Onkyo sound popping / protected shows in the display

Try resetting the AV receiver To reset the AV receiver to its factory defaults, turn it on and, while holding down VCR/DVR, press 8 ON/STANDBY. "Clear" will appear on the display and the AV receiver will enter Standby mode.

It is possible that the protection circuitry has been activated. Remove the power cord from the wall.. Disconnect all speaker cables and input sources, and then leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect only the power cord and set the volume to maximum. If the AV receiver stays on, set then the volume to minimum, disconnect the power cord, and reconnect your speakers and input sources. If the AV receiver turns off when you set the volume to maximum, disconnect the power cord, and contact your dealer.

If the standby light is lit it and the unit will not boot it is most likely that the protection circuit has been activated. If there is no standby light then check the fuses. These units check that the power supplies are operating near specification. If a capacitor or resistor in the circuit, or a broken solder connection the unit will shut down. Because of the temperature the thermal cycling around the power supplies a broken solder joint can occur. This will make for an intermittent operation.

Hope this helps.
Failed resistor or capacitor

possibly a problem with the receiver. first you could try a power cycle, unplug power cord of receiver for a minute then plug it back in and try again. if you still have the problem disconnect all speakers and see if the receiver will stay on.

No! I'am afraid not, if you have checked your wires carefully and it checked, the audio output semiconductors will require a technician to remedy the problem.

Hi,
Please reset Onkyo receiver that will solve noisy sound problem, to reset the receiver, press and hold Video-1 button on unit and press Speaker-A button. Display will show *Clear* that means receiver has been restore on default settings, turn it On and check sound.
Hope this will help.
Thanks.

It appears lightening has damaged your router. Do you have a surge protected powerboard and do you plug all your computer equipment into this powerboard?
If you do not have a surge protection board, I suggest you install one to protect your equipment.

Turn everything off but the receiver. If it stays on turn another one on and see if it pops off if not continue. Most receivers have a pause start to prevent power surge. If it continues remove the protector and try the unit alone.

Lightening may have caused a surge on your power lines to the house and to the outlet the TV was on.
Do other things work on that outlet? If not you tripped a power breaker.If they do work check this.
Unplug the TV for 2 min or more and plug back in.
Try bypassing your surge protector you had it plugged into. It could have died when the lightening struck.
(no surge protector?) Bet you'll buy one for your next TV.
Look for 3000 joules and up rating for a surge protector and insure it has protection for a cable/antenna input too.
If this doesn't work the TV may be fried or internal fuse blown.
Time to take it to a repair shop or depending on it's age (5 years+) it may be time to buy a new TV and surge protector.
Near Lightening strikes can effect appliances from several inputs that could be affected from outside like Power, Cable, Antennas, Phone Lines that come into your house.

After few sec when you turn on your receiver did you hear a click noise ? if yes your receiver is OK not in protection mode if no click noise is output protection in that case you must return where did you buy for service and update firmware a lot of update
However you can reset your receiver and debug the DSP section ( digital signal processor ) as follow
To reset
1. Press and hold down VCR/DVR button, then press STANDBY/ON button when the unit is Power on.
2. After " Clear " is displayed, the preset memory and each mode stored in the memory are initialized and will
return to the factory settings, and turn to Standby mode.
Now turn back on and check if it work or not and make sure check input mode such as analog or coaxial or optical input if stil no sound then debug DSP as follow
To set in DSP debug mode
1. Press and hold down DISPLAY button, then press STANDBY/ON button while the unit is powered ON.
The version number of m icroprocessor is displayed only for 3 seconds.
Main:
8 1.05/07903A
2. Press TONE+ button within 3 seconds above, the version number of 1st DSP is displayed.
DSP 1st:
SR8051:07601A
3. Press DISPLAY button while the 1st DSP version is displayed. The status of DSP and DIR will be displayed.
E1A48K0N/0FFPo
FFFFFF0 0 000
To exit
Press STANDBY/ON button.
Then unplug the unit for 30 sec then plug in it should work now if not you need to return it to 1 of the service center Onkyo in your town to repair it
