2008 Nissan sentra radio and trip/fuel display not work

[Sab213021]

I have a 2008 and the radio that is connected to trip/radio display stopped working. It is completely dead. And it made my brake lights and cluster gauge interior lights not light up. I fixed that. Two bad fuses. Than radio would not turn of when car was turned off, so I had to disconnect battery to turn off radio each day. But would not run my car battery out. Now the radio with all the other UNO that shows up on display doesn't work anymore.
Not sure if a bad fuse went out or radio is shot. I took out radio to see if there was a fuse on radio but didn't see one.
Please help. Haven't been able to listen to radio. Hope this makes somewhat sense. Thanks

So right now, what is not working? Are you getting power to the radio? does it light up at all when the car is on? Is the trip display not working also? Do you see the time and temperature on the display but not the radio stations? Are all the lights in your cluster working properly now? Did you do any electrical type work on your car before this happened? Sorry for the rash of questions but just trying to pinpoint what is working and what is not to get a better idea of the root of the problem.

No nothing is on. No power at all showing for radio and display. My cluster gauge is working and all other lights are on. What happened was, I was driving and I hit a bump and radio on display turned off than came back on. Than started making a loud noise thru the speakers when radio was on. Than the display would flicker on And off. Then 2 days later the whole radio an Everthing that would show on display stopped showing. And now no power.
Hope this makes Lil more sense.

Here's the link to the service manual for the radio. There's some good trouble-shooting tips in there, basically you want to check for power at the specific pinouts according to the diagrams - start there and see what happens.
