Hi
First time posting so hope this is in the right section.
Trying to repair a friends Makita DAB radio board which has decided to melt itself. I'm looking for a bit of help identifying two surface mount components. I've uploaded pictures of a good board that I've managed to borrow and use as a reference and the bad board just so you can enjoy the burnt up destruction.
The first is what I believe to be a zener diode labelled 'L2' (D1 on PCB). Found a little info but two datasheets giving two different voltages, so a little confusing.
The second is the 3 node component that looks to be a transistor labelled as 'BR'. Found no info regarding what the values of this might be.
Any help is much appreciated!
