Screen flashing after battery replacement

Replaced battery and as soon as desktop appears the whole screen/ finder starts jumping about randomly. I can still use the mouse, click as usual. If i restart in safe mode this stops. Never seen it before. Wondering if it is something to do with graphics acceleration as i elive this is switched off in safe mode.

Hi

I use a MacBook Pro 2014 15inch and I bought it with this exact same problem

You need to unplug the display from the board and if that doesn’t work try unplugging the display from within it self which involves taking apart the display from the couch cover(black bit at the bottom of the screen)

If you need any help with it give me a shout and il help you step by step

Thanks:-)
