Question about Panasonic SA-HE70 Receiver

1 Answer

Overload? i had this reciever for a while and recently i think i hooked up way too powerful speakers to it and it went into overload mode and usually when it does that you can just shut it off for a while then turn it back on and it will be fine...but now as soon as i turn it on, it clicks into overload mode and wont go out of it....i even tried it with no speakers connected and it still does it...i think i just blew it...

    I think the house was hit by lightning recently and now about a second after the receiver is turned on it clicks and displays overload. I disconnected the speakers and everything else that was connected and it still displays overload shortly after it is turned on.

    I have the panasonic sa-he70 av control receiver and it continouosly clicks off and says overload. It has been working fine for a while but just recently it is starting to malfunction. it works good when i hit the reset button and it plays the sub and two front speakers only. When I try to change to SFC mode and turn the volume past 40 it overloads instantly. I have checked all wires, disconnected speakers, checked for overheating and it has worked in the same circumstances for the past two months. whats going on?

From the manual, you may have seen this: Switch off the unit, determine and correct the cause, then switch the unit on. Causes include: ?Shorting (bare wires touching) of positive and negative speaker wires. ?Using speakers with an impedance lower than that rated for this unit. ?Straining of the speakers through excessive volume or power. ?Using the unit in a hot environment without proper ventilation.

Have recently had an "overload" displayed. Have


HI:
Usually receivers go into overload due to a bad speaker make sure you disconnect the speakers also to make sure its overloading from a bad speaker. If the unit still shows overload even with all speakers disconnected, then your main amplifier output has a short usually a shorted output transistor is the cause. Unplug the speakers one at a time to and turn the unit on after disconnecting one of the speakers , to determine which speaker is at fault.

My reciever plays then cuts out


They don't overload from missing speakers. I'm curious, what buggered the one speaker?

Examine all of your speaker wires carefully to be sure no unintended contact is made between them and anything else.

Is "overload" being displayed?

“OVERLOAD” starts flashing on the display.

Speakers are overloaded because of high volume.

1. Press STANDBY/ON on the front panel to turn off the receiver.
2. Stop the playback source.
3. Turn on the receiver again, and adjust the volume.
----------------
Speakers are overloaded because of short circuit of speaker terminals.

Press STANDBY/ON on the front panel, then check the speaker wiring.

If “OVERLOAD” does not disappear after turning on the receiver again, unplug the AC power cord, then plug it back in again.
If speaker wiring is not short-circuited, contact your dealer.

Reciever overloads/recently installed blu-ray player


Overloads are generally heat- or current-related. Digital inputs don't have adjustments (all 1's is as high as they go), so I doubt there is any relationship between the Blu-Ray's optical cable and the overload.

You've said what doesn't affect the problem, so what's that leave? I'd look at shorts or mismatches between the amps and the speakers.

My Technics AV Control Receiver SA AX530 is in overload


An amplifier should never be turn on without speakers, it will overload internally.
make sure speakers work and try again.

Says overload


Your speakers may be underpowered by your receiver. Check the watts and impedance of the speakers, and the wattage of your receiver to make sure they closely match. (impedance is calculated in ohms- indicated by an omega symbol written near the wattage rating)
"Overload" may also mean that the amp went into protect mode, and that means that you're OVER-powering your speakers and it wants to protect them from damage due to impedance mismatch.
But- if the impedance and wattage match between the speaker and the receiver/amp, you should check the polarity of the speaker cables (+/-) BTW- never put 2 speakers in 1 output- that will almost always cause something like this and will sound bad.
I hope this helps.

Overload


Have you checked your wiring connections? Wires could possibly be touching each other making it short out and giving you that "Overload". If not that then I would say it could possibly be a fuse that has gone bad inside. ??? Just some suggestions. The reason I say that it could be the wiring is because when I hook up a system and the wires accidently touch each other it overloads the system past a certain volume. Again I would check my wires first and move on from there.

Overload on Technics SA DA10


Cracked solder joints due to excessive heat cycling. Do not place in a shelf system. Top MUST be open for 1 ft. or better for proper convective cooling effect. Mine suffered same fate but repaired locally.

Overload Problem


If your rec'vr worked with the original front and rear speakers, the new speakers are either defective or ar the wrong impedance.
Also, I find this confusing: "I connected the wiring for 1 of the front speakers to the connection on the rear of the receiver". This may indicate wrong wiring connection. Make sure you have connected the speakers properly
