Hi, Just joined this forum and am no electronics pro, just a hobby but I try. I have notices on 2 boards lately a black covex about 8mm dia. black what looks like resin of some sort, that traces lead into. Anyone know if there is an IC or something underneath? Also on the back of LCDs there is a larger convex black dot about the same. I have no clue what gives. Please share some of your knowledge with me. Sincerely John
