Read the second part mate. If you tried the heatgun, and it didnt work, and then the hairdryer and it worked after that - there is a loose connection somewhere which expanded with the heat treatment. I open the PS3 several times, inside out, and I have seen a lot of components failed, and temporary spring back to life. I also have some soldering i did on the board (which is another story).
All im saying is that next time when it fail, rather take out the motherboard, and heat treat that alone. It will flex the board and temporary bring it back. Depends on how much you use it, in a few weeks (some say months, but for me it was 3 weeks) the hairdryer trick will stop to work, and the duration between fixes get shorter. So i did try it before, and as i am commenting on my own personal experience. However, i will not do the hairdryer thing without opening it, see the video on what can happen to the casing.
It will only melt if you leave the hair dryer going longer than 15min, but whatever I'm done discussing this with you.
