L1 is a line RF noise filter choke as I suspected. Any differential noise* on the power line from the switch mode transistors or the wall outlet will cancel it's self out.
* Common mode noise is not as prevalent.
If that was a working LD player you could replace that with 2 jumpers and it would still work (though there could be more noise in the picture and sound with it gone).
Almost every modern switch mode power supply has one of those, and one from just about any other device that has one will work as a replacement...if you have a junk power supply from something else with a dual line choke like that that will physically fit it should be a usable replacement.
