My original PS2 and PS3 have both died, and I've nearly lost my second PS2 if I hadn't YouTube a rather simply solution for it, same with my second PS3. For both PlayStation units that did die, it was largely due to faulty hardware that the systems were notorious for having. The quick fixes for the current ones involved opening up the PS2 to clean out all of the dust that was preventing the disc drive to work, and the PS3 involved replacing the main power mechanism.

Nintendo has never really given me too much of an issue and I feel the cartridges themselves are usually the problem than the system itself. I did think I lost my NES a while back and even wrote a moving article for EoFF's sister site at the time for it. Turned out the only thing that went out was the A/V cable and the system worked fine.
