Great help after a long search what the problem was. Thanks. 👍🏼
I tried everything for my 730, found your video an it worked. Thx!
That is why I still love any vintage gears.
Repairable anytime and anywhere without the need of special tools.
?? You need all kinds of special tools to service a vintage receiver....like say a solder removing gun/tool...meters, scopes, etc, etc
@@markfrost2707 Shut up mo(r)ron you know nothing !!! Be silent !!
Tanks for sharing your knowledge chears from Quetzaltenango.
Those friggin Ti DTS chips. The biggest plague in the Onkyo AV receivers' HDMI boards and many still believe it's the BGA soldering. Nope, it's the chip itself.
You are so correct. TI had a manufacturing plant that got flooded due to bad weather, however production continued with contaminated chip manufacturing process. Some of those DTS/ HDMI PCB's are NLA too so BGA / SMD reflow process may be the only option, then fit heatsinks and fans like I did.
I have the exact same problem with my 10 year old Yamaha RX-V673. Time for a new one I guess :(
It's a shame that affordable repairs is no longer a thing in a world that needs to look after it's resources.
Thanks for a great video NorCal715
You make an excellent point. With all the environmental concern these days, why would they make electronic devices so hard to repair?
@@FeedScrn They want you to buy new products. Profit before planet
thanks for making this video
Mine just started doing this as well. Pushing Pure Direct does not result in sound, just letting it sit for awhile. Mine is an RX-A750. Nice to know these need to be replaced every 7 years or so, or deal with the warming up problem. What a royal PIA.
Exact same here with the flagship rxa3010. Very disappointed this happens to a high end receiver. I'll get me a Denon again, never had problems with that
My denon didn't last nearly as long as my Yamaha. But now having this problem too. Denon went kaput in less than 3 years.
check the ADC
I believe my own RX-A720 has started doing this.
Mine takes around 5-10mins to start to hear sound coming out of it. Pure Direct makes no difference on mine though still no sound. Once sound comes out of it it's fine.
I'll either have to leave it on or get rid of it and start the research of finding a similar style amp without these issues.
Thanks for the informative video.
My Rx-A550 started this way. Went on for about 4-5 months. Now the sound won't come on regardless of how long I leave it on
I got one a few years ago, not sure if the same model.. but it wouldn’t turn on. The power supply board had a blown fuse.. I think water or pop shorted out a few channels.. I guess I could de-solder the shorted out ones and try it.
I ask about a clock Crystal as I had a Denon recently, stuck in over current mode no shorts on the amplifier though. The DSP Ic pretty similar part to this one had some weird readings on its local Mlccs, when heated at 440 the Ic would work and the amp would turn on. I decided to heat the whole local area and narrowed it down to a 22mhz clock Crystal near by, when heated would work when cooled it would die. Replaced it and the amp lives have a check around before writing it off.
This sounds more like it, in the service manual it should give an example of what the clock should show you when measured from a certain pin on the device to an oscilloscope.
Reflow is the solution.
Did on my Yamaha RX-A3020. there is 2 identical DSP-chips inside.
What is reflow and how is it done? Many thanks.
I have two RX-A830's one has the same issue. The other has been going strong since new.
It's definitely a IC issue not a BGA issue etc,
The only fix is a new chip. I did manage to get the software online. To programme it through USB. But getting the chip isn't easy. A authorized dealer near me has them. But refuses to sell to public.
These will be the last Yamaha receivers I'll own. And I'll be avoiding those DSP chips.
We ended up pulling them off the shelf at work. We just had so much comebacks. And the repair was a replacement board which conveniently stopped being available after the warrantees expired.
fuckkkkkk
Hi bro, had the same problem with an Onkyo from 2011, I poured flux around the chip and blowed some hot air till flux boiled. I throughly cleaned up and added a thermal aluminum to dissipate heat, plus a fan connected to the +12V rail… still works fine. Other than that, sue Texas Instruments 🤣
Awesome.There were a large amount of faulty DTS chips made by TI..... I did the same thing except I have a thermal conductive silicone pad from a computer fitted to the DTS chip PCB underside and then used neutral cure high strength RTV sealant to secure the heat-sink on the edges to the PCB. I have added four 12V DC brush-less fans powered by external 12V power supply to the top of the amp so the suck hot air out all the time while amp is powered on. Oversized high mass copper / Aluminium heatsink on top of DTS chip also !! Grazie, e Salute. Giuseppe.
