YAMAHA AV Receiver RX - V363 + YAMAHA 5.1 Speakers +

Hi I got a YAMAHA AV Receiver RX - V363 + YAMAHA 5.1 Speakers, speakers are fully working, but the receiver has developed a fault after which only the center channel and the sub is still working. It is not the speaker fault - just a receiver is not transmitting to the rest of the channels.. Selling all together and pickup only, close to Kilburn. Paid 400 for the whole system a year ago from RicherSounds. Grab yourself a bargain! Thanks, Mindo
