Programing Mode Backward

Don't know that you can actually reset this unit like the new digital receivers. It does have protection circuitry that will shut the unit down in case speaker wires are shorted or if speaker impedance is less than the indicated rated impedance of the amp. do the following:
1. Turn off power and unplug from wall.
2. Check all connections and correct if needed.
3. Turn back on after 1-2 minutes.
If unit is still in protect mode you may want to unplug everything from the unit and then power back up to see if the problem is internal or external. If it powers up correctly then the problem is external. Power back down and plug in one external item at a time and power back up between connecting each item to see which item causes the receiver to go into protection mode.
If problem seems to be internal I'd recommend taking to an electronics repair shop if you aren't comfortable with taking apart to check fuses, terminations, etc. There may be a 5-amp fuse in the power plug head also.

Sharp updated the procedure for resetting the E1 code.

1. unplug unit
2. hold the Power button while plugging the unit back in
3. keep holding the Power button until the unit beeps
4. unplug unit again
5. plug it back in and it should be good

Here is the updated user manual

follow directions from the owners manual. while unit is powered up, unplug power cord from back of unit - wait 5-seconds. Depress the DVD open/close button while re-plugging the power supply cord to the unit. LG splash appears onscreen and unit goes into re-set. you do not loose any of you programing or settings.

HI, this is a reset procedure that this unit is trying to initiate. there has been a surge of some sort that the system has survived but, there is some lasting damage as well that has resulted in a slight programming error within the mother board.

This unit has a program that was installed at the manufacture. it runs the basic operations. there has been some major damage that is causing the internal program to stall and reset itself. the only way to reprogram is to send it back to the manufacture or, you can locate a local repair depot through Onkyo. the Onkyo techs are the only option when re programing is needed.

Just ot be safe, try unplugging it for 20 minutes or longer - do not unplug it for a shorter period, or you will not get the desired effect (this has a 15-minute internal memory, so a longer than normal unplugging is necessary).

If this happens only when connecting the receiver, chech the receiver cable. If the cable is fine, receiver connector at the back of receiver is faulty.

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

Microprocessor reset.

For US and Canada:

1. Unplug the power cord from the wall outlet, then plug it back in while holding down the POWER key.

For other countries:

1. With the power cord plugged in, turn the POWER key OFF. Then, while holding down th ON/STANBY key press POWER.

First, move the slide switch at the left rear of the top of the unit all the way to the right. You'll see the colon blinking, indicating that you are in 'set' mode. Now turn the dial that surrounds the ON/OFF button on the top of the unit. You can move it clockwise or counterclockwise, to change the time forward or backward. When done, move the slide switch back to the far left. Done.

An E1 error is automatically generated after the AC runs for so many hours to remind you to clean the filter. The owners manual says to clean the filter and unplug the unit, then plug unit back in and code will be reset. However, a User review stated that his code was not reset until he followed a fairly simple routine. "Unplug the unit. Hold down the power button and plug back in. Wait to hear a "beep" and then unplug it again. Plug unit in again and it should restart without E1 code."

Unplug all the speaker wires first, then unplug the unit from the wall for at least 24 hours, The plug back in without the speaker wires or anything else plugged in. Then see if it goes to the protection mode. If it does not, plug in each speaker at a time, and see if any speaker, when hooked up, makes the receiver shut down. If it does shut down, My friend, I'm afraid you will need to take this unit into a repair shop, OR get a new unit. Good Luck
