Step-by-Step Guide to Fixing ThinkWay Collector Edition Rex Toy

The ThinkWay Collector Edition Rex toy, manufactured in China, is a 1:1 movie-scale replica featuring voice-activated functionality. When exposed to external sounds, it moves its head and two front claws while emitting sounds. Twisting its tail can also activate it. Additionally, removing the speaker reveals two contact pins for “Try Me” mode.
Based on my experience repairing dozens of these units, the most common issues are as follows:
- Over time, significant grease buildup occurs inside the toy. It’s unclear where this grease originates, but the internal circuit board and components are often coated with oil residue. If the voice control fails or becomes unresponsive, the microphone component is likely the culprit.

Disassembly Steps:
- Start by removing the tail, then unscrew the 3 fasteners.
- Detach the circuit board. Inside the torso, you’ll find the speaker housing, which may require forceful prying to open.
- After removing the speaker, disconnect it to access the microphone. Replace it with a new one of the same model, soldering it in place with a soldering iron.

2. Faulty Mode Switch & Wiring Replacement


Problem: Due to internal corrosion, the PLAY/Try Me mode switch fails, and connecting wires to the circuit board corrode requiring replacement.
Solution:

- Replace with a compatible switch (exact matches are rare).
- Pro Tip: Aftermarket switches may require removing the keycap, but functionality remains intact if wired correctly.
Crucial Step: Reconnect wires to the new switch exactly as the original configuration—this is critical for proper operation.
3. Battery Compartment Failure
This is a common issue in Collector Edition Rex toys. Since batteries are pre-installed, even unopened boxed units can suffer from battery leakage corrosion on circuits after prolonged storage. The battery cover’s unique shape requires DIY repair of its metal contact plate. Refer to my illustration below for guidance.


In summary, this covers the most common fixes for the Toy Story Rex collectible toy. If you have questions, feel free to ask in the comments!
