I recently acquired a 75" Hisense 4K UHD HDR Smart TV that just turned 2 yrs. old but stopped working 6 months ago! The tv powers on, has sound, but no picture. The red power-indicator light flashes a few times when turned on. When I put the flashlight up to the screen, there ARE images there. Best Buy's Geek Squad did an in-home diagnosis of a bad Power Board; however, I just replaced it with 1 from Shopjimmy and the exact same problem persists, so the Power Board obviously wasn't the issue (way to go, Geek Squad!). I'd surely be grateful for any suggestions anyone can offer.

The leds are wired in series
One burned out stops them all
If you can see the picture it is almost certainly the leds
Isolate the burned out strip and replace it
