This depends on whether you have digital cable box or not. If you have a Digi Cable Box look for the red/white RCA output and connect this via RCA cable to the Red/White Audio input on your surround.

If just Basic Cable look for a red/white audio output on the back of your televison. connect this to the Red/white in on your surround. Could be called tv in or auxillary.

I had one that had a black screen and fixed the problem by repairing the inverter. When I opened the unit I looked at the capacitors on the inverter board and found them swollen. I looked at the bottom of the board and found that the fuse had opened up. The caps were a cheap quality low temp variety 150uF at 25V I replaced them with 330uF 25 volt 105C caps. I then replaced the 2.5A surface mount fuse with an axial 2.5A pico fuse and the TV worked beautifully.

If there is still about ? 24. Volts coming from the Power Board when it goes dark, it will be the Inverter board that needs replacing. If not, it is the Power Board that needs replacing. The Voltages should be written next to the sockets & plugs on the Power Board.
