Re: LCD TV and Monitor basic troubleshooting guides

Hello dear, I live in Argentina and I try to repair TV. In this case it is a 55 "Samsung TV, model UN55J5500AG. That due to a lightning in a storm burned the power board, I replaced it with a new one and with bad luck that the mainboard also has problems. The forum and find similarity with the schematic that comment, as the IC Z3015PI1, fundamentally, and I saw the photos uploaded, and although it is not the same mainboard, it is very similar.And I have the same problem I burned the IC207, in my In case of the IC206.
My concern is to find the schematic of the mainboard. You will have this schematic. And know if they could fix it. From now many thanks and greetings.
