    Samsung UN55J6200. Quick question before deciding to mess with this one or not.

    I picked up a Samsung UN55J6200 that stopped working after a nearby lightning strike yesterday. It's a relatively new tv, so it might be worth digging into but I have a backlog of about half a dozen to work on for friends and neighbors, so I'm trying to decide if I want to mess with this one or not.

    -When plugged in, the red standby light comes on, as normal.

    -Press power on either the hard key or remote, results in the red standby light going out. About a second later, the backlights flash the screen in one quick burst and go out. Then the red standby light comes back on.

    -There is no flash code. Just red light, no red light, backlight flash, and back to red light.

    I have a feeling that the problem is a bad backlight, which I have no motivation to tackle.

    Has anyone seen this particular behavior because of anything relatively plug n play, i.e. bad caps, definite failure in an individual board, etc.?

    If there is a possibility that this will be a reasonably easy fix, I will abide by the forum rules and take detailed pics of all the internals. I'd just like to pre-screen it, if possible, before getting to deep into a repair I don't have the time to tackle.

    Thanks in advance.

      Unplug the main board from the PSU, then plug the tv into mains power. The backlights should turn on. If it does, your problem is the main board.

          As capleaker says.
          You are thinking way to hard and you already gave the answer yourself. " After lightningstrike the tv stopped working".

          Lightning usually goes via coax/hdmi into the mainboard so unplug mainboard from the P board and turn on the tv. Backlight turning on then you got a bad mainboard.

              The backlights come on when the main is unplugged from the power supply. Are there any repair options for the main or do I have to just buy a new one?

              Thanks for the help.

                  In this case, replace the main board... you'll be chasing and troubleshooting a lot after a set got hit by lightning.

                      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 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....

                      LED TV Samsung The Frame 55 inch QE55LS03RAU Standby Light only
                      by ChristianBr01
                      Hello everyone,
                      I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
                      The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
                      What I already found is that the 12.8V are not an the connector to the main board connector to the power...
