The system has detected a fault in the output section. How much are you asking of the system? Greater than 50%? That will push most systems to their limit in a short period of time...accordianman

SOURCE: Panasonic SA-HE100 5.1 system error code F70

I was able to fix this problem by replacing a fuse. Remove the cover (7 screws). Directly behind the fan are 2 boards with 5 fuses on them. The boards are 1 over the other. The fuse I replaced was labeled F5 and on the top board with the fuse facing down on the underside of the board.

It could be an overload from two speaker wires crossing, check the owners manual for error codes.

Digital input glitch, switches randomly from analog to digital.


what connections do you use for the device you are listening to, and what device are you listening to when this happens. you should use either an analog, or a digital connection to a device, but not both

Digital surround mode doesn't work,just analog dvd 6ch.input


Failure of the sound processor. All you can do is to remove the cover, clean the insides, check the cables to make sure they are still firmly plugged in and then measure the 5 volts power line from the source. If all appears OK the the processor has died - a replacement board is mandatory. It will be cheaper to buy a new receiver .

Problem with Technics SA-DX850


SA-DX750 (sister Model to SA-DX850). Showing error code F70, after a few minutes running. Checking the power rails revealed +5VA and +5VD, on the Digital Circuit Board 'A', dropping to about 2V, when fault occured. F5, T1A, on the Sub-Transformer Circuit 'M', was subject to occasional blowing. The problem was traced to an intermittent break, in the printed circuit board conductor, in the vicinity of Q1702 (+5VD regulator) collector, on the Digital Circuit Board 'A'.. Repairing this cured the problem. Note that removing F5 (above), or disconnecting CN702, CN1000A or CN904B, on the Digital Circuit board 'A', also causes this error code to be displayed. Failure of the audio output ICs, IC651 & IC801, is apparently the usual reason for this error code being dsiplayed, but it is worth checking the power rails viz. +/- 25V (Fuses F3 & F4, T6.3A, on Sub-Transformer Circuit 'M') +/- 55V, +/- 14V etc.
