the next day i took it completely apart to check the leds....here is the dust accumulation:
not too bad for 4.5 years and never having opened that section up...i would vacuum occasionally, but never that far in (that will change from now on)
i tested the leds with a 9V battery....red lit up, but green and blue did not....so i assumed that my screen went dark because two leds were out
here is a photo of the blue led, notice the pins on the one side that look distressed:
when i got the blue and green leds that i ordered, both tested fine when i connected leads to my cell phone battery...i decided to try that on the old ones and the old blue one lit up!
so i decided to simply change out the green, pictured here:
there was no distressing similar to the blue one, but the die(?) in the middle had a couple of discolorations (not visible in photo)
i took off the old, cleaned the heatsink with rubbing alcohol and added arctic silver 5, put it all back together and it worked like a charm!
