Hi, after 4 years of faultless operation my hub 3 power light has suddenly changed to permanent red. It feels no warmer than it ever has but this is of some concern. I have tried several reboots by removing power completely and even left it for over an hour before restarting so that it was definitely cold. Although the power light goes green briefly during the startup sequence it now always finishes red. Wi-Fi and general internet access seems ok on the whole but I have noticed that streaming services now seem to stutter and break regularly.
Something is clearly wrong and the risk of overheating leading to potential fire could be a possibility according to the troubleshooting information.
Can someone please advise the steps I need to take to get this issue resolved asap?
