| + | [title] Find and verify the fuse |
|---|---|
| + | [* black] Below the bunch of big capacitors is a fuse with the designator "FUSE1". This device is placed behind the 3,3V regulator, right in front of the 1,2V regulator. So your system does not have 1,2V and one of the main controllers of the ESC does not work any more. Hence the glowing display, which is not run on the 1,2V rail. |
| + | [* black] Check, that this fuse is really broken. You may do this by placing a continuity tester on both ends of the fuse while the device is switched off. There should be no continuity if the fuse is really gone. Or you might test the voltages on both sides. If the fuse is gone there should be 3,3V on one side and nothing on the other. |