Lots of problems with their DLP chips in the old TVs as well.
It's such a large package and i wonder if the (significant) thermal expansion/contraction cycles of a typical class ab receiver get mechanically amplified through the large area chip package, and eventually stress fracture the die (or its pin wire bindings) .
This IC does have a thermal pad on the bottom approximately 3/4 in square that is soldered to the board for heat dissipation, Obviously it was not enough. Possibly a finned heat on the top would help if it has not failed already.
@@norcal715 makes sense .
the soldered pad probably further contributes to an overly rigid situation: a giant square of chip encasing epoxy that has thermal expansion 2to3 times that of the copper pad and the pcb, and 4 to 5 times that of the silicon die . years of baking hot cycles eventually take their toll
Had this problem on my Yamaha 720. It would pop and crackle through the speakers for maybe 5 minutes then work. I got worried about the speakers so I just bought a yamaha A4A. So glad I did. Niiiiiiice reciever. Anyways I am going to try and fix the 720 just for fun starting with a reflow.
What is reflow and how is it done? Many thanks.
@@quadimus reflowing the solder on the chip
Thank you so much, I have the 675, I have just tested and your absolutely bang on right. I'm guessing my receiver if now more or less scrap?
Check the DAC i believe the older ones used the DAC to split / create all the channels to the surround inputs on the amp section. the dsp may only do the effects and give one digital out and one regular direct output however the dsp may have something to do with activating the speaker protection relays, unless it's the processor that controls those, i'm not sure on that one and also check the clock signal with a scope if possible, some suggest changing the crystal. Check small caps around the IC's
Why bin it? For stereo it sounds great in pure direct. I have a few different Aventage receivers and if i had this on one id just put it on a 2-channel setup and always use pure direct.
avr1912 power on but no sound for speakers but subwoofer is working. When I check the digital board BDV3002 ic is produce too much of heat. but that ic is not related to sound. according to schematic diagram that ic is a HDMI switcher. do you have any suggestions. I'm from Sri Lanka
try securing something that generates heat like a resister or a small bulb? on top of it maybe or is it needs extrema heat in order to work
Exact same model of receiver, worked fine for years now sound is not working just as described. It comes back after a lot of cursing and swapping inputs, but from this video I suspect it's just because it had time to warm up. I'll see if leaving it on and no fiddling brings the sound back, but likely time for a new receiver...
Could be a cold or cracked solder joint on one of the chips pins. Heat expands, cold contracts.
I have an RX-1010 that had the same issue. I replaced the chip and that fixed it. Didn't have to program anything.
En cuanto te salio ?
Bro, where did you purchase the ic
I fixed the problem with a led loop over both chips but we'll see how long it lasts considering someone wrote that the temperature will increase......
my RX-V661 just started an issue today. After it being stored in a box for 4 years due to house renos, i finally hooked everything back up. It worked for about 45 mins then the front and rear speakers stopped working............. center channel and sub work fine.............. any guesses?
Hello sir i have yamaha rx-v457 when direct same as yours its working fine. But when i switch to 5.1 channel hall effect prologic mode the sound is massive distorted.. crackling sound.. may i know if my problem is DSP chip i.c? I want to replace it but i want some pretty advise sir if it possible dsp ic because it is a little bit pricey. Thank u so much
Is there a local clock Crystal for these Ics ?
Try to reflow the pin, or repeal the chip, and resolder it back. Probably there is maybe micro fracture some where, ether on the track or on the bond wire inside the chip.
I did try to reflow the IC on a different unit. It made it worse.
