THANK YOU. This worked perfectly for my 10 years old Yamaha RX-V459. I replaced the condensator with 22nF, 630V, which was 0,20€ in local store... Before this "home made" fix I called service and they assumed the cost for fix somewhere between 50-70€...
Thank You so much! My RX-V459 has been working perfectly since 2007. It suddenly stopped turning on last week. I've now replaced that 0.10€ capacitor. And unit works again!
I appreciate all your hard work, you saved me alot of time. I have a RX-V2600 which has a slightly more complicated PS, but the Flip Flop CCT is the same. I measured the .022uf which measured .088uf which is inline with your findings. Once I replaced the cap I tried powering up the Receiver with the PS board not fitted back into the receiver, but with wires connected, only to find the PS didn't work. I soon realised that the Earth Screw terminal on the PS board needed to see a earth.... which it wasn't as the PS board wasn't screwed back in. Once the PS board was correctly mounted all good again. I was surprised to see that most, if not all the Electrolytic Caps on my high end receiver has 85 degree C electro's installed, I would have thought Yamaha would have used higher Temp caps.
Just a thanks from me too - my RX-V1800 was starting to occasionally not power up slightly different power module but same problem. IN this case it was C4 also a 22nf but measureing as 7nF
Thank you, now I can repair my RX-V657..... It does nothing now and everything indicates to the little transformer dat does not switch on, because of the failing capacitor. Many thanks for sharing mate !
works perfectly for me i have put a new condensator 630v 22nf. i started the device and it shut down automaticaly after 1second. in fact don t forget to put back the long screw it connects the pcb to the ground, now it works fine.
Which Screw sir, i have same problem. I have avr450 it had same power supply i replaced the same capacitor after replacing its turn off after 1 second, please help me
Hello many tks for your post : I've had the same problem with R-840 yam module. In this case, Capa was 8,8 n instead 22 n, and limited to 250V, quite the same as the main (235V here in Belgium)... I replace by a 400V one and it's working like a charm... For information, this Capa is marked C13 !!! :-)
Thanks for this mate - has just fixed my RXV650 with the same problem. Cost £0.99 from maplin for the capacitor instead of hundreds for a new unit. Only disappointment is it was verging on a good excuse for an upgrade! Now very difficult to justify. ha ha
Hi there, I have a slightly different problem with a Yamaha RX-V481D. Can you help with what it could be? The amp was little used and only just out of guarantee. When you turn on , there is no sound and to rectify this you put the headphone plug in and back out again, you hear a relay click and it's all working. Then after doing this for say a dozen operations spreadout over some weeks, the amp seemed to work better and didn't need this doing anymore. Then yesterday, it returned back to needing the headphone socket in and out thing doing again, and then once it even clicked off the sound while listening (on for an hour or so) , which it's never done before. Any help appreciated. P.S. the only thing to add is that we don't use the 5.1 channel features on this amp, just 2 speakers connected and select the program: 2 channel stereo.
I could throw around the term of planed obsolesce that many do. But it isn't that. 1/3 failures are due to a good idea at the time, that where new and clever ideas and would need to be ironed out as they fail. In other words lets innovate and R&D at the customers expense in there own home. 2/3 Let's out source as cheep as we can the bit's that are below us, power suplies are so easy a kid can do it, they may pass standards but are shite, but they worked when presented to the buyer. Peace UT :D
Hello, good video, I have one Yamaha RX-V430 and it was in the box for several years, one day I decided to power it on, but it was completely dead. How many voltage should come out from this power supply that you recorded? There is a capacitor on the out put borne it is 104 Q 50V. Should I replace it? I can not find the same capacitor to buy. How can I replace it?
Excellent video and very helpful. I'm about to replace the cap on my board but unsure if this is the problem. Maybe you can confirm? I have a RX-V375 for about 1.5 years. I unplugged it a day to paint the living room and when I plugged it back in there was no more display. Just the red light by the power button. I unplugged everything and did the reset with the straight and power button hold. It does a series of clicks but does not power up or make any thing on the display. So I think its a power source problem. I did electronic repairs in the Navy but always had specs to look at for my checks. This is definitely playing in the dark?
If you just get a red light and clicks then it is probably not this fault as it means the standby circuit is working ok. However you can always try replacing the component as it is not very expensive or difficult to replace.
Hey Tobias, I'm having similar symptoms to your amp. Did you find a solution. I replaced the cap, the relays seem to click in the right order, but no life on the fluro display.
Hello i have a RX-V496 Yamaha amp with the problem of power up and then clicking off and sometimes I get lucky it works for a while The power board is slightly different and has two smaller capacitors at C837 and C842, I was hoping to get your advice on would replacing these solve my problems, and can i test them while still on the board, thanks
Hi, could I ask you for advice to my problem? .........i V459 RX - and I have the following problem. Hang in there, if I want to. Out of all the time and after a few minutes popped up again. But now does not. I don't know what to do. I watched, but you are fine. Thank you for any advice. Sincerely Martin
Hi, can anyone give me a pointer to where to buy a replacement capacitor and the exact one I need, delivery in the UK. I'm not familiar with the different variants/types. Does a 22nf 1kv Film Capacitor PC/HV/S/WF Series PolyPropylene sound correct?
In the Yamaha receiver there is many board which block the audio dsp board volume and reley switch ic micro controller ckt lot chip connect ed so we can't dignos exactly fault where is located professional technical service reqired no luck at same times with you
Dobrý den, mohl bych Vás požádat o radu k mému problému? .......... mám RX-V459 a mám následující problém. Když chci zapnout zařízení, nezapne se. Jindy stačilo vyndat ze zásuvky a po pár minutách zase naskočilo. Ale nyní již nereaguje vůbec. Nevím, co mám udělat. Koukal jsem na pojistky, ale ty jsou v pořádku. Děkuji za každou radu. S pozdravem Martin
I concur. If you left it on standby for a year without that circuit, thats around 25KW Per year and say, I dunno 20pence per KW for arguments sake is £5 per year on standby then say you might have 20 devices consuming the same on standby, costing £100 per year in electricity. I would rather pay for the electricity, than have good equipment become dead in 1 to 10 years due to Eco Nutters not seeing the long term. 95% of these would be binned just for a tired Cap and a new one purchased. Grr. :D
Hi! Thanks for the video! Same problem for me (no switch on). I replaced the capacitor with a new one. Now it opens but then a "click" is heard and switch off again :( Does anyone have any idea what to do?
It is an example of a poorly thought out eco-law designed to make politicians look good. Another example is the removal of lead from solder, which led (and continues to lead to) the rash of BGA processor failures, such as on the Xbox 360/PS3, various nVidia graphics cards, various LCD/plasma TVs etc etc. Wonder how much has been trashed due to bad BGA.

