So, you want to learn how to fix the PS3 blinking red light? I once had the red light of death and the YLOD on two separate consoles! I was so mad and frustrated at Sony because of the amount of money they wanted to charge me to fix my console, and I did not want to have to wait for 6 weeks for them to fix it and return it to me. That is when I got the idea that I might be able to fix it myself, so I started researching my problem on the web. I found out that there are a few reasons that the blinking red light happens on the PS3, and then I found out how to fix it.
The most common cause of the blinking red light on the PS3 is due to overheating of the motherboard. I only know this after doing extensive research when I was trying to fix my Playstation. Plus, when I called Sony they told me that I needed to let it cool off to room temperature for 4-5 hours before trying to turn it back on.
Another cause of the blinking red light on the Playstation is overheating of the hard drive. This is something that is an easier fix than fixing the motherboard (although neither repair is hard to do). By taking the hard disk out of the Playstation and putting it back in, you may be able to make the blinking light stop so that you can get back to your game.
Something else that you may need to check in order to repair your Playstation is wires that may be loose. Check to see if there are any loose wires. If not, restart your console. The next thing you might try is unplugging all of the wires except for the power cord and plugging them back in. If this does not do the trick then you are going to need to take other measures.
Sometimes what happens what happens is the GPU or the CPU come unattached inside the PS3. This is the main cause of the blinking red light or blinking yellow light that people suffer with their Playstation. This often occurs when people play their Playstation for extended periods of time because Sony did not build enough ventilation into the console.
So, how do you fix the blinking red light on the PS3? Unless you know a Playstation repairman, you will have two options. You can either send your console to Sony and let them fix it for you for $150-$300 or you can find a PS3 repair guide that will show you how to make the repairs yourself.
