If this happens, you need to switch off your PS3 and let it rest for a even though. It can be advised that you let the console rest for 24 hours. Right after that, you are able to turn it on and see if it works once again. Generally, there won't be any red light blinking dilemma soon after you might have given the console rest for 1 day.
My cousin had the same problem, he looked at some guides online. So apparently, there are a couple guides out there. But when I asked him he said he bought the “Paul Thompson version”, apparently the guy runs a PS3 fixing business.
