Question about Technics SA-DX750 Receiver
According to Technics reference manual, turn the unit off, unplug for a few, plug in, turn unit on. Consult your "dealer"(authorized repair person, i guess) if light remains on. But doesn't say what f70 means, or associated with.
Unplug and open up the unit, and check the internal fuses on the circuit board. Also check for proper speaker wire hook up. Re-seat the connections. Visibly check the speaker wire runs for shorts, cracked casing, cat/dog chewing. etc.
Hope this helps.
