Hi all, acquired my first couple of robots from a factory, they appear to have been sitting unused for while. On power up the pendant shows the welcome screen and diagnostic warm start up procedure but shortly after the screen goes blank with a flashing cursor to the centre left of screen and remains blank along with the stop key LED being illuminated red. you can press any key and get an audible beep but the screen remains with the flashing cursor.
Could this be a faulty pendant? i'v checked that all the boards power up and all LEDS go out
Cheers
