Ring pro power issue

my ring doorbell pro is not turning on when connected to ring ac adapter. when i connect it using usb cable, the blue light spins and then solid white light. but then it turns off and this cycle repeats again and again. what should i do. the ac adapter is giving correct voltage (26VAC) as tested by multimeter. any suggestions

Hey @ksri82! It looks like you’ve covered the basics to ensure sufficient power is reaching the device. I recommend allowing the Pro to remain connected to the power for some time before attempting a setup. Otherwise, it may be best to reach out to our support team, at 1-800-656-1918, for more in-depth troubleshooting.
