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.

SOURCE: F70 ERROR ON PANASONIC AV RECEIVER SA-HE200

This is essentially a protection mode indication. Either the output amp pac is defective or the regulator circuit is bad. Either option could be over $75 in parts plus labor at a local shop.

Let me know if you would like to attempt the repair and I'll try to get you more specific parts information.

SOURCE: Panasonic SA-he75, displays an F70 error.

The F70 error is a code for "protect". See the link below for a general explanation of protect mode. Specifically for your unit, the output amplifier IC has failed. This can be replaced, but the parts cost will be in the $100 range. Please update this if you have further questions.

Thanks,
Dan

I have panasonic sa he7. My problem is error f70 overload.There was a electrical failure in my speaker. After that reciever showed f70 overload error. Fuse is not the original one. After that every ti

You may have a speaker connected that the amplifier cannot drive. Your receiver is compatible with speakers with 6-8ohm rating, however, even though your speakers may be operating within that range they may also have low sensitivity.
With the receiver turned off, disconnect the power cord for a few minutes, reconnect and then power it back on. And while you're behind the unit, that would be the convenient moment to inspect your speaker terminals...check for cracks, evidence of arcing and any stray pieces of strand wire that can touch the chassis or other terminals. If any of those conditions exist then that can a root cause of the problem and will have to be repaired.
You must also ensure that all of the chassis vents are not blocked and the unit does not have another device on top of it that also generates heat as well. In any event, keep it cool.
After that, enter into your speaker setup menu and adjust your crossover to a higher point for whichever speaker you had the failure. This will help control the overload condition, if in fact, it is being caused by your amplifier ability to drive your current speakers.

If after all of the above is performed and the condition still exists, try speakers with compatible ohm rating but higher sensitivity.

Its showing F70 error on display. Only workd on DVD mode, when i turn it on any other mode it just shows F70, switch power off. All fuses are ok, no any visibly damaged components

The fuse is a part of the problem it is for safety measures
the problem is in between the power supply regulators, capacitors and power amplifier circuit board.
usually a regulator or an output transistor can cause this error.
hope this helps.

F70 problem

Look up "Panasonic F70 error" on Google and you will find plenty of discussion about this problem.

The F70 is a blown fuse error. It looks like you can can the fuse yourself, if so inclined, otherwise send it to a service agent.
