Lowrance 3400 User Guide

The display on my OEM installed 3400 does not work. I can hear the shallow water alarm so I assume the transducer and cpu are working.

Since this is an old model does anyone know where to find replacement displays or if there is a compatible unit that utilizes the transducer puck in the bilge? I do not want to drill anything to my transom. ATTACH=CONFIG152323/ATTACHI happen to have this same 3400 depth finder with an excellent display unit. My problem is water got into the separate main circuit black box.
