Balance 20 status flashes red incessantly & won't reset

Hi,

Might anyone know I can access my Peplink Balance 20 hardware revision 1 router that does not display the web admin login page and does not reset? The lights on the LAN port respond to attempts to access 192.168.1.1, but other than that, the status light flashes red incessantly and nothing more happens.

Any advice or guidance would be very much appreciated,

Mike
