Blank Black Screen Issue on Fish Finder Need Help

[romromillys]

Hi everyone,

Blank Black screen appears on my Furuno fish finder when I power it on. The device seems to boot, but no display comes up.

Has anyone faced this issue or knows how to resolve it? Any suggestions would be greatly appreciated!

What is the model number? We can check and see if it is in night mode or the brilliance is cranked way-down. Try a blanket over your head, can you make out anything on the screen?
