Re: Digital clock with seven segments display flickering

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

A dying LED does not flicker, just looses brightness (white lighting LEDs do blink, but that is a thermal problem with chinese crap).
The power supply (external or internal) may be oscillating; Change the external supply or look for dry capacitors in the internal one (if any).
