AV Troubleshooting
Most PlayStation video faults trace back to the cable, the sync signal, or a display that does not accept the chosen format. Work through the symptoms below before suspecting the console itself.
- No picture at all: confirm the cable is fully seated in the multi-out and that the TV is set to the correct input. If using RGB SCART, verify the input genuinely supports RGB rather than composite only.
- Black and white or no color: usually a region or signal-format mismatch (NTSC versus PAL) or a cable wired for the wrong standard. Composite-as-sync cables on an RGB-only input can also drop color.
- Rolling, tearing, or wobbling image: a sync problem. Switch to a cable with a clean csync feed, as some later boards output sync that confuses basic cables.
- Vertical bars or faint interference: often caused by composite video being used as the sync source; a dedicated csync removes it.
Isolate the variable
When unsure, fall back to a plain composite cable. If composite works but RGB does not, the console is fine and the fault lies in the RGB cable, sync, or display.
Wrong colors that look swapped or tinted frequently mean a miswired RGB cable. Do not assume hardware failure until you have tested a known-good cable.
Remember the PSone (SCPH-101) and early SCPH-1000 behave slightly differently from mid-life boards, so a cable that is flawless on one unit may need adjustment on another. Methodically swapping one component at a time will almost always reveal the culprit.
