Buzzing from wall above ONT open reach box

[Josie3192]

Hoping someone can help or point me in the right direction! 

We had an open reach engineer out this morning to connect our Internet. Following this, there has been a loud buzzing coming from the wall above the ONT box. 

I've turned off the plugs and left to sit for approx. 30 minutes but the buzzing has continued. 

The box itself isn't covered and doesn't seem to be overheating. It was also plugged in prior to being connected with no buzzing or strange noises. 

Any help or advice would be appreciated!

Hi @Josie3192 

That is odd. Do you know if there is any sort of cabling in that area the engineer may have damaged?

Hi @jamesn123, I wouldn't have thought this was the case. The box had already been installed so there wasn't much he had to do inside. We're in a new build so seems this is the first issue to crop up! That being said after speaking with sky and then the builders, I was due to call open reach but the buzzing has stopped on its own last night. I still have absolutely no idea what it was but so far this morning it's staying lovely and quiet. Will have to keep an eye (or ear) on it for now.
