I found this service manual to be complete in every detail except for troubleshooting charts. It would be helpful if it had a set of troubleshooting charts; however it is a very good manual otherwise and for the price it is very well worth it.
 ;
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 high quality scan of the original Philips paper-based Service Manual. I am very satisfied!
