Does the display show you are in protect mode , or is a light indicating that? The unit automatically switches to standby when the
"Hardware" - "Power Management" - "Auto Standby"
setting in the Setup menu functions are set. The protective circuit function may have been activated.
If this has occurred, "AMP Diag Mode" appears on the
display when the unit is turned on again, and the unit
enters diagnostic mode. If the results of the diagnosis is
that there is no problem, the "AMP Diag Mode" display
disappears and you can use the unit normally again. If
"CHECK SP WIRE" appears on the display, the speaker
cables may be short-circuited. Make sure bare speaker
wires are not touching each other or the back panel of
the unit, then turn the unit on again. If "NG" is displayed,
immediately unplug the power cord from the wall outlet
and contact your dealer.
• The protective circuit function may have been activated
because the temperature of the unit rose abnormally.
If this happens, then the power will continue to turn off
after you have turned the unit on again. Make sure the
unit has plenty of space for ventilation around it, wait for
the unit to cool down sufficiently, and then try turning it
on again. This is out of your users manual.
General suggestions are to remove all speakers and speaker wiring with unit off. Turn on and see if problem has stopped. If not, let unit cool down if warm and try again later. If problem is still there it needs repair shop work. I fht problem went away, shut off power and connect one speaker at a time and testing. Keep adding speakers one at a time with power off and see if a bad speaker or wire set can be located
I don't know the answer but I suggest obtaining and reading the user manuals before your purchase will give you that information.
It will then be important to ask the supplier the answer and then the responsibility will be theirs.
If the amplifier provides either a 3:1 or 5:1 output there will be provision for a subwoofer - but what type of subwoofer (active or passive) will be hidden in the specs and if you already have a subwoofer, in the specs of that.
When buying a new amp and preamp the last thing you want is mismatch or overload conditions that will either produce a less than good sound or perhaps stressing the amp.
As a matter of diverse interest, in the old days before subwoofers had been invented the hifi enthusiasts seeking the perfect sound developed the three rack amplifier for domestic use. This type of amp had been used in cinemas for a long time and basically consisted of three amplifiers each built to handle a different frequency spectrum - one amp would drive the tweeters, another the midrange and the third would drive the bass units or woofers.
Another thing hifi buffs did was to introduce a ghost speaker driven by a mono amp that derived an input across the left and right channels.
My opinion is the best sound still comes from a quality 10 or 20 watt tube amp into quality low power handling speakers with cabinets as big as a sideboard. 300Mw is the average power needed for a good listening experience in the average lounge or bedroom.
https://www.youtube.com/watch?v=gfJEw-VlpWYHold the "VCR/DVD" button while pressing the "On/Standby" button, and the receiver should enter "Standby." Turn it on again by pressing the "On/Standby" button. Bear in mind that this will clear all the presets and other settings - but it may be those settings that are causing the problems.

1) DTS will only work through a digital connection (coaxial, optical, or HDMI) between your receiver and dvd player. DTS and Dolby 5.1 cannot carry a signal over red and white rca connections.
2) After number 1 is solved ensure the reciever is set to the digital channel, your DTS-HD in this case, or in an auto mode.
3) Finally the most important is that the signal is a DTS signal. Start a DTS capable dvd, go to the sound menu and set it for DTS.
If it can recognize some discs then that cd may be faulty, or if it is unable to see any discs then that unit has a problem.
You say its brand new, some machines have "transit screws" to remove but I did not see any mention in its instruction book.
So its possible the mechanism or laser unit is faulty or damaged in some way for that I would refer back to where you bought it or the service company for Onkyo, as you will be at risk if you tried to fix it yourself as you will lose out on warranty.

Hi there's this website something like reliable-store and it is very amazing for manual for repairing servicing anything someone on fixya recommended it to me and I thank him even today They have full manuals and it's verrrrry cheap and mine I got free in offers 3rd time I bought it, I also had an issue with the file so the girl replaced it in 30 mins there is one website more but i don't remember its name it was 2 years back bitman something link this Try these out brother
Hello Tony Ramsey, as you comment, you may have problems in the output of speakers or in the speaker connection cables or in the speakers themselves
I suggest you disconnect all the speakers, check the cables that are in good condition, without damage to the plastic or joints that could generate a short circuit
Go reconnecting cables and speakers one at a time, testing if the fault appears
There could be the possibility of internal component failure, in this case, look for a specialized technical service
I hope you can solve the problem
Greetings Franco Dosil

Here is the user manual https://www.intl.onkyo.com/downloads/manuals/pdf/ht-r393_manual_en.pdf
First thing to do is to disconnect everything from the received,, and take it to another AC outlet to plug it into, and try again.
The unit does not have an external fuse, and it is not recommended to open it.
Here is the service manual for qualified persons https://www.vintageshifi.com/repertoire-pdf/pdf/telecharge.php?pdf=Onkyo-HTR-393-Service-Manual.pdf
You have already pointed out the problem:
Problem is Det.Protect: I.
How to fix :
(1)download 545/535/525 service manual.
(2)check all power transistors CE & BE resistances
if theyy are very low ,0 ohm, or infinity.
(3)check all 0.22 ohm resistors if they are open
or turning greater.
(4)Check the biasing circuit with a small rating
transistor and an orange color variable resistor.
(5)Check all channels.
Hi Bob, for what you say, your remote control has problems in the ignition, try to disassemble it and clean the plate of the accounts, with a little liquid glass cleaner, you will observe, as a accumulation of rubber residue, on the contacts in the remote control platelet, clean and dry very well
DO NOT USE ANY KIND OF ALCOHOL
Let it dry very well, then assemble it again and see if it is solved
Comment the results
Greetings Franco Dosil
Hola Bob, por lo que comentas, tu control remoto tiene problemas en el encendido, prueba desarmarlo y limpia la placa de los contactos, con un poco de liquido limpia vidrios, vas a observar, como una acumulaci?n de residuo de goma, sobre los contactos en la plaqueta del control remoto, limpia y seca muy bien
NO USES NING?N TIPO DE ALCOHOL
D?jalo secar muy bien, luego armalo nuevamente y prueba si se soluciono
Comenta los resultados
Saludos Franco Dosil
