Hi,
On my Meggy Jr, the second auxiliary LED D1 has mysteriously stopped working.
Any ideas what would of caused it to of stopped working?
I might attempt to remove the LED and put in my spare (if I can find it) but before I bust out the iron, is there anything else I can do to fix it?

There's nothing particularly special or unusual about that LED, so the first thing to do is to try touching up the solder joint at both points-- the most likely thing is *always* an iffy solder joint.
One other place that there could be an issue is on pin 14 of U3. U3 is the "upper" LED driver chip (by C2), and pin 14 is at the corner opposite C2, and it's not the pin at the very corner, but the one next to that.
If you need a picture of where to look, please e-mail me privately.
