Page 1 of Bush 2004 - Help needed....PLEASE!!

A mate of mine has this system and it has worked fine for the last year. It eventually stopped playing CDs so he got it replaced. Since then every time he switches on his TV it goes directly to AV1 for about 10 minutes and then the TV sitches to `normal` mode. The fast forward function is knackered too - it won`t stop when activated. When he replaced the unit he didn`t change any of the wiring. Is the unit knackered or is it a set-up issue?

BTW, he didn`t receive a manual so difficult to ascertain!
