Hi there Just joined a few weeks back - had my Lexus IS200SE for about 2 years now - best car I have ver owned - no issues apart from lost all sound to my speakers - seen a few posts saying maybe the amp gone - was wondering if anyone had a diagram of the fuse bos to see if it is just a fuse - the stereo is working there is just no sound. Help me please?

I have a 2001 Lexus IS200 SE - on my way to work this morning all of a sudden I lost all sound from my stereo - please help with a solution - all power to stereo is still working - even with volume control right up there is no sound - when I use the left hand dial to alter the bass/treble etc. it does not display on the stereo either - Is the amp on a separate fuse - if so then where is the fuse box.
