcement relates to.

Does anyone know what specific issue the Sony announcement relates to, and is there an easier way to "reboot" the TV than powering off at the wall?

Thanks.
