I am that customer and am very pleased with the attention to detail in the repair. I (and NorCal715) kept a 4-year old, $600 receiver out of a landfill. My bank account is happier, and should be for some time thanks to the quality of the work. I agree with some comments that the quality of electronics do not seem to be what it was. This is my 7th? receiver in 40+ years. (One sucker literally blew up and caught on fire. The manufacturer said "It shouldn't do that.")! I still have - and used during the repair - a 1980 Pioneer SA-7700 that still works perfectly in it's native audio-only, stereo mode. Thing's a beast. Why is that? Anyhow, I'm impressed by the business opportunity presented for Norcal715 and others with the skill.

Great work! I see this unit is much easier to disassemble comparing to AVR-17xx series. Those ones are complete nightmare.

Awesome video! I have a Denon that keeps shutting off so I came across this video but your trouble shooting is way above my level haha. Might just jump in and see what I see and use it as a learning experience

Your diagnosis method is simply good.

Great job with your trouble shooting skills. Its always fun to watch you work. 🙌

That . Was a clean diagnosis sir. I had an old rare top of the line Nikko receiver with the same issue. It had a regulated power supply . I changed the output transistors on the bad channel but still hummed bad. Took it to Star Track audio repair. A year later I called inquiring about it. HE TOOK IT TO THE DUMP! You have a new subscriber here. You earned it!

Love your videos too. I learn things when I watch them. I used to work on recievers when I was younger. But those back then were much simpler to diagnose. No computer or anything just pure analog circuits

Great skill!

Excellent, I recomend to buy the Peak Atlas DCA75 Pro, this is a very powerful component tester.

amazing as always. loving the drum and bass btw

My parents have a s940h. It's already been in the shop once for a faulty wifi and Bluetooth module. But now again it's failing. Sometimes it won't connect sometimes u can't even find the unit when you search for Bluetooth devices to pair. Onkyo also had a similar issue as well. It seems these units nowadays aren't meant to last long anymore. All other functions work fine. It has great sound too and plenty of power to back it up. I ran a set of infinity crescendo cs-3009 floor speakers on it and they sounded great.

Thank You So Much.

Nice work! Thanks!

Exellent trouble shooting. I love your youtube video.

Look how light is that aluminum heatsink in comparison to older models - The manufacfurers are cuting costs as low as possible

Great video, was this transistor in a power regulator circuit? It looks like it was connected to a half wave rectifier circuit with a 16 volt filter cap

Could that bad transistor have been discovered with a multimeter opposed to your transistor tester?

🐨APU I dropped a like..

Where do you find the schematics for these old monsters?... I never have any luck so they go to the landfill

hello great video , i have similar issue , with X2700h , my reciever working sometimes 1 minute , sometime 30-40min and turn off in protect . When i go in developer mod say “DC” is displayed (DC output of the power amplifier is abnormal. If the power is turned on during this abnormality, protection is activated after around 6 seconds and the power is turned off) is it the same problem ?

Nice fix. I was wondering about the resolder of all the pins. Did you use lead free replacement? I've found the lead free stuff doesn't preform the same when redoing a joint and always have to resort to getting rid of as much of the original solder as possible and by that stage, it's then just easier to put back leaded solder. Mixing leaded and lead free doesn't seem to work for me either for long term.

Would these good readings be the same on all amps?

I have a different model:avr-710w but it has the same problem I will check if it will be the same I have a different model but it has the same problem I will check if it will be the same .
