PS2 owner filmed a dramatic video about the graphics chip failing right during a race

A short clip filmed by a CRT gaming enthusiast starts out as a regular race down a coastal track. Then the yellow car and the surrounding environment start breaking apart into polygons, textures slide off the models, and the sound loops while the music keeps playing normally. The whole thing ends when the picture collapses into solid blocks of black, white, gray, and shades of pink.

The failure traces back to the Graphics Synthesizer, the chip responsible for all rasterization on the PlayStation 2. It ran at half the clock speed of the Emotion Engine and used an unusual architecture for its time, with memory built directly onto the die.

That setup explains why the picture fell apart gradually instead of all at once. Geometry kept streaming to the chip, but the frame buffer and texture memory started returning corrupted data, sending vertices flying off to random coordinates. The console kept trying to render the scene right up until the end, filling in garbage where correct values should have been.

The looping audio works on a similar principle. The audio stream passes through a buffer that smooths out uneven data delivery, and once new fragments stop coming in, the system just keeps reading the same chunk of memory over and over. Anyone who has ever pulled a cartridge out of a running handheld console has heard the exact same effect.

Failures like this after two decades usually come down to a handful of causes. Solder joints under the chip degrade and develop microcracks, which sends incorrect voltage to the pins. Capacitors drift from their rated values after twenty years, and in bad cases the electrolytic ones leak and damage the traces on the board.

Repairs aren't always possible. Reflowing the joints with hot air sometimes restores contact if the problem is limited to the soldering, but once the die itself has degraded, the only fix is swapping in a chip from a donor board.

The owner of the "fried" PS2 noted that the console still powers on, but the video output stays dark, and the loading screen audio can be heard falling apart in the same way. The board got set aside for parts, and its replacement is the exact same SCPH-39001 revision.
