38E: dot in upper left corner of display

[Dave Britten]

No dice. I cleaned off the PCB underneath both switches with a combination of Deoxit, alcohol, and pencil eraser, but the dot persists. It doesn't seem to fluctuate as much when jiggling the power switch, though. I'll have to check the voltages at the PCB end of the ribbon cable and see if there's a voltage drop happening somewhere between the batteries and the components. Every time I Incredible-Hulk the case open I'm sure it shortens my lifespan, though...
