Hi there,
This is a problem related to the out put section, try disconnecting alls the speakers from the receiver and turning on the unit. If your unit comes on then mostly any of your speaker or associated cabling is getting shorted . If the same problem persists then usually the amplifier needs service attention, refer to a qualified engineer.

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.

I have a Technics SA - DX750 Amp Everytime I turn it on I get an error message F70 and then it requests that I turn the power off. This is all it does now, so sound. How do I solve this issue I have...


Hi!

The F70 error certainly indicates a blown fuse inside.
The real problem is why the fuse is blown: there are only two possible reasons
1. there is a short circuit on the output (lines or speakers)
2. you have a blown output transistor (and that means some work and skills to replace).


To be sure, please change the fuse with a same rated fuse (buy more than one because it can blow again). Disconnect the speakers and turn the amp on. If the fuse blows again, it is sure something wrong with the output transistors. If the fuse remains ok, then please check all the wiring to the speakers.

Hope it helped.

Regards,

Bogdan

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

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.
