Hi @Lilahh2g,
Welcome to the Roku Community!
We understand that you are getting lines on the screen of your JVC Roku TV.
Have you tried contacting JVC support yet to inquire further? I'd suggest starting there to see what options or suggestions they can provide. Each Roku TV manufacturer provides direct support and warranty services for their products running the Roku OS.
You can reach them here: http://www.us.jvc.com/support/ | https://jvcsmart.com/pages/support or call at 1-888-582-8870
Please keep us posted from there if you need additional help.
Best regards,
Mary
