Looking to connect audio system to the Sony tv

Solution
It seems that SPA3800b has analogue audio input only (2xRCA). There are no pictures nor detailed manual, so I can't tell much more. And if that's the cas, @Jay32367 way to do it should work - 3.5mm-to-RCA cable from TV' headphone jack to Phillips' audio in.
