  Joshua BaldwinAug 17, 2025
  If your Motorola Cell Phone isn't powering on or staying on, here's what to check: 1. **Battery:** Measure the battery voltage with a 50 ohm load. If it's below 3.25 Vdc, recharge it. If it won't recharge, replace the battery. 2. **Connectors:** Inspect the battery connectors for misalignment or damage. Realign them, and if needed, replace the battery or get the connector replaced at a service center. 3. **Transceiver board:** Substitute the transceiver board assembly with a known good one. If it works, replace the original. 4. **Keyboard assembly:** Replace the keyboard assembly. Temporarily connect a +3.6 Vdc supply to the battery connectors. Press and hold the PWR button. If unit turns on and stays on, disconnect the dc power source and reassemble with the new keyboard assembly.

  If your Motorola Cell Phone has weak or distorted audio, or calls are frequently dropping, the issue might be with the antenna or transceiver board. * **Antenna:** Ensure the antenna pin is properly connected to the transceiver board. If it is, try replacing the antenna with a known good one. * **Transceiver board:** If the antenna isn't the problem, replace the transceiver board assembly.
