Today's consoles are more complex and have more components then your good ole N64.
Please don't use that PS3 "FIX" youtube video as a repair guide. All you will end up doing is damaging it beyond repair. Im talking about you KingsOvAllKings.
If you haven't butchered the PS3 yet, send me a PM. I repair XBOX 360's and PS3 with professional rework tools and procedures.
If you don't want to repair your system ill buy it from you. I also have XBOX 360's and PS3's available for purchase. The systems I have for sale are NOT YLOD/RROD repairs.
