Okay so I have this problem with me play station console that has been really annoying me, I have the original PS3 that you swipe your finger of the button for it to turn on. Now at first the blue and green light turn on, than a yellow light turns on and off quickly, followed by the red light flashing. Sometimes I'm lucky and it will eventually turn on, but it usually just does the same thing - it sounds like the console starts up then the fan comes one, then just stops. What's the issue?
your ps3 finally overheated and cracked the solder. it's a common problem with the old, fat ps3s since Sony used a cheap thermal paste. combine that with the insane amount of heat those things generated, and you get that. sony will fix it for a price, or, if your warranty expired, you can do it yourself with your own thermal paste and a heat gun. the idea is that you use the heat gun on your gpu, which melts the solder so when it cools and hardens again, it "fixes" the cracks. it's called reballing, i think. re-flow is another way to do it, but it's a lot harder. i could be getting the terms mixed up, but the heat gun method is a common way of fixing the ps3. keep in mind it's not guaranteed, and even if it works, it might be temporary: when it did it for mine, it worked for about 1 minute. there are a lot of tutorials on youtube. good luck.
