how to repair Mxq 4k android tv box

Hi Everyone,
I was given this Android TV Box to repair it and the complaint was that it won’t turn on.
As an additional symptom, I was told that several times in the past, the cable had to be wiggled close to the power jack for the box to turn on so I knew that the fault was either in the power jack on the Android box or in the power supply cable.
thankyou.
