I have a Raytheon RL9 LCD radar and the backlighting is almost non existent.
It looks like originally there were 6 or maybe 8 LEDS behind the screen, now
I am down to one.

Raymarine tell me that its not worth repairing, yet the radar is working
fine and apart from the backlight I have no reason to change it.

Has anyone taken one of these apart and can tell me if I am likely to be
able to change the LEDS?

thanks
