Need help identifying component

Hi,

I'm trying to identify some components that failed. Please have a look on the first picture. I found similar components on the board - the other two pictures.

The burned component has a code "L6", don't know what it is.






Thanks

L6 component is a power switching transistor. Still I can't find anything about the other, containing EY 5V. I suspect it is a DC-DC converter.

Any help is highly appreciated,
