The grille light doesn't light, it's Square, and the switch has to be slowed before it is turned on, and some of it still flashes a few times before it turns on
Because this is an electronic starter, a starter. This is slower than others, and the chandelier is a DC voltage
Because it is impossible, the 3 sets of tubes, rectifiers, and starter are all broken, and if one is the latter, one of the rectifiers or the starter is not working
There should be a problem with the ballast. Try a new one.
