1 Backlights are working but screen is black...any ideas?
Hisense 65R7050e1
My tv originally was blinking on the Hisense screen. I troubleshooted from replacing the boards to just now replacing the backlights. Now the back lights are all working and the screen is black. I can hear audio (just general click noises) when turning up the volume on the remote..and a slight power up and down audio noise (that Ive never heard before) when I push the power button. So no Hisense screen...just black. Any ideas? Thank you

Hi, so complete story. Tv started blinking on from the introductory Hisense screen to black. The left part of the screen was darker than the rest. I did some research, and was told it was the main board (Hisense 259415 243905 Main Board 65R7050E1) . Ordered it from Shop Jimmy. It came, I tried it. Same problem. Returned it and ordered the power supply board (Hisense 242585 Power Supply for 65H6570F also compatible with my 65R7050E1) It came, swapped it. Didnt work, same Blinking issue. Returned the board. Was told on a message board that it was the Back Lights, a frequent problem with this Tv....and apparently so because shop Jimmy was out. Waited a couple weeks and ordered when they were in stock. Replaced Back lights. Put Tv back together, and lights come on in full force but TV is black. Checked connections, pulled Tv apart, checked LED strip connections. All backlights work, screen is black. There is one last board that I havent swapped out... Tcon board. All the ribbon strips are intact. TY
