Car Audio Problem...

I recently accidentally ran my car battery down. I charged it up using a power pack which was attached for about an hour. When I started the engine everything worked fine apart from my radio, which is only a very basic CD radio - no changer in the boot or anything fancy like that!

When I attach the fascia there is no power at all, I have checked the fuse box and nothing has blown there at all - I checked every single one, just in case but they are all intact.

I cannot think of anything else that could be the problem - could anyone suggest anything else that maybe preventing the power from getting to the radio?

Many thanks

there are fuses under the dash AND under the bonnet (hood). A few units also have a small fuse on the back of the cd player. Sometimes a fuse can look good but still measure bad, get a cheap multimeter to check them. If it's not a fuse then the CD player may be damaged. How did the battery get drained ?

Thank you for your speedy response, I left my car lights on all day, which is how the battery drained.
