I don't see anything here.
Try a new jumper if your using the RF output to the tv or trying switching video sources and use RCA jacks or visa versa. If you have any stereo equipment, game consoles, RF modulators or anything else around the receiver and tv or in line between the receiver and tv, try unplugging one at a time and see if it goes away or by pass the devices in between the receiver and tv by going straight into the tv from the receiver. You never know it could be something simple, if all fails then call them, maybe an issue with the receiver or the install itself.
