Samsung UN55C7000 purchased at Future shop brand new. Have been using it for about a week now and I notice HDMI port 3 does not work.
I have a Bell Expresvu HD receiver connected via HDMI cable to HDMI port 2 on the TV and picture and audio works flawlessly. I also have a Sonicview 8000 HD free to air receiver connected via HDMI to HDMI port 4 on the TV, audio and picture works flawlessly.
I tested both receivers on HDMI 1,2,4 on the TV and both receivers audio and picture works flawlessly on those HDMI ports.. When I connect the Sonicview 8000 to HDMI port 3 I get no signal. When I connect the Bell Expresvu receiver to HDMI 3 I get no audio but I get picture however the picture has a lot of static and red faint streaks/lines that flash consistently right across the screen and if you look up closely you see a lot red static in behind the picture... I tried to turn the TV off unplugged every cable from the TV let is sit for 30 min. plugged it all back in, problem still there. I tried the reset on the remote hold down the "exit" button on the remote to reset the TV, problem still there. I updated the firm ware on the TV when I first go it, firmware is up to date. HDMI cables I believe are 1.3 however it does not say 1.3 on them, purchased them about 4-5 years ago though. I did a test, I have a new 50' HDMI 1.4 cable that I just purchased for another project some where else. I connected one end of the 50' HDMI 1.4 cable to the Bell Expresvu receiver and the other end to HDMI 3 port on the TV and WORKS perfectly ! Audio and picture is perfect !
My other HDMI cables on the receivers work perfectly on HDMI ports 1,2,4 so that tells me the cables are fine.. but do not work on HDMI port3.. so that tells me it's a problem with the TV.. but when I use the HDMI 4.1 cable.. port 3 works perfectly ! ?????? I am so confused.! Is it a problem with the TV? Problem with the HDMI port 3? or a problem with my HDMI cables? Does not add up. I don't know what to do. Any one have any ideas, highly appreciate it. Thank you.
