Inleiding

Ga naar stap 1

The circuit board is the central component of the Little Tikes Tobi 2 Interactive Karaoke Machine, acting as its "brain" and enabling the entire system to function. It serves as the core hub to which almost every other part—such as the screen, speakers, buttons, and power supply—connects. The circuit board is responsible for processing inputs, coordinating actions, and sending commands to all components to ensure the device operates smoothly and performs its intended tasks. Without a functioning circuit board, the device cannot power on, respond to user interactions, or execute any features.

If you need to replace the main circuit board of your Little Tikes Tobi 2 Interactive Karaoke Machine, follow this guide.

Before you begin this repair, make sure your machine is off and the batteries are removed.

This guide requires soldering. Be careful when using the soldering iron as it is extremely hot and will cause burns. Refer to this guide on Soldering/desoldering connections for details on how to solder.
