2006 mazda tribute radio problem HELPPP
 

I brought my car in to have the rear brake hoses replaced. After I picked up my car, I noticed the clock was wrong. Upon pushing the clock button to change the time, the radio shut off for about 5-10 seconds, and then came back on with the "HELLO" screen. I then began to realize every button was causing this to happen, including the power button. So the power button won't even shut off the radio permanently, every button just "resets" the radio. I am extremely confused and this is very frustrating.
