Problem with radio and taillights

So today I just installed my new led bar lights I received from ddm tuning, next thing I know my radio does not work. So I have power leading to the unit and the radio always worked perfectly before I installed the lights but I can't figure out the problem. I might have touched the cd changer a little bit meaning I unscrewed two screws and wiggled it around a little and i accidentally dropped a screw from the light beside the battery but still can not figure out what the problem is because the radio shows power but when I press the power button for the fm, it does not show anything or whenever I click the audio button. Let me know what you guys think.

Recheck you have all the plugs in OK. Spray them with contact cleaner. I think you touched it harder than you recall.

If the botton for on & off not show tha orange light under when u push,but cassette player sound like working that means is the radio fuse.where is it located? open the trunk,the left side opposite to the battery side,there are cd case,telephone component others staff ,u have to take those out & behind the cover u will see a part belong to the radio ease take it out & test the fuse.Easy to change.Good luck.
