Continuing with my A3000 restoration project, I'm going to attempt this today. It looks like a simple resoldering job. Anyone done this before?


Yes, in my case it was very easy. Look at the back of the board while you wiggle the led. See if the solder joint is comprimised. In my case it only needed resoldered. Also the the LED is basically a diode. Using a DMM you can check the continuity at the lead ends. One way the resistance should be very high high (very high megaohms or infinite-open). The other way the resistance should be negligible, almost zero. If you are getting a full open both ways (infinite resistance), then either the LED is bad, the solder joint is bad, or the wire is comprimised.
Someone has to state the obvious and that someone is me!
