Check your remote for a "PIP" button or read the instructions; most PIP TVs have a section devoted to its operation.;
, PIP works only when more than one source is connected to the TV (i.e. cable & satellite, cable & "over the air" -- free, using set-top antenna -- channels, etc.).
 With most TVs, pressing the "Input" or "Source" button on the remote will select from the various items you have plugged into the TV (again, satellite, cable, VCR).

Make sure your TV has it!,
Find the source(s)!,
Engage the PIP by pressing the "PIP" button; a small box should appear in one corner of the screen.
When you're dizzy from watching two things at once, press PIP once again and the smaller box should go away.
