ST60 Graphical repeater brightness

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Fourm PFishman,

By design, all of the ST60 Instrument displays should have had very similar brightness for each of their three backlight levels. As yours are not sufficiently bright and changes to increase the backlight level have not made them visible, then the backlight circuit of the ST60 Graphic displays would appear to be failing. Unfortunately, Raymarine can no longer service ST60/ST60 Instrument Displays. This class of instruments would typically be replaced with i70 (replaces ST60 Graphics), i50 Triadata, and i60 Wind.
