Hi , i`m Jack

If you just want the service manuals that is no problem but they won`t help you much (if at all) with the RS-232 programming

As you probably already know you will need a null modem cable for this

All the documents that can be found on this are provided with specific software and/or hardware

If you still want the 2 service manuals i could give you that as well but unless your tv is broken it wont help at all

click the link below and if that link opens a login window popup then just close it with the upper corner X or the "no thanks . continue to view"
The manual is behind that , wait for it to open and use the DOWNLOAD button .
