JVC Roku with sound, but screens black

So for some reason my tv has no picture, but you can still hear clicking when you use the remote. My JVC has Roku built into my TV so I can’t move it different HDMI port if I could. I’ve tried all sorts of reboot/restart codes & techniques & nothing has worked. Any tips or useful suggestions? Kinda need it’s fixed ASAP!

Re: JVC Roku with sound, but screens black

Same problem with a 43 inch JVC Roku TV purchased xmas 2019.  In the middle of a show on Hulu, pause to go to the kitchen.  Come back with sound and no picture.  Did a hard reset with the remote and on the reset button on the TV.  Also tried leaving it unplugged for an hour.  Nothing.  Walmart no help.  JVC no help (they say it's China's problem and they just lease their name out).  Searched online and it seems Roku has no answers either.  Sweet. Money well spent.
