I have a freshman understanding of JP1. I have cable and have had success setting my equipment up and am still learning. Can we use JP1 to enter this setup code, or do we need to create a new device upgrade. If so, Alternately, we can probably learn the required functions, but a setup code or pre made upgrade would be preferable...we tried the several Sony upgrades available in the Yahoo files area, with no success.
Funny thing, when we learn the Power function from his K750P, it works, and also powers on his OLD Sony receiver, but the setup code that operates his old Sony does not work the new one!
thanks for any advice...
