This will help you find the Sams Photofact service literature for your TV.
Then, call your local / neighboring public libraries, and ask if they have it;
a good place to start is at the Reference desk.
You may be able to check it out, or at least make Xeroxes of the relevant pages.
Almost free, save for gas to drive there or copying fees. You can often find genuine RCA Service lit on ePay
as well. Look hard and "ask seller a question" as required.
