hiundai i20 2012 radio doesn't turn on

Hello everyone. This is a short video diagnosing the issues of a hiundai i20 which doesn't power on. check fuse from dash first and if that's good remove the trim around the radio (it's holding on clips only, just pull out around) and then the radio ( 4 screws) if there is power on the wires that means there is a issue with the radio unit itself.
