Display Problems

I seem to be having display problems. What do you recommend?

Display problems can sometimes be mistaken for power problems. To determine if it is a display problem, the first step is to check if the keypad backlights (if applicable) are visible. For models without backlit buttons, it would be helpful to press the buttons and listen for responsive sounds. If the backlights are not visible, then the issue is likely related to power and not a problem with the display. Please refer to troubleshooting tips for power-related issues.  

Has Power but No Display

Here are some things you should check:

  • Adjust the angle and tilt of the depth sounder to ensure a clear view.
  • If your depth sounder has a contrast adjustment option, refer to the Operations Manual for instructions.
  • Check all connectors and pins for corrosion, including the power connector, depth sounder connectors, fuse, fuse holder, and battery terminal connections. If you find corrosion, clean it off using an abrasive like sandpaper or battery terminal cleaner, or a mixture of baking soda and water. Also, make sure all connections are secure, as corrosion can cause a loss of voltage to the depth sounder.
  • Remove any chart cards (Navionics, LakeMaster, etc.) from the card slots and try powering on again. Sometimes, a problematic card can cause the unit to freeze during startup.
  • Check if your unit is in "Night Mode" by pressing the power button once for HELIX, SOLIX, and APEX models while the unit is already powered on.
  • Shining a light on the screen can help you determine if there is a display issue with no backlight.

Display Freezes ,Stops Moving, or Touch Screen is Non-Responsive

Always make sure that your unit has the most recent version of software.  Software updates can be found under the Support section of our site. 

Erratic Touch Screen Activity

Water left on the Touch screen of your SOLIX or APEX can cause erratic activity, especially when in direct sunlight.

Although your Humminbird unit is waterproof, the air within the unit contains moisture due to natural humidity. Due to this, some fogging is normal on cooler days. The Spring and the Fall are the most typical times of year that we hear about this.  This situation is caused by heat generated from the sun warming the air in the depth sounder. The moist air is then trapped between the display and the lens in the front housing.  This situation can be avoided or reduced by storing in a protected and safe area at outside temperatures. The situation should clear after about one hour of use. If not, the unit can be sent in for service.  However please understand that we cannot stop a unit from having condensation under the above conditions.

If you have a glass bonded color display (in our 800 Series and higher products) condensation  cannot form as there is no void between the display and the lens.
