Some parts are avaialble but you will need to do your own searching on the internet. It is unlikely that Sanyo will supply components. Specific Integrated circuits could be impossible as they are manufacturer's own designs in a lot of cases. In the current way PC boards are replaced in their entireity and the old one thrown away. The old days of component repair has virtually disappeared.
