Good morning! Hopefully you all can provide some guidance, and thanks in advance.
We had used an s4cplus controller for some years without issue, then had an overheating issue about 2 years ago. We ended decommissioning this robot at the time, but would like to see if we can replace parts and get it back up and running.
Upon boot up (no robot attached), we see that the Teach Pendant has an infinite countup "Wait! Startup in progress. -->". After reading in some of these forums, here is some (hopefully) helpful information for troubleshooting:

I tried to use the instructions to delete the image.bin file and reboot, but with no luck. I couldn't get the prompt to pop up, even after hitting enter. So I would type and hit enter and nothing would happen except it would go to a new line (but no execution).
Given this info, I would suspect I need to replace the DSQC 509 board, but would love some opinion/confirmation before doing so! Additionally, do I need a functional robot hooked up to allow for the bootup to occur?
Thanks a bunch and let me know if there's any further information I can provide to help troubleshoot 
.
