I have a Sugden CD21, the original version that matches the A21a.

Player works fine but the display has developed an anoying flicker. It does not go out but dims slightly in a kind of a wave pattern running from left to right accross the display at approx 1 sec intervals. Really distracting.

Anyone come accross this and know of a cure, thinking it might be a faulty part, a cap, or diode in display circuit but not sure.

Any suggestions?
