Alarm clock doesn´t work, still the display blinks

Alarm clock doesn´t work, still the display blinks
I lived 6 months abroad, and after I returned home, I realised that I had forgotten to unplug my alarm clock. I found the display working normally, but the digital digit segments were all blinking. (With digit segments I mean the digital 8 which is used to represent all other digits in digital displays.)
