my ps4 is suffering from the pulsing blod. i can get it to boot up if i keep trying but it acts like it’s overheating and freezes up and when it does the pulsing blod, my tv knows it’s connected to hdmi 2 and renames the input accordingly. what could the issue be? apu, ram, the hdmi circuit, power supply? i hope it’s fixable

One of the first things to try with a BLOD is swapping the hard drive. Or at the very least, removing it to see if you can get into safe mode with it absent. And since this could also explain freezing, I would start there.
