Hisense 40" Smart TV Full HD 1080p LED HDTV with Built in WiFi - 40K20D - Page 5 Questions & Answers
Why is my tv screen black?
Shine a flashlight into it and see if you can see a picture? If you can it is a problem with the LEDs.
It is a low budget set (despite being Smart and 4K) and not worth spending a lot of money on.
Hopefully out television expert @Larry will be along soon. Search this site for Hisense, question answered within the last two weeks.

Hisense 70H6570G does not turn on, red light blinks once after 20 seconds.
Any of the things you mentioned can cause the set to not power up, start by testing the power standby voltage, if its around 3.5 volts check the power on command from the main, if it's missing replace the main, if it looks ok (around 3.3 vdc) test the other power supply voltages, this set should be easy to troubleshoot.

Hisense tv model 75h6570g has sound but a black screen could back lights be good if power supply board is bad
I agree with you Gerald, changing the strips involves removing the panel and on a set of this size that can be an issue unless someone has the proper handling equipment and uses static precautions but taking it for repair will run more than it's worth as most places charge from $2 to $2.50 an inch for labor, total cost would be about 2/3 the cost of a new set but if a person can do it themselves the strips only run about $75.

What is the best thing to do with a75'' tv that is barely a year old but too expensive to repair
best is buy LG or Samsung TV
not china cheap junk.(alibaba_gone wrong)
gee send it back for a refund, PRONTO.
your "same hardware" is 100% false. !!!
yes it had junk LED, there, pure trash, seen many .
the TV will never be better than its parts quality.
and support and warranty and spare parts and has real service manual.
quality is NEVER FREE. (and that TV makers QA department is brain dead)<<< see that?

HiSense 55 in smart TV. Digital Antenna
This will be a main board issue, replace the board and the set will work like it's supposed to. I would take another TV and run a channel scan and be sure your antenna is picking up the channels before ordering a main

Hisense 50Q8G help finding parts
It won't be an issue finding the part but generally they don't fail on their own, not saying I've never seen it happen but of the thousands of TV's my shop repairs in a year I can count on one hand when it's just the opto. Generally, it's a part or parts on the hot side of the isolator that is bad, and it damages the opto.

Hisense 75Q8G power LED white blinking
You're correct on your theory of defective backlights, it's a common failure on this model set, replace them and the set should work again..The service code you're getting is backlight issues
