Sega Genesis and Mega Drive repair
1989–1997 · Mail-in from anywhere in the United States, or drop it off at an event.
Model 1 and Model 2 Genesis consoles fail in different ways. The Model 1 has the better sound and the more fragile power and A/V jacks; the Model 2 is tougher but its audio circuit is known for going muffled or noisy as the capacitors age.
Both share the Sega cartridge slot, which grips well but fills with dust, and both are easy machines to work on once they're open.
Common Sega Genesis problems
Black screen with the power light on
Dirty cartridge slot or cartridge contacts.
Buzzing, muffled or distorted audio
Aging capacitors in the audio section.
Picture rolls or drops out when the cable moves
Worn A/V output jack or a cracked solder joint.
No power
Failed power supply or a damaged barrel jack.
Sonic 3 saves vanish
Not a battery — Sonic 3 uses FeRAM; a save loss there points at the cartridge board.

Console work carries a $35 diagnosis fee per console, credited toward an approved repair. See the full pricing page for everything else.
Genesis power supplies are not interchangeable with other consoles even when the plug fits — the polarity differs between models and the wrong brick can do real damage. Send yours with the console.
Battery-backed Genesis carts are rarer than people assume. Phantasy Star and the sports sim library use them; most of the catalogue does not.
Sega Genesis questions people ask
Why does my Genesis have no picture?
Start with contact: a dusty cartridge slot or dirty cart contacts cause most black screens. If clean cartridges still won't show, the A/V jack or the video circuit on the board is next, and board repairs run $99 to $149 after diagnosis.
Can the muffled audio on a Genesis Model 2 be fixed?
Yes — it's usually the electrolytic capacitors in the audio path drying out with age. Replacing them is $79 plus capacitors and brings the sound back to where it should be.
How much does Sega Genesis repair cost?
A cartridge slot clean is $29, a full teardown deep clean is $45, A/V or power jack repair is $65, and capacitor replacement is $79 plus capacitors. Board-level no-power or no-video work runs $99 to $149.
Do you service the 32X and Sega CD add-ons?
The 32X connector and pass-through are serviced at $65. Sega CD work is limited to the cartridge-side and power-side faults — no disc drive or optical repair.
