Power adapter failure and screen issue
Last week my HTC One M8 stopped charging correctly. When connected to the charger the orange indicator light would come on for around ten seconds. It would then go off and a battery with a lightning symbol inside would come on the screen. The screen would then go off and the cycle would repeat itself over and over.
It sounded as if there was a loose cable inside the phone so following the ifixit tutorial I opened up the phone and checked the cables. The same issue occurs when the phone is plugged in to the charger. However now the screen only shows a static background. Have I potentially broken the screen by providing a static shock to the motherboard or ribbon cables?
Any information regarding the initial problem of the static screen is greatly appreciated.
