KS800D Turns Off or Locks Up crashing out

I have a five year old Samsung UN65KS800D that seems to crash out. Sometimes the whole thing just turns off, no warning, nothing on screen, just instant to black. Sometimes it crashes out (screen black) and the Samsung logo on lower front bezel that's normally solid lit will stay on but be rapidly flashing on/off endlessly. Each time I have to remove power cable, plug back in, and it comes back to life. Seems to matter if the TVs been on a while. Can get from 30mins to 2 hours. Once it starts, it crashes out much sooner (just a few minutes), we have to leave it for a fair while. Seems like once some chip gets hot, or power supply gets hot, it flakes out. Checked that its on the latest firmware. Power cable is tight. Changed remote control batteries.  Any suggestions?

Here is a link to a video I shot of it when its **bleep**g out https://www.dropbox.com/s/tmhm21pk3ozrwtg/2021-11-06%2015.18.32.mp4?dl=0

Hello, I understand how this can be a cause for concern with your TV having these issues have you tried the following below? 

 

By default, some HDMI devices are set to turn the TV on when they turn on. This feature is Anynet+, also known as HDMI-CEC, and allows you to control both devices with your TV remote. If you want to turn on your devices separately, you can turn off Anynet+ in Settings > General > External Device Manager, but you will no longer be able to use your TV remote for both devices.

  1. Unplug the TV for 30 seconds.

    Unplug the TV from the wall outlet or surge protector and leave it unplugged for 30 seconds.

  2. Inspect the power cord for damage.

    Check the power cord to see if there is any visible damage. If the power cord appears to be damaged. You can get a replacement at samsungparts.com.

    You can search for your TV model to find the exact power cord you need.

  3. Plug the TV power cord back into the wall outlet.

    If you were using a surge protector, bypass it for now and use a wall outlet.

  4. Try to update the software.

    In some cases, a software update can correct the problem. There is a risk, however. If the TV turns off during the software update, it could damage the TV. Updates can take up to 30 minutes depending on network speed, so if the TV is not turning off too frequently, try updating the software.

  5. Disable the Power On with Mobile option.

    TVs which can connect to SmartThings can be turned on using compatible devices, sometimes automatically. However, if abnormal "power on" signals are sent through the wireless network, they will trigger this function and make the TV turn on.

    If you do not want this function, navigate to Settings > General > Network > Expert Settings > Power On with Mobile, and turn the setting off.

If the troubleshooting steps did not help above then this will require service, you have a couple of options based on your warranty. 

- If your unit was recently purchased, you can check with your retailer on their return/exchange processes.
- If you have an extended warranty you can reach out to them to have service set up. 
- If you're within the one year warranty, you can Private message me or one of our moderators with your full model and serial number to have service setup
- If you're OUT of warranty, you can use this link below to find a service center in your area.
