Hisense 50h6d with power supply board 214274 will not power on after a storm. My security system that was connected through HDMI to this tv also stopped working. Thankfully after replacing the power wall plugs and using a different tv, same model, it worked. Tv still dead. T.v. was plugged directly into the wall. My son is tech savvy, in college for electrical engineering. He also builds robots. I know he can fix it if I purchased what it needs but I can't figure out the right things, if any, to buy. I know it's not just the cord like with the security system, could it be? Power supply board? Fuse? Main board? Possible place to purchase items? Any help at all would be greatly appreciated.
