Can someone help?. Recently brought a AV9000 & master panel, but found the VCR and cassette player are not working, the VCR will rewind and forward wind but will not play, the cassette player will not do anything although it does make a clicking noise if you press play or forward/ rewind, every thing seems to be working perfectly. I would be grateful for any imput on this subject, i have been trying to find a service manual, these seem hard to come by.
