Merlin rollerdoor (Australian garage door brand) stopped working, when investigating I found a bug had shorted itself across an IC (labeled HVS004).

Luckily Merlin sells the whole replacement unit for only $449AUD. Before I pull the trigger on that I was wondering if anyone here could advise me on my chances of success if I just replaced the burnt bit.

I’m happy with larger electronics but I’m struggling to even identify any fuses on the board to check.

I’m also unable to find a replacement IC online as the code on it seems to be associated with some kind of blue LED. (I also don’t know for sure if the IC needs to be programmed or if it is just standard)

The back of the board is fine, just thru-hole solder connections.

here are some more photos(new link, should work now), hopefully in good quality.

Thanks in advance
