This my first post on this forum. I had to change a motherboard on a Samsung UE40ES5500WXXN. Unfortunately, after remplacement of the board, the Local set was gray and then it was not possible to correctly setup the TV. Looking on internet how to have unlock it, I found this page on your site .
I would like to share my experience and maybe ask for an update of the wiki: Using the Original SamsungTV Factory Remote and enter in the Service menu by pressing info & Factory when the TV is on. At this moment Local set and others options are unlocked.
Best regards and many thanks in the support to solve my issue.
