To connect the Coby CSMP77 Multimedia Speaker System to a Philips flat-screen TV, first, locate the audio output options on the TV, which may include a headphone jack, RCA audio out (red and white ports), or optical audio out. Use the appropriate cable: for a headphone jack, a 3.5mm aux cable; for RCA, a dual RCA to RCA cable. Plug one end into the TV's audio output and the other into the corresponding input on the speaker system. Finally, power on both devices and adjust the volume as needed.
