I have for the past month or so my q90r (QN65Q90RAFXZA) has been flashing on the top half of the screen. I have gone all of the suggested procedures to troubleshoot other than a complete reboot. I am trying to figure out which internal board it would be so I can fix it myself.
We appreciate you sharing this concern with us. If you have already attempted the troubleshooting steps for the TV (shown below). Then the next step would probably be a service repair. We can't provide any details about replacing the internal board. However, if you need information on parts, you can visit Samsung.com for a service manual. http://www.samsung.com/us/support/troubleshoot/TSG10002218/
If you would like us to set up the service; Please send us a private message to the link here.
