Going round in circles, help please. Red light on solid on ONT.

[LAS2917]

My power was off for a short period over the weekend. Since then the red 'alarm' light on the openreach ONT box has been solid red. Internet seems to be working ok but I havent been on laptop or phone much to test it consistently as its been Easter and had family over. The TV wouldnt work for a while but seems to be working ok now. I have googled this and it seems to indicate that it could be a fibre line fault and I need to report to sky who then need to report it to Openreach. I have tried to find a way to contact sky without phoning them (previous attempts to phone sky during working hours have been horrible, I am busy and can't afford to sit on hold all day long). Can anyone help direct me to a place where I can report this to them via a virtual form? Just had the most frustrating chat with virtual assistant and got nowhere, so trying this community in hope someone can help!

@LAS2917   First thing to check is this link to see if there are any outages in your area:

https://www.sky.com/servicechecker

If there isn't try running the line test here:

https://www.sky.com/help/articles/broadband-diagnostic-start

You can also run the test via the MySky app on a mobile data connection.

After this has finished and if it reports back all is good click on broadband to run an updated test. If you get amber or red please follow the on screen instructions.

@LAS2917 If you can take a picture off the ONT box model that you have and post that up, if an older ONT some had a battery back up combined unit, use the camera icon to attach the picture. Have you tried switching off the ONT to see if the alarm light clears also?
