Flat screen Power supply repair

My 55" Visio crapped out, so I bought a new one ( I wanted a 65" anyway). Started looking into fixing the 55" to possibly re-purpose in the family room and my model had two boards connected by a header connector. Well the solder joints on the male side would go to hell. So I popped off the board, took it to work and re-soldered it and "Robert's your Father" it works great! Boys were watching uTtube on it yesterday while the wife and I watch Expedition Unknown on the 65".

I'm not an electronics guy either, I don't believe in that witchcraft black magic. I'll take a MIG over a soldering iron any day.
