I got a PS3 slim 120 Gb to repair. First it wouldn't turn on so i changed the Power Supply Unit and it changed something. Now the PS3 turns on, shows a quick yellow light after the green one, beeps three times and goes to blinking red. It seems to be a classic YLOD but 1 out of 5 five times, it turns on and keeps going but the screen remains black.
I can put in and eject a blu-ray and i hear the PS3 reading it but that's it. I changed the thermal paste and put a brand new artic silver but it's still the same. It was 3,5g for the two chips so maybe it's not enough... What do you think?
