• A clean, minimal product render features two black rubber belts on a white display stand. The display has “SONY REPAIR PARTS” printed on its side. Above each belt is a standing label holder. Each label includes a barcode and reads “335660301 (left) / 335674401 (right),” “BELT,” “1 PCS,” “MADE IN JAPAN,” and other serial numbers. The smaller belt is on the left, and the larger one is on the right. The image has soft lighting on a white background.
  • An exploded technical schematic diagram illustrates the mechanical components of a device (labelled as a Sony TCM-200V1 mechanism). Dozens of individual gears, plates, motors, and screws are shown separated along dashed assembly lines on a light grey background, each designated by a three- or four-digit reference number.
  • A black rubber replacement belt and a smaller matching ring shown on a light gray background, with a text label in the upper left reading 'SONY TC-K Series / TCM-200V1 Mechanism Belt Kit' and listing genuine replacement parts.
  • A top-down product photograph shows two separate, transparent plastic parts bags lying side-by-side on a plain white surface. Each bag contains a genuine Sony replacement belt and features an official white paper label stuck to the front.
