Sony 5 Fat disc drive. The device is working fine, but when it's under load, it suddenly turns off. I have changed the thermal paste twice, and it didn't help. For your information, if I play Shahid, Netflix, or PS4 games, it doesn't turn off at all. I don't know what the problem is. For sale for the best offer. The console is in good condition, no cracks, and comes with its cables only. For sale for the best offer or a suitable trade.
