Hello!

What could be the problem when system crash with green screen when playing Spider Man 2 or other PS5 high demand games?

Powersupply has been swapt for test.

Console is dust free.

Cooling forks fine.

Liquid metal has been repaired.

Hdmi port and cable are good.

Could it be Hdmi encoder or smth.

Thanks!
