You can find user manuals on line. For more information here you will need to provide more information.

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.

On that model you cannot listen to channels A and B at the same time . If you do want to hook up both make sure you series wire them ....hook the positive "+" of speaker "A" to the amp "+", then connect the neg "-" of "A" to the "+" of speaker " B " and then the "-" of "B" to the "-" of the amp . This is because the amp only supports 6 to 16 ohm loads . Please search series vs parallel speaker wiring on Google and look at the image diagrams if you have any confusion about it

Hi can you add a foto of the error plz so i can see what you have!

"I accidentally touched a speaker wire to the metal spikes on the bottom of my speaker. " This action makes +B voltage (positive voltage) short to ground. You may assume 2 power transistors mounted on a large heat sink are defective. Now try to remenber which speaker terminals was accidentially shorted. Then check this terminal or you should check all power transistors mounted on the heat sink, by measuring the collector and emitter resistance. Normal value is Mega ohms and all white 3 pins resistor with 0.22ohm should also be checked if they are open( infinity resistance).I have tried to reset it several times to no avail. Of course, due to defective power transistors. Is my receiver done? Yes. I wrote detailed troubleshooting steps used in onkyo service dept. a year ago, just find it out in my answers.For your case, DET. PROTECT: I instead if entering debug mode. NG L R BL BR, This amp is under DC protect.

Hello When the device stay on STBY it means it is in a protection mode. means also safe mode so it wont make more damage. Try this my friend. 1: please check speakers cables. If you have some knowledge in Electronics test on the supply board in/out volts and power Amp voltage (Not on the transformer) check with diagram as shown

See photo.

"Volume knob not working on my onkyo tx-ds656"replace the volume knob but check the volume control IC first such as voltage and whether an analog signals come out by an oscilloscope.and " lost remote " Check if the onkyo remote is working, by:(1)point a mobile or a smart phone camera at an onkyo remote control.(2)Don't take any photo.(3)Now the remote picture is on the mobile or smart screen.(4)Press any remote control key.(5)White flashing light can be seen if remote is ok.(6)If remote is fine, replace the remote senor on tx-ds656 with same part number.

You need to check several voltages(1)-VP(2)FLAC1 and FLAC2(3)drive signals to FL needs a digital storage oscilloscope to observe waveform. Or replace chip directly. This is a full picture.

"Tone Control is not working when I push the button but the light will go on and off." Download TX8511 service manual. Tone control circuit involving balance, bass and treble circuit is defective. Check circled componets or replace them all. If replacing them all, balance circuit should also be replaced.

Good luck my friend. A needle in a haystack, sorry!!

“Hi, Onkyo TX SR 705 have a super cap for memory presets ou eeprom?? ”Yes, it may have a 5.5V cap with 0.1F for memory to use .When the power is down and it loose the presets, whats the problem?? Tks Don't worry, it will be charged up when the amp is On. The longer the time it is on, the longer the time it charged.For your case, replace the cap mentioned above can fix the problem. I will post the photo later.After checking the onkyo TX-SR705 service manual, however, I did not find any capacitor of 5.5V 0.1F on the schematics. The EEPROM is powered by a polar capacitor. See photo. Step of repairing (1)Download the onkyo TX-SR 705 service manual.(2)Find out the EEPROM located at Main Microprocessor Unit.(3)Replace the capacitors of epprom(4)If the problem doesn't solve, copy all data form the old EEPROM by a SPI EPPOM reader.(5)Buy a new SAME MODEL EEPROM and copy the old data to the new one. (6)remove the old defective one from the circuit board(7)put the new one with data copied to the circuit board.

"ONKYO tx-nr737, when I am connected via Bluetooth to my iPhone for music I get a SP Wire message. " The wifi and bluetooth part is defective, replacing it may fix your problem. See photo how a good wifi and bluetooth works.

“HT-R340 DSP Debug Mode” Does it show DSP ??????? Place a photo here to show more detail if you want.

does it make any sound when you click the eject button? please explain the problem in brief.

" I have an Onkyo tx-nr807. It stopped putting out sound and where it shows all the speakers that are on, the subwoofer light is flashing. " If speaker indicators are on, you should check DIR and speaker relay drive voltage if +24V is present.

No, wd40, "please" first try checking the solder connections, 9 times out of 10 it's bad solder connections. Not every issue with older Electronics is Cap related!!! Onkyo is super easy to repair like I mentioned earlier, check the solder connections first, also check the ribbons, unplug the clean the contacts with DeOxit5, if you still need help, don't hesitate to contact me, good luck!!!
