Lighting tube or ballast?

I've been in my shack 24 years, and don't remember if I ever changed the ballast in the flourescent lighting fixture above the kitchen sinks.

I have in the past, at more locations, changed the ballasts in flourescent lighting fixtures, but simply cannot remember if I ever replaced it in this
residence, in this lighting fixture.

The problem is that very often, when I turn the light switch on, nothing at all happens.

Then, if I put some sideways pressure on the light switch, and then push it up to the "on" position, sometimes more than once, the lighting tube does light up.

I did change the light switch and it is the same with the new light switch, so the problem is either in the lighting tube itself, or in the ballast.

The tube itself is turning gray on a very short distance on both ends.

So, how do I find out if I need a new ballast to solve this problem, and have the light come on very soon after I turn the switch up to the on position, and not have to repeatedly switch the light switch up and down before the light finally comes on.

After the light has been lit up for awhile, and I turn it back on, there is no delay in the tube lighting up.

So, how do I determine if the problem is in the light tube, or the ballast, or both?

Change the tubes, and if it works now, you are good.

If the new tubes fail after less than a year, change the ballast.

Hi, switch to the LEDS now , by the time you buy bulbs and if they don’t work you need a ballast you have almost paid for the LEDs.
