    Samsung UN46C5000QF (No Picture - Sound Working - Backlight Working)

    Hi Guys,

    Hope you can help with my issue, I can use a meter and soldiering is not an issue.

    I have a Samsung UN46C5000QF that has sound and no picture. I have attached a picture of the T Con board and the backlight working. If you need anymore pictures let me know

    I turned the TV off this morning when I left for work this morning and it was working fine & when I got home this afternoon I turned it on like normal and it makes the Samsung Boot Noise and i can hear the sound from the cable box or the xbox360. I can't see anything but i can turn it up and switch inputs.

          The fuse @ FP1 is good.

          I have attached a few more pics for you.


          Please help if you have anymore ideas, which board do you think is causing the issue?

              I also noticed that there is no red light in the optical port when tv is powered on.

              Edit: The red light comes on for 1 second at boot.


              Not sure if this matters or not, just noticed that on my other tv's the red light stays on.


              Edit 2: I found the service manual for this TV.

                  Unplug T-con and see if red light stays on.

                      It does the same thing with t-con unplugged, only comes on for 1 second at boot.

                          You're getting sound continuously, I missed that. I'd swap the T-con, if not, it may be a panel problem. Unlikely, though not impossible, to be a main board issue.

                                  Swap t-con in first; if that fails, then swap in the main board, if it works, you know t-con was the only problem.

                                      Hi all

                                      I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.



                                      Symptom:
                                      No picture no sound.
                                      When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
                                      No sound at all.



                                      What I tried:
                                      1. I tried unplugging the left or right ribbon...

                                      This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

                                      Problem
                                      TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

                                      As title states, sound but no picture. I have done all of the rudimentary troubleshooting steps- flashlight test no lights visable. Checked Source and it is correct. Tried different, verified good HDMI cable, swapped satellite receiver boxes etc and no luck. I see lots of kits with replacement boards, but before I start throwing parts at it I'd like to know if anyone has suggestions. The brown power board has a couple of spots that are suspect. They are a darker brown circular color. Not sure if that is just from normal use or if something may be burnt. Not sure if a suspect power board is capable...

                                      Hi I have a samsung LN52B550K1F LCD TV. There is no backlight but I can see a picture under a flash light. The sound is playing as normal. I have attached the pictures of the boards.

                                      With my laptop connected to HDMI4 port, I tested the voltages of the connectors:

                                      by Porkchop1113
                                      Hello all. I have a Samsung 48” tv that has no picture or sound. Looking for some assistance on diagnosing my problem so that I can repair it.
                                      The facts:
                                      Random day the screen went black. I had sound for a couple minutes, then it went out also.
                                      The red standby light comes on. But still nothing powers up.
                                      *So my main question is where do I go from here? I'm familiar with testing with a multimeter. Maybe someone can point me in the right direction for testing or repairs. I've checked a couple websites like shopjimmy and electro-parts, so the boards in the tv are available....
