Circuit board - anything glaringly obvious wrong with it after knocking it?

Just wanted to update in case it helps others in the future...

First I spent 10 minutes in the garage on my hands and knees looking for a 'jumper that may have been knocked off - negative result. Then I spent approx 15 minutes remocing the back cover and fiddling/poking every wire - negative result. Next I used a hairdryer to remove the flexible plastic trim that's glued on over the buttons meaning I was left with the bare plastic and no markings. I could see that the 'mode' button actually correlates with the 4 square pins to the right of the J5 that I thought I'd damaged. I noticed that the 'faulty' mode button did work when chaning between speed/distance on the manual mode so spent another 5 mins poking all wires. I then sprayed air over the circuit board, but didn't shake the can well enough and the liquid coated the circuit board. I then sprayed contact cleaner over the board and in the process managed to damage the LCD display which now looks like it has water damage. When I stuck the flexible plastic trim back on I realised I had also cracked one of the coatings that goes over the button.

Finally I RTFM and realised that you have to press the stop key before you change modes and the mode key is used to select the mode that you've navigated to AFTER you've pressed the stop key. Fixed!

After that saga I was expecting a word beginning with F, but Fixed was not the word I expected.  Well done.

Now that is one of the funniest posts I've read on here for a loooong time!

(Oh, it wasn't meant to be funny... :-(   )

Reading that reminded me of this old beauty from the Internet of long ago
