All my fluorescent lamps are flickering or won't start. New lamps made no difference. So it must be either a starter or a ballast. I couldn't find a starter so I am assuming there isn't one, and the ballast is hidden somewhere under the cover. There are a million videos on youtube on how to replace a ballast but not a single one, not a single schematic or how to tear it apart and test it. Of course I am going to buy a new one but I am just curious what this thing does other than limiting current. And what can possibly happen to it with time.
