Critical Parts Lookup Information
• Always look for a “Version Number” on all products. The version number, where applicable, is printed on the model serial number tag.
• Always get the Serial Number on all products. During the manufacturing process, parts can be substituted. These changes are tracked by serial number.
Product Example
On TV products, the model serial number tag is located on the right hand side of the cabinet.
