Sorry, there was a problem. Please try again later.Hello Mae. We regret to read about the issues that you are currently experiencing with your LG 75 Inch Class 4K HDR Smart LED TV w/ AI ThinQ® (74.5'' Diag), Model # 75UM6970PUB and sincerely apologize for any inconvenience. Check to make sure that the cables plugged into the ports on the back of the TV are not pressing up against the wall or check that the cables are in sound condition. If that does not resolve the issue, the TV will need to be inspected and diagnosed by a qualified service technician or an LG Authorized Service Repair Center. Please contact our Support Center at (800) 243 - 0000 for assistance in arranging a service repair or you can visit our site at https://www.lg.com/us/support/find-service-center to see if you can find an LG Authorized Service Center in your area...^IFV
