Samsung A53 oled display shows random pixels and crashes then restarts

So for last few days i have problem with this stuff. I saw one person having same problem as me and answer he got is that maybe display is damaged, which was interesting for me since i tried everything. Only thing i need is someone to tell me could that be reason why my cpu/ processor is overheating and if yes does changing display really help.

If you have some kind of link where i can buy new display for not too much money please share (if possible amazon link)

Thank you.
