Hello all, The IC is LC7818. I hope that helps point us in the right
direction. I do have a scope but it is unreliable and am hoping to solve
the issue without it.
Thanks for all the help,
Gary


Ah. A 7818. That one does indeed have drives for indicator LEDs, in which
case I concur with abrsvc's contention that this is the most likely cause of
the problem.
