How can i mend my awa model bdu125k dvd/cd player?

Hi. I have a AWA DVD/ CD PLAYER Model BDU125K which has some serious problems. The green power light comes on but that's it. No radio, no sound and no DVD/CD playback. It was working fine but has now got some sort malfunction. I see the current CD I have in it now is progressing through the different songs but no sound at all!! I really would appreciate some help!!
