• Hi John. We regret to read that your LG NanoCell 86 Series 4K 55 inch Class Smart UHD NanoCell TV w/ AI ThinQ® (54.6'' Diag), Model # 55SM8600PUA blacks out intermittently and the volume stops and sincerely apologize for any inconvenience. That issue will require some troubleshooting to determine if the issue is with the HDMI ports on the TV, the HDMI cable, the HD port on your Cable Set-Top Box or something else in your setup. The TV has a Limited Manufacturer's Warranty of One (1) Year fro date of purchase so you can call our Support Represemnatives at (800) 243-0000 to arrange for a service repair...^IFV
