Complete manual included schematics layouts and alignment procedure, clear to read and magnify, extremely pleased with manual and owner manual . com's service
Thank you, this is a rare document. Few others have it, but they charge way more for a download.
Great deal (even if you have to wait a few hours to get it).
The purchased manual is an scan of the original Panasonic paper-based Service Manual. Unfortunately the contrast is not perfect, but I am satisfied anyway!
