Hi
Something very similar happened to me, after I installed the speedball upgrade. I had to wait a month plus to get the replacement LEDs, I actually ordered quite a few.
In the meantime, while waiting, I tried some generic red LEDs that worked and lit up, so I was confident that nothing else was damaged. The sound quality did suffer a little though. May be more than just a little.
When the original LEDs finally came I replaced them and now I'm happy.
I hope you too have nothing else damaged.