Thanks, this worked on my Yamaha 3800 series Surround Sound Receiver. $1 part from Jaycar and all OK now. Saved me $1500 for a new unit.

Just want to say 'thank you', similar amp similar problem fixed to £3.50 - couldn't buy less than 5 capacitors! Thanks again, good stuff.
Thanks. Replaced the capacitor in the rx-v450 of a friend and worked like a charm.
Thanks a lot for this video ! I've repaired my RVX-3800 unit. (there's no need to remove the power supply board on this unit)
Although the power supply board was a slightly different design, this fix also worked for an Yamaha RX-497. Thanks for the vid!
How come your so clever tom, your a proper Guru !
Just a thanks from me too - my RX-V1800 was starting to occasionally not power up slightly different power module but same problem. IN this case it was C4 also a 22nf but measureing as 7nF

Very important detail. Thanks so much, it helped me a lot
Which Screw sir, i have same problem. I have avr450 it had same power supply i replaced the same capacitor after replacing its turn off after 1 second, please help me
@@TheJaswant82 Hi, did you find the solution?
Thanks so much. I will try for RX-V450 no power on.

Thanks! RX-V661 which had this problem. Fixed easily.
That was my amp! If only I knew how to fix electronics...
Thanks for this mate - has just fixed my RXV650 with the same problem. Cost £0.99 from maplin for the capacitor instead of hundreds for a new unit. Only disappointment is it was verging on a good excuse for an upgrade! Now very difficult to justify. ha ha
Have exact same amp with same problem , thanks , wish me luck , just need to get a capacitor
Thank you for your time my amp now works
thanks for u good work on good knowledge of amplifier. thank you

There's only a little gold in modern electronics like computers, this amplifier didn't have much if any.

I was hoping to see you taking the capacitor out.How does it detach ?Do You use a Soldering iron ?
Yes.
I have Yamaha rx a3070 which is not powering it's on standby mode please what can be the problem?

hello i have a problem about Yamaha rx v-750 amplifier. You not light you can help me?
And another thing, lead pcbs used to go to waste, now theres gold in them, it's changed. on a big scale it is worth while.
Awesome vid. Can please tell me what capacitor you replaced it with. I didnt quite catch what you were saying... Thanks in advance.
22nF 1kV
THANKS !
I am having trouble finding which replacment cipacitor to buy. The code on mine says 473k 400 FI. could does anyone have any idea how to find it?
Hi, can anyone give me a pointer to where to buy a replacement capacitor and the exact one I need, delivery in the UK. I'm not familiar with the different variants/types. Does a 22nf 1kv Film Capacitor PC/HV/S/WF Series PolyPropylene sound correct?
+Graeme Orrin pretty much any type of nonpolar cap with a 22nF capacitance and 800V or higher rating should work fine, those sound ok to me.
Hi how did you came across to trace that ceramic cap was the fault ? can you explain a little bit . Tnx
Plz suggest best quality 5.1 av receiver brand ....
I have this unit too, the unit is power on, everythings work as usual, but no sound come out from the speakers, can you tell me what is the problems??

Dobrý den, mohla by to být tato chyba. Je potřeba vyměnit kondenzátor ukázaný ve videu za nový 22nF/630V ( www.gme.cz/foliovy-kondenzator-cf7-22n-j ).

Replace relay as contacts inside relay may be worn.
Repair sr,x450

You're not a very good teacher,one must show what ones actually doing and looking at,also,not always the capacitor.
what a nasty accent! The horror !
