Disassembling the device
ID: 237510
Description:
Steps:
- Remove the batteries.
- Remove the plastic cover on the bottom. (On older models, this cover is not centered.)
- Remove the small screw.
- Use a flat blunt tool to loosen the ribbon cable clamp. To do this, pull the front part away from the rear part.
- Pull out the ribbon cable.
- Put the batteries back in (without screwing the cover on).
- Push in the batteries to release the circuit board assembly.
- Carefully pull out the circuit board assembly. Pay attention to the ribbon cable.
- Soak the keyboard in alcohol (methylated spirits). It should be completely covered. Use an airtight container.
- Keep moving the container to get the liquid everywhere.
- Wait 24 hours
- Take the keyboard out of the liquid and shake it out well.
- CAUTION!! This step is not absolutely necessary!! Opening the keyboard further is only necessary if you want to gain access to the circuit paths.
- The plastic cover on the back can now be easily detached. To do this, use a flat blunt tool to go into the gap and pry off the plastic cover. The alcohol has softened the glue.
- Let the keyboard dry well. To speed up the process, you can put it into the sun.
- Put the parts back together in reverse order. When installing the circuit board unit, make sure that you pull the ribbon cable to the side.
