Hi my name is ***** ***** Im here to give you a hand with this issue.
When a ballasted light begins flickering (often accompanied by a faint buzzing sound), it's an indication that the ballast is on its last legs. The only real option, is to swap out the ballast.
If this is a residential application, it's easy enough to do yourself.
The only info you need for a new one is the voltage, number of lamps and style/length of lamps.
I would suggest taking a picture of the old connections prior to removing or cutting any wires. Typically you have your power in on black/white, a ground, a red wire out to the tombstone (the piece the light end fits into) and a blue return wire.
If there are more than 2 bulbs, then you will have alternate combinations of red/blues.

The blue return wire will go to the opposite tombstone as the red I mentioned previously.

As a caution, do not do any of this work on a live ballast. The output voltage of the ballast is much higher than the incoming line and can cause serious injury or even death.

-Purchase a new compatible ballast using the requirements I've given.
-photograph the connections
-cut out the old ballast and remove
-install new ballast as per your photograph. You will just be matching up the colors.
