Technics SA-DX940 I am having the same problem. It just started occuring and is getting frustrating I recently got a "Overload" display during running the amp. The message promps you to power-off the device. After truning amp back on it stay's powered up until I increase the volume; then shuts down again prompting me to "power off, overload"! Please help us

Sounds like an electrical problem. Check connections to battery remove & clean them , check + wires to engine, to power supply for the engine management.

OVER CURRENT ERROR – Display shows 8E. IPM fault signal (this is caused by the overload of the MICOM INTO during motor action).
IPM: Integrated power module. The IPM controls the motor.
If the fault (low signal) happens to be sensed even once during the washing/rinsing stage, the motor stops immediately. However, during the dehydrating stage the signal is to be sensed, when the number of signals reads more than 6 per 500ms during the Washing or Rinsing cycle action.
If the motor stops working, in one direction ten times, “8E” Error is displayed.
During dehydrating, when the overload is sensed, the motor stops working at once and then feeds back to the initial stage of the dehydration unbalance sensing. When the feed back has occcurred twice, Error “8E” is displayed during the dehydrating unbalance sensing, No error happens by overload sensing. When it happens at more than 800rpm, the process is stopped compulsorily. Power SIW OFF can clear the overload error.

would advise calling a tech... hope this helps.

Hi,

I am giving you some steps, which will help you to determine where the fault lies. In this situation like yours, this is the best I can do. Please come back to me the result and I'll help you to resolve it.


- Whenever the distortion is occurring, fix it to an external monitor/TV (if you have such facility). If the distortion does not occur there, your display is gone.

- Check if the distortion occurs during booting. That is, before any drivers are loaded. You need to look carefully. If not, it may be a faulty driver. Sometimes, drivers malfunction due to conflicts with different applications. This can be an application you have recently installed.

- If distortion occurs during booting, it may be faulty graphics card. To check it further, you can take a bootable CD/DVD and boot from that, and see if the display is correct; if not, the graphics card is gone.

If your graphics card is an integrated one, you can't replace it, but you can send it for repairing.

Hope it helps. Do let me know.



Good Luck & Thanks,
Shiv.

If the out door fan keeps running and the compressor cycles off that would be the overload in the compressor.
What keeps the windings cool is the refrigerant back to the compressor.
For the overload to cycle it would have to be either not enough cooling back to the compressor or high amp draw, which could be the metering device (txv or orifice) or low on charge, or other things would be a bad capacitor, sometimes a bad start relay not staying open, when compressor gets up to speed or anything causing the compressor to draw high amps.
To check the refrigerant, he needs to check the superheat at the compressor it should be appoximately 12° to15°, and next time the compressor goes off if you shut the power off and feel the top of the compressor and if it's hot 130° or higher it's probably refrigerant.

Check a see if it is when the unit is starting up when the over load happens if so you need a hard start kit

You may want to get an Ohm meter and check between the outputs of the amp yourself. 0 ohms means a short somewhere.
You should also check to se when you're hooking the speaker wires in that they're not frayed and touching hot to ground or hot to the amp casing. hope that helps!

This is what I found:
11. OVER CURRENT ERROR - Display shows 8E .
- IPM fault signal (that is caused by the overload of MICOM INT0 during motor action) is sensed.
IPM : Integrated power module. , IPM controls motor.
- If the fault signal (low signal) happens to be sensed even one time during cleansing/rinsing stage,
the motor stops immediately. However, during dehydrating stage the signal is to be sensed
when the number of signal is more than 6 for 500ms.
- During Cleansing or Rinsing
When the overload is sensed, the motor stops immediately and then proceeds to the next water-flow action.
If the stopping of the motor working is happens in one direction ten times,
"8E" Error is displayed.
- During dehydrating
When the overload is sensed, the motor stops to work at once and then feeds back to the initial
stage of the dehydration unbalance sensing.
When the feed back is continuously happened 2 times, "8E" Error is displayed
During the dehydrating unbalance sensing, No error happens by overload sensing.
When it happens at more than 800rpm, the process is stopped compulsorily.
-Power S/W Off can clear the overload error.
in short: imbalance problem
In a german forum one guy solved the problem by replacing the motor electronics. I am currently experiencing the same problem. I keep you posted.

That same thing happened to me a few months back and the problem was that the terminals of a speaker were not connected properly, check all of your speaker cables, or check for a broken speaker by setting the volume of each one and make sure they all work, you might find the problem there!!!

Check your wires for cross polarity
