Stops on boot up

Same thing happened to my older model. Going to research it today. Mine was on a hot day and Matt have over heated. After recharging the battery it no longer comes on at all. Let me know what you find out if anything

here is the link to your the lowrance web site. the trouble shooting guide says that if you tried to it on another boat than you might need to take it in for service. but there is a section that explains how to do a soft reset on the unit. you might try that.

please rate and comment on your experiance with fixya.

If possible, try to restore the device to the newest firmware on it using your computer using this firmware:

OR
Do a soft reset. This may resolve your issues and will also keep your data on the device.
Do a soft reset by:
1. Having the device already off
2. Press and hold the PAGES key
3. Press and hold the PWR key
4. Release both buttons when the USA map appears

If neither of those work, try a hard reset. This will however delete all stored data off your device.
To do a hard reset:
1. Have device off
2. Press and hold the ZIN&ZOUT Keys at the same time
3. Press and hold the PWR key
4. Release both buttons when the USA map appears

If none of these work, contact Lowrance at 1-800-628-4487

You need to get a MMC card for it to show Canada.

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:

1. Press the MENU button twice on your LCX-19C.
2. Select SYSTEM SETUP.
3. Select SOFTWARE INFORMATION.
4. The software version for your unit is located under the line that says "LCX-19C" (ex. "Version 1.8.0").
5. If your version is the same version listed above, there is no need to download the software.

If it is lower than 1.8.0 you can download the update from this link: LCX-19C UPDATE
Copy it onto a blank MMC card and install it in your GPS. The GPS should prompt you on how to install the update.

If you need to send the unit in for service click this link: LOWRANCE SERVICE

Good luck!

Unfortunaley i have a problem with mine also. I contacted Lowrance, and they no longer support or repair this unit.
