Total functional failure and no diplay
Radio display reverted from time to one digit "7".
Hit power button and there's now no display or any function at all.
When connecting or disconnecting power cord, there's a short static sound indicating power is at least getting to the unit, but then nothing.
Have replaced battery and cycled connecting and disconnecting power.
Is this repairable?
Thanks
Is this a good question?
I also have this problem.

Hello, I’ve had the same issues. I replaced both the transistor and the regulator just to be safe and got the same symptoms again. My transistor was broken when I tested it outside the board and was not located at the Q4 location like what was said. I had to figure it out my self and realized there is only one transistor in the circuit for that area of the board. researching how to troubleshoot this radio has been !&&*, and I was told some people do this repair and it works and some people do it and it does NOT work, like me. This transistor in question should be a 600mW NPN transistor, any will suffice? Maybe… I used a 2N3904 (626mW NPN) and it didn’t work. I’m anxious to get this fixed for a family friend whos possessor passed away. I need help, I’ve been an aerospace tech for a long time, so I know my practices were safe.
