I successfully troubleshoot and repair the PS3, demonstrating various diagnostic and repair techniques.
The red light of death usually indicates overheating, but it can also mean other bad components, i.e., the NAND chip, southbridge, and the CPU processor chip.
Usually, hardware failure is indicated with the yellow light of death, but some components can fail and instead trigger a red light.

This is slim so it won't have a yellow light.
Also, 3 beeps and flashing red lights can be caused by overheating.
