Solution
Diagnostic/Repair Steps
The most likely reason this can happen is that one of the connectors gets disconnected, either on the main board, or in the camera head. The connector in the camera head is more likely to become disconnected, however as a first step it's recommended to check the connector at the main board, because it's easier to disassemble the base of the camera.
Diagnostics and repair involves disassembling the device, and re-seating the connector.
- Disassemble the base of the device
- Check and re-seat the connector on Figure 1
- If the device still doesn't turn on, then:
- Re-assemble the base
- Disassemble the camera head (this is more difficult)
- Check and re-seat the connector on Figure 2
- If the device still doesn't turn on, then it may have a more complicated fault
