65" LED TV Failure -- works for 1 minute

I am looking for some support to troubleshoot my recent TV failure. I have the Samsung UN658000FXZA Version FC04 TV (65" 8000 Series LED TV) and while watching this evening the screen faded to black and started to cycle (red LED flash then the screen would flash although dark, every 10 seconds). I have tried to reset and use an alternate power source with the same result. If I leave plugged in long enough it will cycle for a while and eventually show the normal home screen. Unfortunately, after I start a show (say Netflix) the screen fades to black after just around 1 minute .Is this enough information to diagnose whether the Power Supply or the Main Board needs to be replaced? Or could it be something in the software? The picture and sound appear normal in the brief time it displays. Please advise.

I understand how this may be frustrating and want to help? 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 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.

Unreal! This is the exact same thing that happened to my KS8000 last night. I left it unplugged over night and the same thing occurs.

I followed the steps provided and this did not solve the problem. Based on the description I provided above, can you diagnose whether it's a power supply, Main board issue, or something else? Or do you need more information to provide a specific response? Replacing either of these components is a simple process (I can perform) and would be much more cost effective than paying a service center to remove 8 screws and a couple ribbon cables to replace a board.