I have a Yamaha RX-A2A Receiver, it stopped ringing, it also says error when updating firmware error 002000 it works with pure direct, but it doesn't make any sound the other way, it just says decoder off.
Ok... Any suggestions for opposite issue. I have sound but no video rx-v671. HDMI out not working. Sound works from HDMI input.
I have a v473, and mine is usually in 7.1 mode and when I start it up I get nothing. After 5 minutes or so it comes in, cuts out for a minute and eventually it’ll stay on. Sound like the same issue ?
Hi sir how's u i have yamaha rx a860 the problem is the electricity is running in the body of the receiver when i turn it on and i put the tester on the body it's fully lit up so can you please tell me how to fix it
My new/secondhand Yamaha 3060 I recently installed has started to intermittently cut out when playing CDs and I wonder if this is why as it only seems to happen shortly after starting to play. It plays fine mostly but suddenly stops for 2-4 seconds (shows "Decoder Off") then resumes. Most annoying.
my brand new 30d old receiver broke, 6 days out of Amazon return window... I only used it for a few days. They are selling these for $1,000.00 and they break after a few minutes of loud volume.
My 720 just started to do the No Sound problem. So we need a very small heat source?! So I put a 60W bulb on top of it, it's working!! Now to check the actual temp an go from there
Bro teac 8800 av receiver only front lift right chanels not sound bro centre back sorrounding good work what a problem???
Bravo......put heater on chip......with controler temp......cheers
Thanks to NorCal715 for the original post.
I'll summerise, i'm a broadcast tech of 40 years in Oz.
Had the same Yam 720 as in the original clip with the identical fault exactly.
A couple of times someone posted you should reflow the chip that's in there. (Thanks for that).
Mine was very close to getting binned, so some Flux and a $30.00 hot air iron from Jaycar.
Yippee. All good (Even when it cooled down, lets hope it staays that way).
Also probably most of you who posted about not getting audio in the direct mode, that is sort of right, no one will get it if they are going in at HDMI or Optical, With the chip failing, Direct only worked for Unbalanced R & L inputs.
Thanks again.
I have the yamaha a4a. I turn it off with my roku but about 1-2min later the AV turns back on for about 20seconds then shuts itself off again. Kinda like it thinks I turned on the roku or tv but I don't. Any ideas?
I have the same problem with my 675. The DSP chip only works at temperatures above 40°C but it never got higher than 35C°. So I put a polyester heating foil on the DSP which gets up to 50°C and needs 12V. It worked like charm for about 3 month and then the DSP acted up again. Minimum temp is now > 60°C.... ;-((
Very soon the chip needs 80 degrees to work.
I think I probably have this problem with a RX-V675.
Going, going and gone. That is the problem coming.
I have a 820 at warm up I hear a power click @ 10 minutes. Pure direct has no effect, blogs suggest protection capacitors or resisters
My HTR 3066 Showing "DC PRT : 253H" error. Some times it's shows 249h, 252h errors. And shutdown after 3-4 seconds. What are the possible problems.. is it a capacitor leakage or any short ?
I am having constant crackling from all channels regardless of mode on my A2020. Any ideas what could be causing this ?
Any suggestions for high quality used receivers that are under 500$ ?
Anyone have a source on the chips themselves? Or know someone i can send my board to, to have fixed?
Is the dsp chip in a RX-V863 the same or possible use as a substitute for the RX-A3020?
I’ve been noticing a similar, but slightly different issue with my RX-V385 that I bought a little under a year ago. For the past month or so that whenever I play a Blu-Ray through my Marantz UD5007 the movie will start with what sounds like crystal clear music and sound effects, but once people begin to speak it sounds like their mouths are covered with a wrestling mat, muffled to the point of near nothingness. This issue seems to be rectified by simply “opening up” the sound a bit, basically pumping the volume up until the bubble pops and you can hear everything just fine. Is there any way to correct this issue without resorting to this kind of cheap hack that I do? FWIW it’s only seemed to occur in the time since I’ve added an RCA cable to the back of the Marantz for AV usage, but I’m always watching a Blu-Ray on HDMI1 so i’m not sure if that’s material in this equation or not.
