Re: OM5P-AP radio failing... no lights

I took apart our radio that wasn't powering on to see if there was anything I could noticeably see as a problem. There are only two screws under the front foam feet. The screws don't need to come all the way out just loosened then the top is able to pop off easily. There wasn't any heavy swarf or any noticeable burnt components. There are three antennas in the radio one along the front and two along the left side when looking at from the rear.

I had to cut/pry some adhesive off to remove one of the antenna connectors to get to the bottom of the board pair (their are two boards, one main board and daughter board in a slot). Once I did this I was going to check the voltage at the input barrel but when I plugged it in the light just came back on. Not sure what happened but it doesn't seem like dead radios are dead forever which is a good sign. I still worry about using this one on our competition robot.

In summary opened it up and after plugging it in it started working again without me intentionally fixing anything.
