Hisense tv picture went black but still has sound

"@jhammer358

you need to check your main board and your power board. First make sure that the power board supplies proper voltages to the main board. Then check the LED connector and see what the voltages are on it. If you have no power to the LED connectors it is your main board not enabling the backlight. If you have power to the LED connector but no backlight, it’s your Backlight LED arrays. Post some images of all of your your boards so we can see what you see

"Take a flashlight and shine it on the screen. If you can still see the picture, your backlights are not coming on. This could be a bad board but is more likely just a few bad LEDs. Here’s a video of the replacement process. Hope this helped!

@jhammer358 @oaktreddie i having problem same like you.. finally i reallize it is because the cable to led strip is loose or not connected(seem like connected but its not) you need to use tester to verify this.… its is series circuit 1 fail will disable all… https://slideplayer.com/slide/7391184/24...

Check the picture mode settings on each function such as TV/cable or VCR and or Netflix. Toggle through the picture mode settings such as movie, low power, sport and so forth and see if it fixes it.

Was and still having the same issue, screen goes blank randomly, - but the issue only happens while playing media on Playstation (PS4). Never with cable tv or built in streaming app. Hisense service center changed Tv motherboard as well on my complaint, but the problem persists. I think it has something to do with my PS4, or HDMI cable or HDMI licenses.
