Good day.
My first question of many on this forum. The led driver can work from 12-24v but was accidently connected to 52 v. Im new to electronics so my question is what can blow on the pc board so that it can be replaced. I'm not sure what component to identify as maybe a fuse or overload device. May someone please look at the attachment and help me id the components to test. Regards.

I do not see any fuses (and they aren't for "over voltage" protection anyways)..
Its likely that some of the chips were damaged by the over voltage.. Its junk.. Buy a replacement.

Well you don't seem to be getting a lot of responses. Rough guess, the 8 pin chip in the top left corner looks like a switching regulator. That might be a point of failure on an overvoltage input. Does it work?
