Saving Panasonic Omnivision 13

Product Name: Saving Panasonic Omnivision 13
Great used condition viBrahe retro Panasonic Omnivision 13" White CRT VHS TV VCR combo PV-M1379W with cable. I didn't have an antenna to test the channels, but the VCR works great. All the buttons (fast forward, etc) are tested and working. I unfortunately can't figure out how to take saving a picture of the TV screen, with and without a tape in, to show the screen is clear and working, without dark lines appearing. They only appear in photos - not on the actual TV. The screen works great with a tape in and when nothing is in its clear blue. Cosmetically, the TV has scuffs, stains, and general signs of age and use. I've tried to take photos of the main spots. This doesn't come with a remote control.
