i was wondering if any 1 had ne good techniques or like instructions for DESOLDERING then old green light and SOLDERING the new blues back in

 

just practice. Get yourself desoldering braid, a solder sucker and small rosin solder. This will run you 10 dollars at radio shack. Each costs 2.99.

just do it and you'll get used to it. When you solder on the circuit board. Don't let the solder touch any other metal connection around it. If you have too much just heat up the excess solder and either use the braid or the sucker to remove it.

 

i wish I would used those when I did mine, mine was a little messy but I got the job done
