Brand new UE70TU7 100K - 70” 4K UHDTV - worked for 4 hours, then turned itself off - now just getting a blinking red standby light and black screen on/off issue - poor quality products, never buy another one - may as well throw money in the bin - that’s all these TVs are worth (this is the 2nd samsung tv in a month - the last one was delivered with a damaged screen)
@Rob369 Sorry you have has a bad experience, however whist some customers indeed have issues there are satisfied Samsung owners out there though that may not be of much comfort. Whilst it may be the screen or the board I suggest you try the following troubleshooting:
Ensure power cable is secure and If you have not done so already can you try another socket, just to rule out any issue there. If not the problem assuming you cannot do factory reset, disconnect all devices and switch off Tv at the mains before trying again.
If to no avail then I would suggest contacting Samsung Support. https://www.samsung.com/uk/support/contact/
