LG 55LE5400 No Ethernet - Port Dead, Grayed out in Menu

[jason123]

Hi Folks,
New to this form and I hope one of you can help me.  I have an LG TV that initially had a problem with USB ports, buzzing out of the speaker, flickering backlight when cold -  and so on.. I sent the board for professional reflow of the processors under heatsink and that fixed the USB issue and buzzing and flickering. TV works "Almost 100%" the HDMI port 1 is very touchy.

My big problem that I would appreciate some help on is the Ethernet.  This model comes Wifi ready, requires and adapter that didn't came with it.  But it has a LAN / Ethernet port.  However, in the menus (even after reset and firmware update to latest revision) is still grayed out.  No activity on the port when connected to a switch and I can't get it to "wake up"..

Any help is much appreciated.
Thank you
