Retro console recap and power repair.

Signs you need this repair

Sound familiar? The diagnosis is always free.

• No power light at all
• The power light comes on, but there’s no picture or sound
• The screen is faint or the sound is weak, crackly or missing
• It only works after warming up, or after flicking the switch a few times
• It works on batteries but not on the power adapter, or the reverse
• Green or white crust on the battery contacts
• A fishy smell or brown residue near the capacitors

Why old consoles stop powering on

Most retro consoles are 25 to 40 years old. Parts that were fine for the first decade or two are now wearing out in predictable ways:

• Aging capacitors. Electrolytic capacitors dry out or leak. Leaked fluid is corrosive and eats into traces on the board.
• Battery corrosion. Batteries left inside a handheld leak and corrode the contacts, springs and nearby traces.
• Worn power switches and jacks. Contacts oxidize and loosen, so power cuts in and out.
• Blown fuses and tired power supplies. Common on consoles with an internal power board, such as the PS1, Saturn and Dreamcast.
• The wrong power adapter. Universal adapters set to the wrong voltage or polarity can blow a fuse or damage the board.

What a recap is, and when you need one

A recap means replacing a console’s old electrolytic capacitors with new ones of the correct values. Capacitors smooth out power and carry audio and video signals, so when they fail you get dim screens, weak or crackly sound, or a console that won’t start.

Some systems are famous for it. The Sega Game Gear and Nomad, the Atari Lynx and other handhelds from the late ’80s and ’90s use small surface-mount capacitors that leak with age. On those, a full recap is often the real fix, and leaving leaked fluid on the board only makes the damage worse.

Other consoles rarely need one. A Game Boy that won’t power on usually has corroded contacts or a worn switch, and NES, SNES and N64 power faults are more often the switch, the jack or the power brick. We don’t recap by default. We find what failed and quote that.

Power repairs by console

• Game Boy, Pocket and Color. Corroded battery contacts and worn power switches are the usual culprits. We clean or replace the contacts and repair any corroded traces.
• Game Gear and Nomad. Capacitor leaks cause faint screens, no sound and no power. A full recap and board clean usually bring them back.
• NES, SNES and N64. Usually the power switch, the power jack or the power supply. A blinking NES power light is a connector problem, not a power fault, and is fixed by cleaning or replacing the cartridge connector.
• Sega Genesis and Master System. Power jack and switch wear, plus capacitor issues that affect sound on some models.
• PS1, Saturn and Dreamcast. The internal power supply board is a common failure. We repair or replace it.

What happens during the repair

1. Open the console and inspect the board for leaks, corrosion and earlier repairs.
2. Measure the power path from the jack or batteries to the board to find where it stops.
3. Clean corrosion and leaked capacitor fluid from the board.
4. Replace failed capacitors with quality new ones of the correct values, and repair damaged traces.
5. Clean or replace the power switch and jack where needed.
6. Play-test with a cartridge or disc long enough to confirm stable power, picture and sound.

How much does a retro power repair or recap cost?

Retro power repair and recaps start from $59. The price depends on how many capacitors your console has, how much corrosion or trace damage there is, whether a power supply board needs replacing, and whether we find other faults, such as a worn screen or dead buttons. We quote after the free diagnosis, before any work. If you want more done while it’s open, such as a backlit screen mod, we can include it in the same visit.

Before you send it

Take out the batteries first, even if they look fine. If you use an unusual or original power adapter, send it along, since it may be the fault. Remove cartridges and discs, and pack the console so nothing presses on the screen or switches. A short note on what happened when it stopped working, such as a smell, a pop or a new adapter, helps us find the cause faster.
