I have a problem with some of my Kuka KRC2 ED5 robots.
2 of the controllers won't boot up and show a blank, black screen at start up.
They have power, (incoming 27v dc.) the PC fans runs, the keyboard led caps lock/number lock leds function and the CD tray opens/retracts. but that it nothing further.
I've tries F2, F12, ESC & CTRL+ALT+DEL on power up but itthey wont boot up and the Pendants remains black.
I've replace the VGA card, System ram & CPU. re- seated the heat sinks on the CPU & North Bridge with new thermal past.
Powered up again and still no joy, finally I removed the whole motherboard, electrically cleaned it, inspected all the capacitors for leaks/bloating and then tested them all individually with a multimeter on either pin to check one side drained to 0v . All good, air dried it for 24 hours and re-fitted everything.
Powered up and still nothing !
I have now reached the limits of my ability and knowledge, so I'm hoping someone here has some ideas.
If the motherboard is beyond help then ........
Having done some research into Fujitsu D1688 motherboards and it looks like there are plenty of standard issue D1688 - A31 board around for under £50 , but the Kuka spec D1688 -K32 board is typically thousands of pounds !!! . As far as I can tell the only significant difference is the BIOS .
Has anyone here tried using Fujitsu's " DeskFlash" program to archive a copy the bios from a Kuka spec board to a standard one ?
So far I can only see there is only one small physical difference, in the absence of a power on pin on the K32 , but I'm ok with pressing a button to start it so , does anyone know any special reason why the a KRC2 Ed5 wouldn't run with a standard motherboard ?
