@normalta it’s an older piece of equipment and parts are getting tougher to find. You will have to scour online for this. You said it’s the motherboard which you would need. Pioneer calls it the main assembly part number AWV2225. Just let us know why you think it is the main assembly that you need. Tell us the symptoms of what is going on and if you need to show something, post some images with your question. [guide|21499]
