Is the PS4 a sign of itself if something s.der hardware is broken. So is it still at all if, for example, the GPU, the CPU, the RAM or something else would be broken? Or is there any other sign of something if something is broken on the hardware which does not affect the ventilation?

Theoretically, in my opinion, the lamp gives a light signal (power LED)

e.g. Blue Light of Dead
