nasty bit is that disturbing _anything_ will often 'fix' it. So you
think the last thing you did (resolded the LEDs, cleaned the backplane,
whatever) was the fix. And as soon as you get the case on, it's gone again.
Hi
Use care when soldering LEDs. They are quite sensitive to
soldering temperatures. Until I learned this, I had a lot
of intermittent LEDs. I've always use a heat sink on them
since ( pliers on lead ). Check to see if it is the LED
that is open inside by shunting it with a good one.
