LED diode replacement Aquatic Life Halo

[Acrofiend]

I have two cool white diodes that aren’t turning on so I’m assuming they’re dead. How hard is it to replace them myself?
I also noticed there’s unused spots (D3, D10, etc). Is it possible to add LED’s in those spots?

Not that hard although a hot air rework station might make it easier. I would definitely try it if it were me.

Thank you. I used a hot pan and it worked which was a hassle because the heat from the pan and size of the LEDs.
Only thing is some of the LEDs aren’t on now so I assume the weren’t soldered correctly -_-

I also added LEDs into the empty spots. Do you think this turned off the other LEDs in place of these?
