Unplug all connections to the TV, unplug the power and wait 10 minutes. Connect ONLY the power to TV and BR player then HDMI for the player to the TV.
I don't see a BR player model but be sure it's reset too (Samsung uses the FF button on some models.)
After that, it's not good news. If other players work, that may be the cheap fix.
My Blu-ray player no longer works via hdmi to the TV it's been connected to for the past 3 yrs after we lost power one day. The Blu-ray player works fine with any other TV via hdmi just not the original tv. I have replaced hdmi cables and still nothing I have introduced other Blu-ray players to the TV and it works just fine. I have even tried a hdmi switch and it won't work. Only seems to work with rca cables but the picture isn't as clear. I have reset both tv and Blu-ray player to factory settings and nothing. Any ideas what I can do to fix this problem.
