LOS starts blinking red and no internet

For 13 jan , 19:00 , The LOS light blinks red.

The internet was working perfectly before this. We have the new Hawai media converter . This was installed months back. 

The power and restart do no work.

Looks like table 1-15 : 4 : Issue with ONT signal. 

Is this a local issue or issue in Nieuwegein?

Who can fix this? I need the internet voucher to internet till it's fixed.
