    Samsung UE48H6620SV, no picture

    The backlight was not working properly, I replaced it and it works
    but when I installed the board and connected the 2 straight cables to the T-con, there is no backlight.

    I connected the satellite receiver with a scart cable and there are tons of them.
    When I disconnect one flat cable (left or right) there is a backlight, but there is no image on the display, but of course there is sound.
    When the backlight is on, the entire screen is dark blue.

    There is a voltage of 12V DC on the T-con and the fuse on the T-con is correct.
    Please help, what should I do next?

    Thank you!

      check your tcon voltages, see if they're what they should be, some testing there and plenty more videos on the subject on youtube: https://www.youtube.com/watch?v=eGMJnTlPW1Q

          make sure you put all the cables and connections back on, its easy to miss one on reassembly.

                  How do you fixed backlight, entire set of strips, single strip or single leds?

                          The backlight is still faulty, another led or more is still NG

                                  SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds

                                  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...

                                  Samsung LCD TV no picture backlight on no 12v at tcon

                                  hi
                                  i have a samsung lcd tv

                                  it powers on with sound and backlight but no picture

                                  all voltages from PS are good 12v 3.3v and 5v

                                  whats odd is that at the tcon i tested voltage across the fuse on the tcon and i get 0v

                                  i figured main board issue..so i ordered a used main board....when i put replacement main board in i still have same issue

                                  no 12v at the tcon fuse

                                  i disconnect the panel ribbon cables to rule out any panel issues and i still have no 12v at the tcon fuse

                                  the odds of having 2...

                                  Hello all,

                                  This is my first post, but long term lurker on the form learning as much as possible about these TV's. I was given this TV as due to a power outage of constant On/off of power to TV. The TV originally would just click on and off (Typical Reboot Cycle). I opened the back of the TV, and troubleshooted by taking the 96 pin LVDS off one at a time to see if I had a picture on either side. I finally fixed the reboot cycle by finding the error on the left side of the screen off connector CN 1301, and the TV would stay on. Further troubleshooting led me to the driver boards where...

                                  Samsung UE75TU7020k No picture, Standby blinks 2 times
                                  by brithepi2k
                                  My Samsung UE75TU7020k lights up fine when one of the ribbon cables are disconnected from the main board, lights stay on but not getting half a picture, I do the same with the other ribbon and put the other one in and lights stay on but not getting half a picture. The standby light flashes 2 times then reboots then it then tries to come back on again and just keeps looping until I take either one of the ribbon tables out (doesn’t matter which one I take out it stays lit when either one is out). I’ve tested the backlights but all working with none shorting out, I’ve replaced the main board...
