I have an A70 board, so not a switch problem, I have removed, wiped doen the edge connector, it already looked good and reseated it. That didn't help.
?As a troubleshooting method can I remove the A70 PCB, can I close the A60S2(2) switch, then rerun the CAL.
If it doesn't respond with CE-F, can I conclude a problem with A70?
???????????????????????? Thanks, Lamont
