On 2020/03/09, I tried to re-test M1586, but it was not programmable. Visual inspection revealed nothing to me. I did re-insert the cable once again, but this time this did not help.
Maybe one should try again re-inserting the cable.
Maybe these issues are an indication that the module (MOLEX) is flaky. |
Most likely the cable contacts caused such behavior since they look damaged.
After changing the cable module do not show any more problems. |
