Product Support - Display Troubelshooting

Here are some solutions that have helped many of our customers.

Cleaning the Screen
Warm water and soap will work fine. You can also use ammonia-type cleaners like Windex. Do not use any type of abrasive cleaners. They will remove the Anti-Reflection coating from the glass.

Electrical Noise
Other electrical devices on the boat can cause lines on the display. To determine the source of the noise, shut off all electronic devices on the boat. Power up only the Lowrance unit. If no lines appear on the screen, then start powering up other devices one at a time until the lines reappear. You may need to route the cables of the problem source away from those of the Lowrance unit.

Backlight Flickering
Make sure your electrical connections are clean and that your power source has a stable ground connection. Try resetting the unit according to the Unit Reset Procedure page. Also, make sure your unit has the latest software by downloading the update from the Software Updates page.

Touch-Screen
If your unit has a touch screen, use the menu to locate the screen setup or interface setup section. There you will find a Calibrate Screen feature. Touch that button and follow the instructions.

Remember that the touch-screen is pressure activated. Using the tip or back of your fingernail can help get a quicker touch-screen response.

Update the Software
Make sure your unit has the latest software version. Go to the Software Updates page to download the update for free.

Reset the Unit
Sometimes resetting your unit can solve unusual display issues. Here is a list of Reset Procedures for Lowrance products. Locate the one that applies to the model you own. Try a Soft Reset first, this will return your settings to factory defaults.

If you decide to try a Hard Reset, save any important stored data to an MMC or SD card or write the information down. The data will be deleted during this process.
