Recently couldn't get the receiver to shut down. I unplugged the unit to reset. When I plugged the unit back in, it switches on and off alright, but where my Plasma TV previously operated through the Video 1 selection on the receiver, it now has to be on DVD! I receive a message when selecting Video 1 stating no sync. no signal! When attempting to play a DVD in DVD mode, I get image, but no sound. A message appears stating that the Digital DTS signal is turned off. The DVD works fine in CD mode. Can you offer assistance?

Before you reset, are you doing this because the amp went in to some sort of protection mode?
Resetting will allow the amp to redo the self diagnosis. But if the problem remains then the amp will shut down again. Resetting doesn't fix things like bad wiring or blown output transistors. So only reset once you are sure you've checked through the system for any problems.
As a safety measure, disconnect your speakers before doing the reset. If the amp goes in to protection again then it is an indication that there are either shorted speaker outputs inside the unit.
Unplug the unit from AC power for 30 minutes, and disconnect all of the speakers and other associated equipment. Upon plugging back in, press and hold the power button at the same time for 5-10 seconds to force a hard reset.
If the unit starts up normally start connecting the speakers one at a time (shutting the power down before connecting each one), until one of the speakers causes the receiver to shut down. This speaker is faulty and would need to be replaced.
If the unit does not power up with NO speakers connected, then it needs the output transistors replaced inside the unit. These directly drive the loudspeaker outputs on the receiver itself, and one or more of them being shorted (closed circuit), will trigger the error on the display of the receiver, and it will not go off until the problem is repaired. They are not user-replaceable as they are PCB mounted, and thermally coupled to a heatsink. In this case, the unit is in need of service.
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.
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 Onkyotechs 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.
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
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
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
