Navigation System Backlight Broken?
Hey all,
Recently encountered a black screen issue with my 09 IS-F (Posting in the 2nd Gen forum for hopefully more visibility as I believe the F, 250 and 350s share the same navis). Ordered a display driver board and swapped it and the buttons light up again. However, the screen is still black unless I shine a phone flashlight onto it and see a very faint picture. The touchscreen, sound and everything works, I can even max out the brightness but without shining a light on it, it's almost invisible. I'm suspecting the backlight on the LED is also broken and was wondering if anyone here have suggestions on if I can replace the backlight or need to swap out the entire screen.
Thanks.
