Hi KeithKay,
Welcome to Sony Community!
We're sorry to hear about the issue on your laptop. It sounds like this is already a hardware issue since you mentioned that the display fades in and out when you put pressure on the keyboard.
Try this step to confirm that it is really a hardware related issue. Turn off the unit and press the ASSIST button, replicate the issue. If it exist then you need to have the unit repaired. Please refer to this link for more details, https://esupport.sony.com/US/p/service.pl