Check the speaker relay contacts, that can cause muffled high resistance connections until enough current flows to "weld" the contacts together. That would be my first go-to.
Hi My rx-v467 avr doesn't have the speaker icon on the display screen. Is it the chip causes this problem?
I’m having the same issue with my RX-A1020. Can this be fixed without just trashing it and buying a new one?
Some days ago I was working in one Yamaha receiver like this.
I found the audio signal was correct in any amplifier input, no sound at all because the mute is active all the time.
Mute control fail from DSP, my solución was desconect the mute and everything work perfect.
This is my case.
How you disconnect the mute?..thanks
@@bentotlasala3113 I remove the mute transistors in each amplifier input.
Is it possibly a bad solder conn on one of the leg, maybe by heating the chip it expands the chip enough to cause the leg to contact......reflow the legs..???
Sorry, I was typing when the caption about the reflow came up...
Anyway, best wishes Steve.
You are right! This problem is exactly that.
I do have a Yamaha RX-V685 receiver with no soud problem even in direct mode. Know somebody where I can find a DSP chip Texas Instruments YF-92AN09W for this unit? Best regards.
If you get a replacement DSP IC, maybe you can just destroy the center, and lay the new one over the old contacts and solder it on like that. That might be easier than messing with all of those pins the 'normal' way.
Others in here are saying that it's just a cold solder joint connection, and all you need to do is a reflow with a heat gun. Dunno. Guess it's worth trying (first).
you can take some 2mm or 3mm copper wire and form it into a square that covers the pins of the ic. Then use one or two soldering irons after adding solder all along the wire and legs, the heat travels around the wire and the ic should come loose after around 30 seconds at 400C. 2 irons will help to melt all 4 sides quicker if you are careful.
@@izzzzzz6 - I used a heat gun on it. If you do, use it Carefully. If you are looking for something visible to happen, you used too much heat and the circuit is destroyed. // Tip- don't use the heat gun right after canned air is used... too much moisture. // I ended up fixing two receivers.
Are you sure that this DSP chip has a programmable memory?
Try to replace the DSP chip without programming the DSP chip.
You don't have any thing to lose.
put a heater element on it ,like like a xtal oven
I have the RX-V671 and it has just stopped outputting sound to the speakers. Weirdly if I connect the YPAD MIC the unit runs through all its measurements and sounds come out the speaker. Perhaps it's a different driver chip that's used. The pure direct didn't make any difference.
Update: I found out how to factory reset the unit, and that has fixed the issue. If interested, it's: turn unit off, then while holding the 'straight' button on, turn the unit back on. The advanced menu appears, where you can choose to format the device. Then turn off and back on and problem solved.
I was thinking about purchasing the rx v 3020 do you know if this model has that issue haven't seen or read anything yet
if it works, add heatsink and fan mods asap to prolong DTS chip / amplifier life.
@@peppino5413 mine only works once heated up - would a reflow - then - adding a heatsink work?
RX-V673. Similar issue as others described here. I have no sound until it warms up, even in Pure Direct mode, then as it warms the sound pops in and out very crackly a bit before the sound starts working normally. Does this condiion continue to worsen and take longer and longer for the sound to return, then eventually stop altogether?
Same here as it heats up , sound comes on. Chip issue alright. I love my Yamaha RX 720. Wonder if I can get repaired in Canada 🇨🇦
I have the Yamaha RX-V1800 natural sound av reciever.. Shuts off after playing a few minutes or so but gives an error on the screen to check speaker wires. This was my brother's He passed young it's very sentimental. Need a fix if anyone can help. Thanks 😊
Does it have an impedance switch on the rear? These can become oxidised and create a higher resistance, could be worth checking as it might cause a fault to show. I wonder if one of the main amplifier transistors or something has a bad connection. Do a good check to make sure there are no small strands of wire bridging the speaker connections and probably most importantly. test the speakers resistance to check they are between the spec. probably between 6ohm and 8ohm
My sound just went out yesterday no reason at all. No sound from anything. I have an RX-V477. I’ll have to try this with a heat gun. We should be able to repair these darn it. Someone should sell replacement chips man. But I’ll have to bow to the consumer gods and buy a new one.
