Tv turned off and won't turn back on

I have a Q900 8k TV(model#QN55Q900RBFXZA),

I was watching TV one day and it suddenly turned off then I tried to turn it back on and it wouldn't. The stand by light is on so I'm not sure if its due to bad cable(invisible cable),the OC box or possibly the TV. I've tried unplugging it from the wall waiting then plugging it back in, and tried turning the tv on with and without the remote both dont work. Has this happened to anyone or does anyone have any suggestions or any advice?

Re: Tv turned off and won't turn back on

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.

This type of issue will need to be addressed by having the unit serviced. If the unit is in/out of warranty you can use the following link to find a list of service centers near you that can do the repair:
