My screen went black and have no sound. I don’t have the remote so only thing I can do is hit the buttons on the TV. I replaced the T-Board and still didn’t fix the problem. Its a 70 inch Vizio model #E701I-A3B. Can someone help me?
Is this a good question?

@jmfowl since you have no audio I would not yet have replaced the t-con board. you will have to remove the back from your TV and take a look at the power board and main board. You need to check the voltages going from the power board to the main board. If the voltages are correct your issue could probably be the main board. Post some good pictures of your boards and interconnect cables with your question so that we can see what you see. Adding images to an existing question
