Re: Panasonic AV Control Receiver error code F70

dougie Posted Nov 06, 2006, in response to:Ray Binstead

...additional info: this morning I spent half an hour on a quite pricy service hotline and had a very knowledgable technician at the other end. Fact: Error F-70 is caused by some faulty communication between central processor on the backside of the front panel, and other processors. Other processors could be: DSP, Volume control, Input selector or high voltage breakdown switch A digital board carrying the DSP with improper power attached (fuse blown or fuse got high impedance) causes the same error, because DSP cannt reply to commands. Therfore the blown fuse isn't the only answer available. Like in my case I still get F-70 error even all voltages are fine. If somebody would sell me his broken SA-HE90 or similar Receiver, I would like to try go build one working Amps out of two broken ones. Just send me a note to dougie@gmx.de Greetings Ralf
