Hi Suzi, If it's dirty video heads, here's how to clean them: Locate the video head drum, which is the biggest round thing in the unit, a large tilted aluminum cylinder. Gently rotate it by placing a finger on the top and moving it. You'll see some very small horizontal slots halfway between the top and bottom of the drum, and these are your video heads. There will be 2, 4 or 6 of them depending on your machine. Poke a finger through a white T shirt (or any tightly woven cotton fabric), then dip it in household alcohol. VERY GENTLY, wipe the heads (slots) about 5 or 6 times, then check the T shirt to see if you removed any dirt. Any noticeable dirt will affect your playback quality. After doing this, check the VCR and see if your picture is back. If not, it's something else and would take a technician to repair. You can try to process a few more times just for fun, then scrap the machine if you don't get results. . . .
