Hi, I have a CECH04 PS3 fat model which has a red light problem. This light usually indicates an overheating problem. I changed the top layer thermal paste which was pretty dry but it didn’t help.
When I turn on the console, it gives three beeps, red light (stand by) light goes to green and fan starts to spin for a second. Then it shows a yellow light for half a second and then the red light starts to blink indefinitely.
I know a PS3 can start without HDD and disc drive so these cannot be the reason. PSU failure usually won’t show any light or blinks yellow light
What other causes are there for this red light problem? Could the problem be in processors or capacitors? My guess goes to worn out lower thermal paste under the IHS (integrated heat spreader).
