1. When the lamp is not on, check if there is anything wrong with the ballast.
Remove the lamp. Fix the safety switch on the right with tape and turn on the power.
Check to see if a blue flame starts igniting in the arc gap inside the ballast momentarily during start-up.
There is no problem with the ballast if there is a flame. When the ballast has no error, replace the lamp.
