Hi
When this happens to me I can usually fix it by cleaning the connectors (both screen and board)with some isopropyl alcohol and cotton buds/QTips as it will remove invisible dirt that our human eyes can’t see
If it doesn’t work I would follow through with your conversation with support but I wouldn’t expect to hear back from them until after the weekend as they might be home right now
Hopefully this helps
Any questions please ask
Thanks:-)
