Hi all,
My iPod docking station
There is a peculiar issue: the mode switches automatically. Typically, pressing the mode selection button is required to change modes (iPod, FM, etc.). However, the mode changes on its own, even without pressing the button or after removing the entire control unit. It behaves as if I'm pressing the switch button, which still functions properly.
I have tried the following:
1) Connect everything and press the mode selection button: Each click allows me to change the mode, yet it also changes automatically at the same time.
2) Disconnecting the control unit: the mode continues to change automatically. In the image, you'll notice that the connection slot on the motherboard is empty because I have disconnected the control board from it:
3) Connect the control unit: However, within the control unit, if you remove either the capacitor 104, the IR receiver, or both, you can still press the button to change the mode. This leaves me unsure about the actual purpose of these components. Additionally, the mode continues to change automatically at the same time.
I suspect there may be an issue with the motherboard. I've checked the pin connections and used a knife to carefully separate them, ensuring no particles or debris are inadvertently bridging the pins where they shouldn't be connected.
More photos of the mother boards:
Does anyone know how to identify and resolve this issue?
