Hey, everyone.
So I figured I would post on this place as I'm essentially lost for what to do at the moment. I'll try and keep this short.
Basically, my PS4 has been displaying occasional graphical issues for a few months, but only sporadically, never as bad as it is currently. I noticed it got particularly bad recently playing Hellblade and Horizon: Zero Dawn. I can't really find the right way to describe what it looks like, so check out the embedded videos I took whilst playing HZD to see what I mean.
This usually occurs after about 30 minutes of play and once it starts it get worse rather quickly. Nothing is really playable like this. It occurs across different games, so I know the issue is not with the software. These issues never appear whilst I am using apps like YouTube or Netflix, or when I'm just on the dashboard. I've tried switching HDMI cables and using different jacks, but no difference has been made.
I did a bit of research online and figured it might be an overheating issue, so in brief, I did open the thing up (I was a month past my warranty when it got this bad, go figure) and I replaced the thermal paste with newer stuff, reassembled it all and now the console still works as it did before...but no change at all with the graphical issues.
I get the feeling I might have to send it somewhere for proper repair, even though I don't actually know what's causing it other than possibly a faulty APU / GPU. If that's the case, then I'm presuming sending it to Sony is the only option for repair unless I just save up for another console or something (which I can't really afford anyway.)
Any help or advice that anyone could provide regarding this issue would be super appreciated. Thank you!
