<_< i have a 2004 gs430 the stearo has been working perfect . i turned it of and when i turned it back on there was no sound. the radoi seems to be working it searshs no stations reads the cd but still no sound. when i went to the screen to set the balance and base the screen shows no lines of when the currant things are set. i am thinking it has to be the amp . i check the fuse good i check the contacks at the amp but no dif. the car only has 35,000 miles on it could the amp just go out like that or am i missing somthing thanks all ray
