I have a Raymarine
unit (acquired with my Nic 38 2 years ago but I don't know how old) which works fine EXCEPT whilst during daytime the LCD display is clear enough, at night when illuminated it is virtually invisible with a very very faded antique look. I have tried holding down appropriate buttons for "a brief time" and "for one second" as suggested in 2 different manuals
but my unit doesn't seem to respond with any option to change best viewing angle etc.
I contacted Raymarine
and was invited to buy a ST7002 unit (for about £400 in the UK) since they don't have any spares for the ST7000. This would be a costly solution just to improve legibility. I have taken digital timers apart previously when the display dimmed, and found that cleaning
the mysterious LCD connectors (rubbery strips) and wiping them with WD40 solved
Has anyone encountered such a problem and found a solution which doesn't cost £400 or even $400? I am tempted otherwise to manage without my ST7000 display in the dark.