I used a heat gun to heat the DSP and sound came back. I plugged everything back in and still have sound. Not totally dead yet.
Hello, I have the RX V573 with a similar audio problem,my heat gun has a much wider nozzle
I have a RX-V659 can't get any sound at all
with tnm 5000 programmer maybe programming the dsp chip
same also with my yamaha rx v679.......🥲
I have same problem on my Yamaha RX-A 3020 so I end up changing new DSP chip.So dear to solve your problem you need to replace DSP chip.
Just curious, where did you get the IC?
@@norcal715 it is the D2S daughter board PCB assembly fitted to a small removable PCB from the main HDMI PCB. I know because I have two of these RX-A3000 and have fixed them myself being an authorized Yamaha Audio Service Technician. I have added heatsinks and four fans on top of the amplifier too.
@@peppino5413 link to where you can buy this? Mine is doing the same! Thanks
@@peppino5413 Any chance you could make a short video about your solution? There are many people watching their RX-A3000's die an early death and yamaha aren't very helpful!

Mine won’t work in pure direct or enhanced, sometimes it doesn’t detect the speakers and sometimes it detects them and still doesn’t play

What can it be if it don't turn on just turn red light flash
Probably has a speaker power output issue or a power supply issue. Most likely shorted speaker power output Transistors/Drivers, and associated components.
i have the same problem .. but my service partner says now its the "digi board" its 700euro to fix it. i cant belive this shit!
700euro?! u can buy 4 of this whith 700euro lol
sadly its time for a new one :( it was a good receiver
The solution is to replace the D80YK113CPT4 DSP chip with the later D80YK113DPTP4
Do you have more information, or is as simple as replacing the IC with a different version? Does it require any programming?
@@norcal715 no once you fit the replacement u just need to do firmware update thru USB should work
My issue with this receiver is that it delivers voices at a very low volume--everything else fine, but it's like listening to a live band with the singer's mike turned off. Anyone else have this problem?
Vocals are normally delivered the the center channel speaker. I the center channel working correctly? Try a factory/default reset to see if it helps.
@@norcal715 Thanks! I'll give it a try. By the way, when I push the Direct button, the voices are fine, but only on two speakers.
Yes I’m having this exact problem, I have a V385 yahama and it’s been doing this for about a month. It’s only really happening with my HDMI1 blu-ray connection. I’ll throw a movie on and all the music/sound effects will sound fine but voices are impossible to make out. Swapping sound programs works as well as my trick which is just to pump the volume up until the bubble bursts and you hear everything. I’d like to have a more direct fix for this, but I can’t find anything about it online. All the connections to my speakers are fine (I’ve had that issue before).
dude exactly same reciever and it does the same thing. i have to let it warm up for an hour before its reliable and yes pushing the pure direct button helps but if u just stay away from the button while its warming up it works good. what a bitch right
Well that’s a shame
Yup...same shitty DSP chip problems as the ONKYO crap they made.......same TI chips too.....I'll keep my old Yammy 1992 flagship...HDMI sound is not as good either...
just install a heater on that chip ;)
I was thinking the same thing. Maybe adapt an oven like you would use with with a frequency standard. Then it would be like an old tube receiver. You would start it up and wait for it to heat up before trying to use.
I was thinking the same thing, a small PTC heater set to around 40C, so this would turn on when the unit turns on for say 60 seconds to warm the chip then turn off? did you do this? did it work?
@@benvella4031 no I didn't, but sometimes dumbest ideas are the best answers

Are Yamaha amps the best?
Nothing is the best anymore, compared to the way they used to make them in the 60's and 70's, even the early 80's. Yamaha is a good receiver by todays standards. I have one purchased new 2018 in my own AV system.
