Hey ya'll, I'm looking for some insight from anyone who has ever tried to repair an LCX unit by themselves. I know lowrance doesn't help and I'm not looking to start another argument about their customer service as that has already been done enough in other threads. My LCX 111c hd has had a problem with about 2in of the screen flickering about 80% of the time, some days it works perfectly though. Also, there is a problem with the sonar. You can actually hear it in the transducer (which is new). The pinging is very erradic and inconsistent (causing poor readings). Just wanted to know if anyone has ever had these problems/ tried to fix their own units with success.
