I currently have a Depth Raider Drx-10 that has worked with no issues the past four years until two weeks ago when it suddenly stopped reading. My first steps were to replace the battery in the probe and re-coat the cable/probe connection. That didn't get it back up so I double checked the battery connection (good) and cut 5 feet of cable off and re-installed the probe the same as I had done previously, and then re-coated the connection (liquid electrical tape). When I turn the unit on I get the screen below for 5 seconds before it transitions to the "blank screen of death" in the second photo. Because I'd run it a dozen times this season prior to it failing I'm amazed that I can't get it to work. I should also mention that I run it off a separate battery to avoid any interference issues. Has anyone got any suggestions that I haven't tried?
