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!!!

"when first turned on, drops to tv, once reset, stays on cab/sat" Maybe the EEPROMused to STORE user information goes wrong.Check(1) voltage supplied to EEPROM +3.3V. at pin8(2)C226 47uf 16v(3)C225 10k nf(4)R256-257 4.7K (5)R260,R262 100ohms if they are correct.If correct, buy a reader to read the data stored in EEPROM and burn it to a new EEPROM. To locate IC203 CPU then find IC204: EEPROMsearch in taobao or google"Taobao USA/Hong kong/Tai Wan"then search"GZUT EZP_XPro V2 USB " will be cheaper <15USD. Maybe this can be used.https://world.taobao.com/item/559202211788.htm?_e_pi_=7%2CPAGE_ID10%2C8206437564

Must be DSP problem no matter what model it is. TX-SR/NR OR even RZ Series.

(1)If old model TX-SR/NR, you should replace the BGA DSP Q3001 "D830K013A/BZKB" TO "D830K013DZKB"IF DZKB get damaged, replace it with same DSP Chip-DZKB.
(2)For Tx-SR series, the DSP Q201 TMS320D788E001B SHOULD BE replaced with same model.
(3)For new model, RZ series the DSP Q3404 CS49844 should be replaced with same model.
(4)Crystal marked X201/3001/3404 should be replacd.

If it has a preamp out use that.

Very easy to fix. If you want to DIY, just send an email to me This is a very common faulty found in Onkyo av-amp. You may think it is weird. I must tell you,however,I buy faulty av-amp to repair and sell them out. Hence, I will not tell you here.

The TX 8555 can drive the speakers directly but if you want to use the equalizer then you need to add an amplifier to the system so that you can feed the pre-amp connections from the TX8555 through the equalizer and then into the amplifier to drive the speakers. This is because the TX 8555 doesn't have a loop back function for monitoring recordings.

I suggest you check the settings to make certain everything is correct, the way it was when you first set it up. OR you could try and reset the thing by setting it all up again. If you can find the factory reset on the unit, do that and then do all the settings again.

maybe the speaker is defective, conect diferent speaker

Try to use S/PDIF (Coax or opt)for audio input instead of HDMI may solve the problem.

You should reset the amp to factory default to see if audyssey disappear. Unfortunately, over 90% using reset to kick audyssey out does not work. What can I do? Calling onkyo to repair is the only option. Never use this function, wifi and bluetooth in onkyo av-amp except warranty is not expired.

No, you cannot do this. Onkyo is just a "receiver" to receive signal not a "transmitter". The receiver requires a "host" to send signals via bluetooth to it in order to playback instead of sending signal to another receiver, your bluetooth headphone. Bluetooth earphone also needs a host (a smart-phone)to send signal to it to playback for you. Any attempts to ask onkyo receiver to send signal via bluetooth will be in vain.

“remote does not operate volume, have to increase decrease manually,” (1)Open remote cover.(2)Clean remote PCB and volume buttons with dry cloth.
(3)add some sliver paint on black colour volume buttons.
(4)wait for paint to dry
(5)remote can be used again.

My onkyo tx-v940 has very low volume. You shouldCheck the voltage supply to both +B and -B voltage.If both voltages are low, the voltage amplification via differetial and voltage amps will be low. Finally, low Volume due to power = VI. If V is low, so does powerOutput. The negative voltage can also be measured as that of +B with black probe clamped to heat sinkby a crocodile clip.

May hav take it apart n fix obstruction or ask a radio store

Enter debug mode to see which type of protection causing amp to shut down.

Apparently so, according to advertisement: https://www.blu-ray.com/Onkyo-TX-SR674/13978/

Download HTR530 Service manual.How to measure voltages?(a)connect the black probe to the heart sink via acrocodile clip. Heat sink can be found easily if you are looking for 12 power transistors.(b)the red probe can connect to any interested points,for example, the POFF (see video1)Check voltages first: POFF(must have. And check 3 components circled in blue see video 1 the last measured voltage) ,10VS (must have)and 12V and also the MPowerd voltage (see video 1) Video 1 shows the MPowerd voltage The lst measured voltagethe - MPowerd voltagemust be ZERO when the amp is switched ON.. Are these voltages present?If so, check reset or you can replace them directly (circled in yellow See video2 and video3)Plug the amp, to see if it is working.If not ,replace 3 components circled in red.If not working again, you can replace the crystal X701,a component 6 MHz, not easily damaged (see video4).If also not working, CPU is torn out.
