Done.
Dave, the 4013 flip flop is being wired as a zero crossing detector. When you press the button on the remote the 4013 waits for the AC to reach zero crossing before switching on the mains transformer.
Any idea if this is the same fix for the TSR-8750?
fuck just through out my old one for the same issue tested and tested and couldn't figure out and my "new" rx-v557 doing the same thin might have a go at replacing it see if it solves the issue
I have Rx-A2010 no sound issue as well. I have corrosion or burn on the board where blue and white wires feed from Transformer. Any ideas or help is much appreciated. Thank you
brilliant. you actually helped a great deal in saving me to carry the whole thing to the repair shop. Took the daughter board out of the amp with the C405 i bought and went to the shop and had it replaced
You made my day
Bless
i replaced it…that wasnt it
My Rx-V667 was shutting down during watching the WC final 🙁
I've replaced the 2 caps 22n 630V but the fault is somewhere else, I suspect that it related to the switching IC because the transformer gives no AC voltages to the rectifier diodes which produces the +5V for the rest of digital boards. Too difficult to investigate further, so I tried with a solution of feeding external +5V power to the rectifier output and it's working.
Im so tired of hearing you say that if you normally worked on this you would’ve. Found the problem.
JESUS CHRIST WHO GIVES A SHIT FOR 15 minutes youve said absolutely NOTHING. YOUR MAKING CHILDISH SOUNDS BC IT WAS RIGHT IN FRONT OF YOU AND YOU FIDNT SEE IT THRN YOU START TO GET INTO EXPLAINING SOMETHING-THEN BAIL OUT BC IT WOUJD TAKE TOO LONG.

I was given a broken yamaha rx-v3800 it wouldn't power on. A visit to jaycar and a 70c 223k cap later I fixed it. Bought some $100 jamo speakers. Now I have a 7.1 home theatre setup that sounds awesome.
Worked for RX-V861 great !!!!! Thanks a lot!!!!!😅
This solved my problem too. And I even had the exact replacement capacitor in my parts tray! Thanks for saving me $$$
Just fixed my 757 with this. I'm grateful for the Wizards of the internet.
That Lidl soldering iron has paid for herself.
Hey bro. I have yamaha RX-A740. I can't see too find the C405 on mine… Any idea which one in this amp?
My Yamaha htr-5890 receiver keeps shutting off after about a half hour of use. I think it is over heating. What components do you think could be bad ?….Maybe a capacitor or something else ?
Love the way you work i really enjoyed
please service center address
Everyone knew this 🤣
Hi, I am tring to repair a receiver yamaha that when I press the buttons the function selected is wrong. I think to replace the processor but I am not sure if there are any program recorded in the CI by the manufacturer. Do you know if is possible to replace for one from chinese market or need be requested to manufaturer?
Hi nice video well can u do video on yahama RX V 661 no power
Awesome video, but did have a question, I have the same model receiver but the capacitor in question is labeled in mine as 473K 400FI , it is the exact same size as the 223K capacitor as well, wondering if there was an update to this capacitor along the way, and also if you had any resource on where to obtain said capacitor. Thanks for any help!
Some diodes D404,D405 and D406
Hi, can you show me the value of component R419 and C406. Thanks
Wish me luck, first time for every thing, better than scrapping , ps need to get part
