    Samsung UN46D6000SF LED Backlight

    This was given to me and I have no history at all

    When first plugged in, the standby light comes on and blinks 5 times and goes out
    I can see the back light come on fairly bright through the holes in the back panel
    then go out and back on dimmer and stay on but the standby light goes out
    I can turn it off with either console or remote and back on where it will repeat the above

    I have no OSD just a black screen so I can't hook it up to a signal but tried to turn the sound wide open so as to hear a noise but hear nothing

    I'm thinking it should show the Menu (OSD) with no source hooked to it

    I replaced both Main and Power Supply board with no change

    If I unhook power line from PS to Main, the back light stays on much brighter and looking through all the holes in the back, seem to be equally bright

    Could my problem be the TCON board

    Well, I replaced the TCON board and no go

    I have no picture, or sound. the standby just blinks 4 times and nothing else

    At the plug going to the LEDs, I have on the 4 wires 62-149-149- 267 volts to ground, is that normal

      This is strange. Your backlights are behaving as expected. Bad LVDS cable ?

        no, he would still have sound.
        probably a missing voltage somewhere.

          I had a D series TV(3D smart) a while back and I know that this series suffers from bad panels.
          Try removing the ribbon cables going to the panel, one at a time. I'm suspecting a shorted panel.
          Mine it was like that, when one of them it was removed on the other half screen I had image.
          I won't be picking up D series TVs anymore, I will stay away from them, they have bad panels.

                Please show us the pictures of the whole back side of the TV so we can see all the boards and how they are connected together, then good straight shot pictures of the power supply board.

                  Ok thanks I will do that, the tv is at my inlaws house and should be going soon to look at it and will post pics. I wonder why Samsung does not provide us with a code list as to what the specific blinks means , as I'm sure they all mean something?

                    They have no meaning for Samsung.

                      This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors

                      I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using

                      I am comparing them to a brand new one that I installed

                      The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well

                      I going to let it run for several days before I remount back on the wall next to the...

                      Problem

                      This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                      Samsung QLED QE65Q7FNAT only standby light

                      TV: Samsung QLED QE65Q7FNAT
                      PSU: BN4400940A
                      MB: BN94-12832K

                      I got the tv in spring 2024. At that time it started, then ran 60 sec and poweroff. Seemed like reboot issue. I didn't have time and room to check it in summer so I plugged it in and now the standby light is on. I press button on remote, standby light goes off and tries to start?. No picture or backlight on LCD. I thought about removing diodes like in this thread: https://www.badcaps.net/forum/troubl...sung-qled-q60r...

                      Samsung UE60KS7000 No Standby Light
                      by marcinq
                      Hello,

                      I've got a problem with a Samsung UE60KS7000 that was given to me and said that there was a problem with the One Connect box but as I understand the TV should turn on even with the One Connect box disconnected (which it doesn't). There is no stand by light.

                      I've disconnected the Main Board from the PSU and when connecting to mains the backlight turns on which suggests the PSU might be ok. I've measured the voltages out of the PSU and they seem reasonable (like the labels say). The main board has no obvious burns, there are no shorts on the power rails anywhere....
