Vertical & horizontal lines on screen

before anyone says anything - this was not dropped. It happened when using Procreate but there was no heavy leaning however this isn’t the original iPad screen, it had to be replaced previously however I’ve had no problems for a year.

can someone suggest a fix? Or do I need the screen replaced yet again?

Nobody from my family will be going anywhere near an apple shop due to covid 19 and how risky it is for us
