My no brand digital clock is beginning to flicker. Numbers are the
illuminated kind, 7 segments display and not LCD. Powered through USB

 I have been using it for about five years. Most evenings I switched it to
the touch sensor so display is actually off for the night. Trying to extend
the display lifetime.
 There’s anything I can do to fix it? Thanks for sharing.

Could be a fault appearing in the mux circuitry. In most such displays all the same position segments are connected together and each number selected one at a time in turn. When done fast enough the human eye doesn't notice the chasing.
Mind you that's probably all done within the main clock IC so not much else to go wrong. Any chance of getting the clock open and posting the main IC device number?
