Famicom DIY AV Mod Kit: Is Composite Video Worth the Soldering?

Review of the Famicom DIY AV Mod Kit for Composite Video: what it changes, who it suits, and whether its no-cut connector installation justifies the required teardown and soldering.

Last updated Aug 5, 2026

For a gaming replacement parts modding project, the key decision is whether to open an original Nintendo Famicom and solder an internal modification for AV composite-video output. The Famicom DIY AV Mod Kit for Composite Video targets that specific goal, while its installation description says no housing cutting is required for the connector. At USD 47.99, the decision turns on whether that video-output objective justifies the hands-on work.

Quick verdict

This kit makes sense for a Nintendo Famicom owner who specifically wants AV composite video and is prepared to handle console disassembly and soldering. Its clearest practical advantage is the no-cut housing detail: installing the connector does not require cutting the Famicom shell. The central trade-off is the amount of internal work, including removal of the existing POWER & RF board and soldering multiple connections. It is a focused modding component rather than a simple external setup.

Who this kit suits

Choose it when the console being modified is a Nintendo Famicom and the desired result is composite-video output from an original Nintendo Family Computer. The project is a reasonable match for someone willing to remove the bottom cover, disconnect the controllers, access the motherboard and power board, and complete the required soldering.

It may be a poor fit for a project that needs to avoid opening the console or working on its internal boards. The installation is not limited to attaching a connector: the described sequence includes board removal, desoldering, and a separate power-switch connection.

Famicom DIY AV Mod Kit for Composite Video

The reason to choose this kit is its clearly defined purpose: AV composite-video output for the Nintendo Famicom, with connector installation that requires no housing cutting. The installation sequence begins with removing Phillips screws and the bottom cover, disconnecting two controllers from the motherboard, and removing screws from the motherboard, power board, and power switch. It then calls for desoldering the seven wires connecting the motherboard to the power board, placing the mod kit, soldering those wires, and soldering the power-switch line.

The limitation is equally concrete. This is a DIY internal modification that requires board access and detailed soldering, so the kit is not suited to a hands-off approach. The listed compatible model is Nintendo Famicom, making the intended console specific rather than broadly universal.

What stands out

The no-cut connector installation separates the kit's physical approach from a modification that requires altering the console housing. That can matter to owners who want the shell left uncut while still pursuing AV composite video. The instructions also describe removal of the existing POWER & RF board, so the project changes the console's internal setup rather than adding only an external connection.

Meaningful trade-offs

The main trade-off is clear: the housing does not need cutting, but the console still needs substantial disassembly. You will need to remove screws, disconnect controllers, desolder seven wires, and solder both the replacement connections and the power-switch line. The USD 47.99 price should therefore be considered alongside the time and skill required for this particular mod.

Bottom line

For a Nintendo Famicom owner pursuing AV composite video, the Famicom DIY AV Mod Kit for Composite Video offers a defined internal-mod route with a no-housing-cut connector detail. Choose it when the compatibility and video goal match your project and the board removal and soldering are acceptable. If the installation work is the deal-breaker, that DIY format is the kit's central limitation.
