The photo above on the left shows JP1 with the green finish scraped off, and the bare copper exposed.
The photo above on the right shows JP1 bridged with a short wire soldered in place.
Note: If you can't solder, you shouldn't take your Tamagotchi apart. The red and black wires shown in the photos above are for the speaker and batteries. If you break any of them you'll get either no sound or/and no power. The only way to repair a broken wire is to solder it back into place.
Note: Even if you can solder, you shouldn't take your Tamagotchi apart. One slight slip of the soldering iron and you could break a trace or leave a solder blob in the wrong place. Either will ruin your Tamagotchi. The components and traces in the above photos may look small, but they're even smaller in real life.
Note: If you do decide to take your Tamagotchi apart, neither I nor TamaTalk will be held responsible for any damage, nor will we be able to help you repair any damage.
