Question about Lowrance LCX-27C GPS Receiver
Unit has been working fine. I have cleaned all connections and sprayed with silicon. Still no-go.

It sounds like you may have to send it out for service, but before you you do there are a few things you can try.
Low voltage can cause erratic behavior. Since you already wired directly to the battery, check the plug for corrosion.
Try unplugging the transducer cable to see if the display still behaves erratically. You wont see depth readings but you should still see the screen going black. If no erratic behavior with transducer unplugged then problem is in the transducer cable or the plug. A common source of failure is at the plug because the added stress of plugging and unplugging cables can cause the socket to twist slightly which can cause a short.
Make sure you have the latest software update.
How to see if your LCX-19C is already using version 1.8.0 software:
Copy it onto a blank MMC card and install it in your GPS. The GPS should prompt you on how to install the update.

i've repaird this by installing a secondary powerswitch and disconnecting the power switch on the keypad. It's an involved repair but it can be done.
