Problem:
OBDSTAR iscan Ducati diagnostic scanner failed to turn on even connected to Power Supply.
Possible Causes:
Battery is depleted.
Mainboard failure.
Troubleshooting and Solutions:
1. Connect the device to the power adapter and check whether the power indicator light turns on.
If the indicator light shows red, this indicates the device is charging. Allow it to charge for at least 30 minutes before attempting to power it on again.
If the device powers on, the issue was caused by a depleted battery. Fully charge the battery to resolve the issue.
If the device still does not power on, the problem is not battery-related.
Remove the back cover, disconnect the battery cable, and power the device directly via the mainboard (using the power adapter). Check if the device powers on.
If it powers on, the battery is faulty and requires replacement.
If it still does not power on, the issue is unrelated to the battery.
After ruling out battery issues, the problem is likely due to a faulty Android mainboard. Replacement of the Android mainboard is recommended.
2. If the power indicator light does not turn on at all when the power adapter is connected:
Try connecting the device to a vehicle's power supply using the OBD main cable. If the indicator light turns on and the device powers up, the power adapter is defective and needs to be replaced.
If the device still shows no response even when powered via the vehicle:
The Android mainboard is most likely faulty. Replace the Android mainboard first to eliminate this possibility.
If replacing the Android mainboard does not resolve the issue, the VCI (Vehicle Communication Interface) mainboard is likely defective and requires replacement.
