LG Dms 5620 mini hifi stereo?

Question

I Moved my radio and by accident pressed buttons.

I have seemed to lock my hifi, it doesn't open the 3 disc tray, neither does sou damage come out the speakers. 

AL speakers are correctly plugged in, tested on another DVD player and NO discs are in or jammed... 

When I put it on normal radio stations no sou do out the speakers.   

All buttons are work and remote too. 

It seems like there is a lock on the radio and I have tried to reset it by holding in 0 on the remote and stop button for several seconds. 

Any help is much appreciated. 

Thank you 

Update:

There is no sound out the speakers, sorry, not the sou damage.

There has been no damage to the radio at all

Can a doctor diagnose an internal disease without examining the person who has it?    

You need in-person help from someone capable of dealing with this kind of thing.
