My depth finder on my E-120 works for a minute or 2 and gets stuck. My tri data also works for a minute or 2 and then the depth portion shuts off with only lines running thru and no numbers. Other portions of the tri data work and same with the E-120 screen

Hi! You will need to reset the unit to work normally. Try this, remove the battery and press/turn the power button for 10secs. while the battery is removed. Put in the battery and turn the unit on and see how it goes. This should reset the system and resolve the problem. Hope this helps and have a good one!
