I have a Ps3 that was bought in America. The power supply is different to ours here in South Africa (Cape Town). A friend who gave me the Ps3 also had an external power supply built so that it can be used here. It's been working for years but now I have that green light thingy going. I've removed the disc that was in it and thought it may have been inserted incorrectly. Now that I have seen your tutorial I will definitely check if it's the power supply or mother board. Thank you.
Once they have, you'll be able to view a graph of their reputation gained over time.
Here's a preview of what the graph will look like:
