Yamaha RX V775 No sound !!FIXED!!

The no sound is common issue with Yamaha RX series amplifiers. This issue is caused by a faulty DSP chip. If the chip does not work at all you will need a new chip. But most likely the chip just has a bad connection.
sympton: usually you get sound once the chip is warmed up
Reflowing the chip will fix the issue and you will get sound back.
This instruction will fix all the RX series amplifiers with the DSP chip.
The thing in the tube is soldering flux. It helps to make the solder tin flow. I have a tube of some cheap stuff made in china. The brand is Hanwuyou advanced metals tech inc. Flux type NC-559-ASM. Almost any soldering flux in a tube can be used. The best would be Amtech 559 rosin flux.
For cleaning I used IPA (iso propral alcohol), if you do not have some you can use zippo petrol or any other electronic cleaner.

Hi, I have the same problem in my Yamaha AV 10 30 Aventage... Would it work as well?!@@modernfix1

[@marks_02]

This worked for me - I fixed my Yamah RX-A1020. Use Flux and a Heat Gun like in the video. Get a laser-pointer thermometer to check the temp. After the successful fix, you will want to use thermal paste to glue a small heatsink onto that DSP chip. Buy the heatsink and paste in advance. 1. Hook up a speaker to the stereo to test that it is working or not. 2. Open the lid. 3. Heat the DSP chip to about 150-200 degrees F to confirm that sound comes back and that is your problem. 4. Unhook all electricity 5. put a small amount of flux all around outside of chip. 6. heat the perimeter of the chip (the flux) to about 350 degrees F, as evenly as possible. I heard a couple small "pops" while I did this. Check the temp often and don't get too hot too quick. The entire process takes about 5 mins. or less. 7. Wait for the chip to cool back down. Do NOT touch the chip or wipe it clean while it is still hot. 8. After it cools, turn on the power and check. I couldn't believe it, but mine actually works now. 9. Recommended step 9 - glue a heatsink to the top of the chip to help manage the heat in the future so that this fix will last longer. The DSP chip is a little less that 1" inch square. I'm not sure 100% sure of the max heatsink size - around 22mm I think. Google how to apply heatsinks.

[@modernfix1]

What was the difference in heat on the chip after you put the heat sink on? And how hot was the chip before the heat sink?

[@marks_02]

I don’t have any measurements of how hot the chip gets after hours of normal use. Then I don’t have any measurements of how hot the chip gets with the heat sink. Everything is based on the assumption that thermal expansion and contraction caused the original issue, and on the assumption that a heat sink will keep it a little bit cooler so that it expands and contracts less.

[@modernfix1]

@@marks_02 Yes you are right. Thank you for your excelent comments.

[@italiwoods]

Thanks for the tips. I will follow your first tip to confirm it´s the same problem, if this works I will definetely add a heatsink just like you said. I had noticed the receiver (HTR-2064) does produce a lot of heat that comes out from the top of the unit, I can only imagine during some extreme hot summer days...

[@modernfix1]

@@italiwoods Yes, heat is the killer of electronics. Most of the heat comes from the analog side of the board (amplifier part). Order some thermal pad or paste to put under the heat sink like you would on a computer processor. You may also consider changing the thermal paste under the power mosfets. Those you can find screwed in to the heat sink on the front side. Those produce lots of heat.

[@modernfix1]

Good idea that tape. Remember to let the area cool down before removing the tape otherwise you may rip of some components. You may try adding a cooler to the chip or a heat sink. That will make the repair last longer. Thank you for the comment.

[@Kumputer]

@@modernfix1 How much heat is generated by the DSP chip directly? Because if most of the heat comes from the power supply or other components, I'd imagine a heatsink wouldn't really help in this case unless you have airflow to vent the chassis. Otherwise wouldn't it just stay at roughly the same ambient temperature?

[@modernfix1]

@@Kumputer Very good point. Good airflow is the best thing that you can do. I have not tested how much actual chip generates heat. I have seen cases where people have added a normal computer case fan since they are low rpm and do not make a lot of noise. You can mount them outside of the case and get the power from a usb power adapter or rig a 5v power supply to them.

[@Kumputer]

Maybe my feeling of accomplishment is premature. Seems like the chip is already starting to go bad again. Sound is cutting out frequently, and the speaker icons disappear starting today. Considering ordering a new chip, though the replacement looks a bit more difficult.

[@modernfix1]

@@Kumputer yes, this is not permanent fix. I would say more like a fix so that you have time to order the new chip. Some people have luck and this last for years and other break down faster.

My RX-830 have same problem. I hope its works

[@fceuropa]

This is brilliant. Even just the hair dryer heat up test step seemed to fix my unit with now only the odd drop out. So I am looking to do the full fix, but my local electronics store only has a flux pen (like a highlighter) or a lead solder paste in a syringe which is actually what the store owner was suggesting would be best for the job. He reckoned the suspended solder would get pulled into the gaps and do a better job of filling the gaps than just flux alone. Any thoughts on solder paste for this kind of application? Or should I be just getting flux used here?

[@modernfix1]

Solder paste is brilliant stuff, I like to use when soldering smd components back on. You can use solder paste and the heat will suck the solder to metal. Good thing when using it you need a lot less heat and no danger knocking of other components. But be warned if you use too much you will run in to the risk of creating bridges between other components and bridging other pins together. This will cause a short and may break your device. This is a case where less is more. In any case this is a good idea, please let me know how it worked. P.S. it is a good idea to have a good soldering iron if you have any bridges.

[@fceuropa]

@@modernfix1 thanks for info, tips and encouragement. Can I double check one thing? Your video mentions +410 deg Celcius but others in the comments are talking about 400 F . Are you sure the temp should be +410 Celcius? Did you mean Fahrenheit? Seems crazy hot.

[@modernfix1]

@@fceuropa I am in the EU so use celcius and all my equipment is in celsius. I do apologize if I have used incorrect terms. English is not my native language. When you are dealing with solder and electronics you need to use crazy hot temperatures. As odd as it sounds it will cause less damage since you will use less time and time is the crucial thing here. You will also have understand that PCB's and other components will take the heat also. e.g. if you have multilayer PCB the all the layers contains coppor and it will spread the heat everywhere. Normal solder that does not contain aluminum or lead has a very high melting point 350-380celsius. So you need to apply lots of heat to get the solder to melt fast. Their are lots of different types of solder and most industrial use solder has a very high melting point. Did this help you to understand why you need crazy hot temperatures.

[@fceuropa]

@@modernfix1 awesome, thanks for the confirmation and the extra info. And no need for apologies as it seems like you had the correct terms all along. I better go buy that heat gun as it sounds like my hairdryer is not going to cut it for this task :)

[@modernfix1]

No you cannot use wd-40 because flux is used to make the solder melt better and make a solid connection. WD-40 can be used near electronic device because it does not conduct electricity but not to this purpose. Name come from water displacing formula 40.

Will also just try running through sound while heating the dsp chip to see if thats actually even the issue - I would think it would be - Many thanks

[@modernfix1]

Sorry to heard that. If it is the DSP chip you should be missing to logo on the startup like in my video. The problem with inaccurate heatguns is that they may run too hot. Too much heat will damage the chip and may cause other issue such as solder causing bridges to other components and causing them to short out. This is why you should always use a hot air soldering gun because the temperature is precise heat and you can also control the air flow. Cleaning up of the flux is important because there is some many different type of flux some you can leave and others you must clean. Take a look at your flux what does it say about cleaning. Here is a good tread about the issue www.avsforum.com/threads/the-official-yamaha-rx-v673-thread-7-2-channel-network-avr.1408245/page-203 I actually bought a new chip D80YK113DPTP400 for my amplifier.

That is not an easy fix lol.. A much easier fix would be to just blow on it with a heat gun lol

This heating up like I did was just a temporal fix. With me it lasted for 7months and then it failed again. Some have reported even longer time for this fix. Maybe more cooling for the chip with a heatsink would help. But a new chip from aliexpress was needed for a more permanent fix.
