Sony Home Theater System (Sawley NG10)

I have to offer an HT-K170 Sony Home Theater System which is slightly faulty.It consists of an amplifier, five small speakers and a subwoofer. Unfortunatley the subwoofer will not power up. I have tested the other sterio inputs and the are working but cannot test the subwoofer output. Please note despite the Sub Woofer not working the item can still be used as a stereo amplifier. Collection from Sawley NG10. If the item is offered to you it must be collected within 24 hours of the offer.
