EOS Rebel T7 Green lines in LCD monitor

[Tintype_18]

Taking some photos for a magazine. However, and never had this before, the LCD shows a green lines about one fourth from the top and bottom. Lines don't show on the viewfinder. I experimented with jpg and RAW; the lines don't show on the photos when downloaded. Camera is Canon T7 with the 18-55mm lens. Lighting is Curly Q bulbs with soft cloth covers. Camera was checked for fluorescent setting  plus verified other settings to be compatible with the setup. Three cards were formatted before use, JIC. Thought I would start here. TIA.

kvbarkley recommended to connect your camera's HDMI output to a monitor or TV to see if the green lines also show up there.  This will help determine where the issue may be.

I believe I have that cord along with a sackful of others accumulated over the years. Thanks for the correction.

BTW, no one in the family or any friends will allow me to touch their computers. I have the reverse Midas touch.

I have everything but that cord. Off to Staples!
