Solid blue light means that your system is booting up. However if your unit gets stuck booting up, here are ways to possibly resolve it.
1: Hold down the power button on the back until all three lights blink red. Once the unit is off. Go ahead and try again.
2: Power off your SkyTrak unit and then take the SkyTrak unit away from your home Wi-Fi network and try to power the unit back on to see if you can get more then single blue power.
3: If you are still stuck on single blue power, please reach out to support.
