Hello I have a Samsung un50mu630d 50in tv I bought from Costco Jan 2018, today the power light was blinking red non-stop - there's nothing wrong with the TV image but when I try to use an app to watch TV the TV will continue to turn on and off. I've reset the TV in multiple ways and nothing has helped so far. Is there anything else I can do or do I have to have someone come fix this??

I would love to assist you with this. 

 

Is the unit pulled into a surge protector? If so, try plugging the unit directly into the wall outlet.

 

Is your standby light on, off, or flashing?

 

If the standby light is on:

  • It is normal for the standby light to be lit when the TV is turned off (as long as it is plugged in and receiving power). But if the TV still won't turn on when you try, the only thing left to rule out is the remote.

First, try turning on the TV without the remote. (The Power button's location varies depending on your TV's model. If you are not sure where it is located, see your user manual.)

    • If the TV turns on this way but not with your remote, troubleshoot the remote.
    • If your TV still will not turn on, service is required. 

If the standby light is off:

  • Without using the remote, press any button on your TV except Power.
    • If anything appears on the screen when you interact with the controls, this confirms your TV is on. You can continue troubleshooting by going to the next step.
  • Unplug the TV for 30 seconds, and then plug it into a working outlet.
    • If the standby light comes on (and doesn't flash or blink), your TV is receiving power and will probably turn on now just fine. This means there is an issue with the original outlet, or the surge protector if you were using one. If it still doesn't turn on even though the standby light is now on, continue troubleshooting in the section for TV won't turn on, and standby light is on.
    • If the standby light comes on but flashes or blinks, or if the standby light still doesn't come on, service is required

If the standby light is flashing:

  • Surge protectors may eventually wear out and stop providing the necessary voltage for your TV. If you're using one, make sure that you rule this out before you set up service for a flashing standby light.

If the unit is turning on and off by itself try the following:

 

  • 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. 
  • Unplug the TV for 30 seconds.
    • Unplug the TV from the wall outlet or surge protector for 30 seconds, and then plug it back in.
  • 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.
  • Disable the Power On with Mobile option.
    • TVs that 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 above troubleshooting steps didn't help, here are some service options:

- 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 processed.

- If you're within the one year warranty, you can Private message one of our moderators to have service processed. http://bit.ly/33ipYnO

- If you're OUT of warranty, you the following link to locate a service center in your area by using the link below
