The normal operation is to alternately display "Digital" and "Analog", which it has always done. The alternations are at most a 1 Hz rate. The flashing is much faster, and involves a Light on/ Light off cycle. Not knowing how these things work makes it difficult for me to guess what may be failing, but my first guess would be a high voltage power supply. -Denis _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
