All hdmi connections not working on a samsung ue40c8000 every thing else seems to be ok. done a factory reset does this sound like a new board costly? regards. Norman

The tv Samsung refurbish main tv Turner signal board will set u back like $120-130 bucks + shipping and handleling and u must have to have some basic mechanicals skills like take things aparts and putting it back togther again to fixed this tv just for the used of those HDMI hubs ports again.My questions to u is?Does ur tv used 100% must require those useages of those HDMI hubs ports.Not just used the Samsung tv as is.My Samsung tv have the same problems.I just work around it by skipping all the useages of all those HDMI ports hubs of the tv altogther.Most poeple just used about like 3 HDMI ports hubs for like a HD cable box or DVR cable box and a PS3,WII games systems or Blu Ray DVD player.All these devices can go through hook up for like a RCA component cables hook up like AV1,AV2 and last one a HD hookup by a RCA component cable just add 2 more components wires like a green and purple connections or just buy a set of RCA components cable that design for a HD output.I did that,must more reliable set up too.Because those RCA components cables set up have more plastics in it connections for insulation holes for little shorts and sparks better than those HDMI ports hubs and HDMI cables barely help and the plastic for insulation is a joke almost non exiten.Those all dam HDMI ports hubs are all link into one path way on the circuit board,one dies or got shorted all dies and get shorted out.
