I have a TDA50 which had been turned off for an extended period of time. I turned the unit back on yesterday and the system just has a continuous flashing Run (Green) Light.

I've checked the SD card, which I am able to read from my computer, I've tried Initializing the system, I cannot detect the system when I plug it into my laptop via USB, and the phones don't turn on when connected directly to the system.

Does anyone have any suggestions?
