TV pixels suddenly glitch then black spots creep out and crash

[YiDai]

 

Model: UN58TU7000F

I tried:

- Unplugged, waiting for several minutes then plugging it back.

- Factory reset

- Soft reset

-Software updates

All did not work. 

My TV works completely fine for around 5 minutes with absolute no issue before the pixels freeze and glitch and a black spot creeps up (as shown in the picture) then immediately black screens. After that, the TV blinks multiple times for like 5 minutes then turns on again just to repeat the entire process.

This started happening a few days ago but only once in a couple of days. Now it is every 5 minutes or so. The TV is not damaged at all and bought new 2 years ago. Appreciate any help.

Hi there! Thank you for reaching out. I know how aggravating this is and am happy to help! Have you checked the power cable for any damage? Is the TV plugged into a wall outlet or a surge protector? If it's plugged into a surge protector, try plugging it into a wall outlet and see if that helps. If not, the TV will need to be serviced.
