AV Troubleshooting

Video and audio problems on the Dreamcast usually come down to the cable, the video mode, or a mismatch between the two. Working through them methodically will resolve the large majority of cases without opening the console. AV

No picture at all

If the screen stays black but the console powers on, the most common cause is a VGA-incompatible game booted in VGA mode, or a display that does not accept the signal. Try a different cable type, confirm the television input is correct, and test with a game known to support your video mode.

Wrong colors or rolling image

A picture that is too dark, tinted, or scrolling vertically often points to a sync or wiring issue, frequently with a poorly made RGB SCART cable. Swap the cable and confirm your set actually supports the signal it is receiving.

• Soft, blurry picture: you are likely on composite; move up to S-Video, RGB, or VGA.
• No sound with VGA: expected, since VGA carries no audio; connect the separate audio outputs.
• Intermittent signal: reseat the AV connector and clean the contacts.

Region and refresh issues

A console and game from different regions can produce a bordered or mis-timed picture. A region-free loader or matching software usually fixes this.
