Tuners are the most difficult things to fix due to the fact you need a service manual and correcting of all trims using expensive equipment. Also it's kinda odd that both am and fm are not working. Possibly your function switch is bad. Does the stereo LED work when your on FM stereo changing stations?
I hope you find a solution. There are many different versions of that boombox, like the Sound 4008 and the Conion CRC-H58F, and unfortunately they are not very good quality. I've owned a few of them, and there is always something wrong with them.

i payd 50 eurs for that this year i'm werry happy with it!
