i have a jvc RX-ES1SL system and the main amp at the bottiom will not turn on. so i opened it up and a fuse was blown, i then replaced the fuse and it just blew as soon as power was put into the machine ( not even turned on at the front). it is the fuse at the back where the power comes in (the one nearest the red coil). i have no idea where to start. but i cant seem to find a circuit diagram anywhere. i dont know it it is something simple or if it is a comoponent that has blown. please may you e-mail me wither a circuit diagram or, if you have come across this before then please e-mail me what to do as i can not aford a new one. thankyou. josh e-maill me on mini_mad_2006@hotmail.co.uk
