For what it's worth, I have repaired my HP-42S
Original Thread:
A very steady hand and several re-dos with the silver trace repair and I have a fully functional LCD again. I repaired about 6 traces in all. Thanks to all who assisted.
Now to make it "almost new" I was wondering if anyone has tried to touch up damaged brown paint on the faceplates of these calcs. Somehow the previous owner spilled something that damaged a small area.
I suppose I could buy a few model paints and start mixing to try and match, but was wondering if anyone has ever found an off the shelf match.
