I don't often look for anyone to do this because I'm fortunate enough to know a shop that is authorized to repair electronics from most brands and now that the service manager of a well known local AV company has retired, they chose this place to service the equipment that is taken to their stores. They also sell and it's a small shop- if they were to become known for taking in boards from all over, it would take time away from their regular customer's needs. I searched using 'Component level repairs on Samsung TV boards' and found a lot of links- maybe some of them can do this. I meant more one that simply sold them as refurbished units. Might be handy if mine ever develop issues.
