Reflowing those connections fixed it. It was a particularly annoying problem because just disassembling and reassembling the calculator would "fix" it for awhile, so every brainstorm I tried seemed to "work". (Hopefully Randy will stop by and suggest a more scientific approach!) Update: Some good suggestions from Geoff and Den in this thread |
