@feya old question and only answered for completions sake. That is reference designator L9500 which is a 250 Ohm ferrite bead (fixed inductor)in a 0603 package.
You will need to check why it blew the way it did. There should only be 12 Volt on that rail, so make sure you have no short anywhere else.

Feya, I have this exact same problem!! This has to be a design defect. Same resistor blew out on my board and my screen won't come up. Did you find out what the value of the resistor is? Thanks in advance!
