Which power source did you use? (Battery or SMPS?)
If you were using SMPS, what was the output voltage of the SMPS?
If possible, please take a video and share it to us.
Thank you for the picture and additional description.
I'd recommend to replace the Fuse on the power board first.
1. Turn off the robot.
2. Disconnect battery and SMPS.
3. Open the back cover of OP2
4. Replace the fuse.
Then see if there's any damage on the cables and if everything looks fine, try turning on the robot.
Please let us know how it works after replacing the fuse.
After replacing the fuse, the situation is still the same. I guess it is not the reason that the fuse is short, and the fuse is not blown. The intel board didn't get up.
