    Samsung UE60KS7000 No Standby Light

    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. Unfortunately this main board doesn't seem to be easily obtainable in the UK so I'm hoping to repair the original one. It seems to be one of those with integrated TCON.

    TV Model: UE60KS7000
    Panel PN: Samsung CY-QK060FLSV1H
    Main Board PN: BN41-02504 / BN94-10757K

    I've read the three easily accessible memories on the main board and their contents is attached. Unfortunately I can't read the eMMC easily. Could someone please check if the contents seems reasonable and perhaps someone has a bin file for the memories that I could try if this indeed is a problem with the firmware.

    I've attached photos of the main board and panel PN sticker.

    Any ideas are welcome

    Thank you

      I didn't see any problems in your dumps, check the voltage and resistance on the inductors relative to ground...Click image for larger version Name: JAZZ_M_USIT1.jpg Views: 21 Size: 484.1 KB ID: 3646027​

          Samsung QLED QE65Q7FNAT only standby light
          by Kaar3l
          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 UN70NU6070F Standby Light flashes twice
          by Nicktronic
          Hey Everyone,

          So I've got this Samsung and the reported issue is that when powered on the backlight comes on, but no picture, no sound, it will flicker, the standby light will flash red twice and repeat the whole process...each loop lasts about 15 seconds.

          I've googled the issue and understand it is likely a panel/driver board issue, but was hoping the "tape method" could be successful. Before I did that though, I disconnected the left LVDS cable and powered the TV on. This time I got sound, no picture and the two blink standby light stopped. Did the same...

          Samsung ue55tu7170u not turn on and no standby led main bn9650990e
          by PNI E.
          Hi guys, I’m back here my friend give me her tv, that doesn’t turn on and no standby red led. When u plug in the cord the red led of one two second is on, then turn off. If you push the power button or the remote the red led blinks but nothing happen. I give u some photo with voltage, don’t look the fuse….because I blow it for mistake nd I dint have the right replace so I just put it for test the tv. The standby voltage should be 11,88 volt on the diode, but I have 13 volts. I put in the photo the different volts I test and there are someone negative…I don’t know if it s normal. On...

          Samsung TV`s UE32J5500AK and UE48H6400AK Red Standby Light - No Picture/Sound
          by slimsoul
          Hi, I'm new here and looking for some advice on how to diagnose an issue i have with 2 samsung TVs.

          I have a UE32J5500AK and a UE48H6400AK both with the same issue of red light but nothing happening on the screen, the red light responds to remote or button press by flashing once but stays red. I have searched forums but most turn up a blinking red light.

          I have tried replaceing the power board on the UE32J5500AK last year but this resulted in the same outcome.
          The UE48H6400AK recently developed some small bright areas on the screen, then last week would not power...

          No Standby Light on Samsung UN65MU6300FXZA with Mainboard BN94-12440E
          by Michael Long
          I had a Dead Samsung UN65MU6300FXZA with Mainboard BN94-12440E
          Dead / No Power / No Standby Light results after power company had three
          consecutive power outages on/off/on/off/on/off after which TV was rendered unresponsive.

          After exploring the issue found Mainboard was the fault. Then with research on this site determined IC1604 was the suspect. The IC1604 is a surface mounted device (SMD) EEPROM, Winbond Model 25Q40CLSIP. A read on this EEPROM came back with all FF FF FF FF FF in all registers blank and empty of data. I had a spare mainboard with intact IC1604 and utilized...
