I have a 400 watt hps ballast and for some reason it just wont light up i plug it in and it just makes this really loud noise it has done this before and eventually it starts to work again but i dont think its the bulb because like i said it s happened before and still works and i dont think its the ballast either i think its probably because i turned it on and of all of a sudden while fixing up my grow room but i wanna know if anybody knows of any type of quik fix for this situation? Any help is appreciated
