My Panasonic mini system died last weekend. It just shuts off
immediately with a "F61" error upon powering up. I tried replacing the
fuse, but that didn't appear to be the issue. Research on Usenet
suggests that the output IC may be bad(?)

Is this something which I might be able to easily fix myself? If so,
does anyone know where I might be able to find a service manual or
diagrams for this unit?

If I need to take this to a repair shop, how much might a repair cost?

Thanks,
Y.M. Lim
