Find out where these capacitors are in the schematic. Sams should have the exact value next to the capacitor's symbol. Read Sams footnotes to determine if these capacitors are MF or MMF. Usually, if the value is less than 1, it's in MF. If it is more than 1, it's in MMF.

The odd part is that the Sam's that I have (I bought a PDF download from Sam's) doesn't have the schematic for the main TV Chassis, just the tuner and the remote chassis, nothing for the main TV Chassis though... at least not that I could see.

Should oughta read: "if less than .001 mf it's in mmf (micro-microfarad, aka picofarad or pf)

Microfarad or mf (sometimes written mfd) = one millionth of a farad
Micro-microfarad or mmf (sometimes written mmfd or pf) = one millionth of a mf.

Typically values below .001 mf are in mmf/mmfd/pf.
