i have one of the old school first gen PS3 and i guess the age has started to catch up on the system. one morning i was going to let my 7 year old watch Blu-Ray on the PS3 and it won't turn on & saw the blink in a color that i've never seen before... Yellow. I came straight to this sight & found out about the YLOD!
I got the PS3 YLOD Fix Kit and got my ipad out and sat on my living room floor with baby food tray for screws and decided to get going. at the time, i didn't think it'll take too long since i've taken xbox360 apart many times. but i should of known when the difficulty rating is "difficult" and required time is "1 hour", i should of sat at my work station >.<
one thing i've noticed was there was tons of dust build up even i vacuum the system anytime i use the vacuum. so, since i was taking it apart, i got my dyson and duster out and cleaned while getting down to the mobo.
after redoing the paste & stuck the new thermal pads, reversing the process was not bad at all. i thought with so many screws, it might become a problem but as long as you use anywhere to divide the sets into small sections, makes life lot easier. Though one thing that i messed up going in reverse was to hook those hinges on the metal plate. i actually had to go back little ways to fix that problem.
even after making simple mistakes, i was done in an hour. being prepped for the worst made things lot easier & especially with the guide ^_^
Get a tray to divide the screws from each section of the system, later on it makes life so much easier. when going in, i think it might be good to clean out the dust since you wouldn't want to open this up just to clean. some people may want to have small needle nose or something to pull screw from tight spaces.
