Hello, I have two raster lamps and in them electronic ballasts GTV EEI = A2. Two of them turned off at once. I dismantled the ballasts and there are burned fuses and resistors. It's about R5 and R6. R6 and R7 are the same. Will you help me choose the right resistors and fuse?

Fuses and resistors fell for a reason. Probably the transistors too.

I will not even repair because I found a new one on the Allegro for PLN 12 a piece. It is known that the cost of repair would be lower but I will never have a guarantee or it will work after replacing the part.
