CLD97 PIONEER Service Manual by Philip Bunting;

Inventory (Stock): a rather extensive list of service manuals, which are hard to find, especially 15+ yrs old. Pricing: very reasonable. Delivery/Response: Very Prompt delivery of product: Placed order and received download access within 1.5hrs. Service Manual: a rather complete OEM service manual (15.5MB pdf file size). Scan quality was very good, accept for a few circuit board diagrams that were dark; Zooming, however, clarified the image. Has the required information for servicing the LD Player.
