I have a alisun 300/400 series which was already dismantled when I bought it and was told a few of the tubes 2/3 in fact needs replacing
So the first I fired it up this was the outcome

Only 5 bulbs out of 16 on top only work
2/3 starters had Burnt out and gone a weird shape
3 trays ballast stay cold after running it appox 12 mins ...would that be related to the same bulbs ?


Changes made:
I've changed bulbs = no change
Changed starters in majority of top bulbs from Philips s12 to same but black in color = more bulbs won't come on in blocks of 4 now
Also 2 bulbs on bottom not working now
Tightened all wires connectors
my question is could the wiring to ballasts be wrong before I start thinking they have a fault because of them not getting warm when it's running any help in where to start on the fault finding and order would be really useful
With regards Lola
