Sounds like the light has been put into lock out mode by accident.
Your SOLA 1200 Video is a late model version that has the additional safety lock out mode ( shown by the lock on the control panel )
With the Light off , hold the switch in the forward position for 4 secs.
The light then turns on , then off, and the dashboard lights flash red 5 times.
The light is now in travel lock out mode and will not turn on.
The light will charge in this mode but will not switch on
To exit , hold the switch forward for 4 seconds.
The dashboard lights will flash green 5 times and the light then turns on
It should now be back on operation mode.
Take heart in knowing your not the first person the be locked out.
