Hi all,
Trying to fix a car radio (Grundig beta 5) for a local lad who wants it for his car. When you press the soft power button, some jumbled segments appear on the display, then it shuts down.
I'm wondering if the microcontroller is not getting a reset signal. It's labelled OE57S. How do I find the reset pin to check this?
Also, any other troubleshooting tips would be very helpful!
Many thanks
