My teac ag-790a 'protect' error message on display. When I brought it to the audio shop for repair it worked fine; at home again the same problem? What is the problem? Tx.


Hello
Check the putput wirings to speakers. If any of them has short circuit, the set will go to protection mode. You can understand it well, as it did worked fine at the repair shope. The set has no fault at all, but the wirings, connects to it have.
Just power ON the set at your home, without connection any output or input to it. See, it will not show any protection mode display. Switch it OFF. Connect the output to speakers, one at a time, and switch ON the set. Just do it for all other speakers. This way, you can find out, which speaker line causes the set to go to protection mode. Fine out the reason.
Never connect any input to the system, until works fine with out showing any protection display.
I helped you somewhat fine, I assumes.
Ok.

PROTECT MESSAGE


It senses an error or problem and shuts down. Try disconnecting all the cables and wires attached to it. Try it again. If it still shows protect message, it is an internal fault and requires a repair shop. If it clears up, then the problem may be a shorted speaker wire. Correct the short when reconnecting the speakers.

"Protect" Flashing


In all likelyhood, one or more output transistors have failed. Please confirm your model as STR-DE335 and I'll post the probable parts that need to be checked.

Getting a "Protect" message in the display which then shuts down


The speaker wires were al little frayed, so I cut and stripped new 3/8" leads and when re-inserted the receiver worked fine. The problem was a short from the frayed wires touching either the back of the receiver or some other metal near the terminal.

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
Good luck

What failed component causes protection error message to display right at power up.


well, i just got this thing from a friend. its a Denon AVR-800. when powered up it displays the stops, just before finishing a -protect- shows up. There's a little red light standby light that blinks off and on also. i think that has to do with the internal problem. any suggestions?
