Hello, I am having trouble getting an S-52+ controller to boot up. On power up, it will run through the startup on the TP, but the freezes on before the Kawasaki logo screen. The last line shown on the TP is "Kernel: Loop Forever". I have connected to the controller with KCwin32 via a null modem cable, there is no information shown there either. On power up, in KCwin, a dot appears on screen, then once the boot sequence should finish a bunch of blank lines are pushed and I am not able to input anything into the command prompt. So far I have: -Replaced the 1RA board with a brand new one (three times) -used the original 1QJ board -used a new 1QJ board -used the original 1KK board -used a new 1KK board -removed the 1KK board -used four different AS Software versions -used three different SV Software versions -Replaced the 1SP Board with a brand new one (twice) -Replaced the 1QZ Board with a brand new one -Replaced the TP -Removed the TP -Replaced the batteries on the 1QZ board and the encoder -Removed all wire harnesses from the controller -Probably a couple things I'm forgetting Between each change power was cycled but always the same result. Except once, it did boot up properly. I disconnected the battery located on the 1RA board (desperate attempt) and the controller did boot up properly. I received all the expected faults, including one saying the battery had low voltage. I was able to clear all the faults except that battery related one, but couldn't Master On the robot in teach. So I powered down, connected the battery, powered back up and it didn't boot up. I re-disconnected the battery and it still will not boot up. I'm really at a loss as to what the issue could be, since I've replaced basically everything in the controller and still have the same issue. Any help or guidance would greatly appreciated. Sorry for the long post.
