Oppo F5 Phone display gone and is not switching on

My phone was working very well with no interruptions or delay until one day it got switched off, and even when charged back, it didn’t show any response and it looks completely dead now with no signal or a single light and when I took it to Mobile repair shop, he said phones display is gone, and instead of changing it, you may get a new one.

i I would like to know if there’s a way to work it out?
