Hello I was in MRI and my watch was unresponsive. What is the problem?

Shaymaa - Responder

My button Ribbon on my Mainboard has come detached. It seams like there was some adhesive holding it on so i pressed it together. put it back together but the buttons wont turn the watch on. it is charged. I can’t tell if the Ribbon was soldered on or some adhesive used to make those connections. Any help would be appreciated.
