The value in what you did was not the repair but the diagnosis. Did you identify the bad capacitors yourself or did someone else? Good work.
I have found that if something breaks, It is a pretty good bet that someone else has experienced the same problem.
Common problems wind up on internet forums and YouTube videos. The amount of DIY stuff available is staggering. In this case, Samsung actually had a class action settlement (expired) to repair the boards and there are multiple resources for diagnosis and repair.
