Hi, I purchased this radio used a few days ago & it worked fine till last night. I put a batter in the vehicle I purchased it with then turned the radio on. It powered on & to my surprise, it said “Sensor by Nomadio” which it hadn’t done b4. I then powered on the car & it said something else & I missed what it said as I had music going, I turned the radio off then back on again, but it did not power on this time & has not powered on since. I took it apart & looked at the diode that you had shown the burnt out in yours & it looks fine. I didn’t see anything else that could have been burned out. I put fresh AA in it & tried again to no avail. Any thought on what it could be? What I missed. Kinda pissed off as I used this thing twice & it’s already dead.
