LG 50LF6000 High pitch noise from power supply board

I have an LG 50LF6000. It's been making a high pitched electronic noise when powered off. I contacted LG and they got a replacement power supply board to a local repair shop over night and they just replaced it today. I'm hearing the same noise though.
Repair guy told me that if I still heard it, I should buy a new TV... thanks dude. Anyways, I've found the component making the noise. It's the part in the picture labeled 15S-LM06. Does anybody know what this is and if there's something I can do to fix this?
