Saw an earlier post of same problem on update 9.2. I had no problem until just now when I updated to 9.4 and suddenly my OTA channels are blacked out. I still have a guide and signal strength meter tells me I’m getting reception. Upon troubleshooting myself, I discovered that taking out the jump drive and disconnecting pause and rewind function allowed the picture to come in. I reformatted my jump drive on my computer and jump drive was good. I reinserted into TV and went through the setups for pause and rewind and same problem. Curious note— if I pause even with black screen and then FF, I can see the progress of the FF on screen but when play resumes it goes back to black. Again...problem only occurred after updating to version 9.4.
