Problem description
When the main board of the document camera cannot talk to the camera head, it will not finish its startup sequence.
Symptoms
Detail all measurable or observable symptoms in this section.
- After pressing the power button the power led correctly starts flashing, but
- The flashing never stops, and the document camera doesn't start functioning
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.
