This is an excellent tutorial. You have helped to identify the exact same problem that I have. No voltage at the pads. I'm an electrician and not an electronics guy, so removing and resoldering are beyond my skillset.I am hoping to find someone locally (Las Cruces,NM) who is capable to replace that chip. You have hopefully saved the tech some troubleshooting time and me a few bucks! Thank you for a very educational video!

Thank you! I love that you let us follow every step of the repair. I have to say, though, I don't think I will bother repairing my unit, but I just had to stop by to extend my great appreciation for your care and repair on this subject. My best to you in all that you do!

Excellent solder job my friend! I was surprised to hear you say that it was challenging for you, you are a natural! It seems pretty crucial to use a good solder paste and hot air station. I hope to add tools like that to my kit someday, cant avoid surface mount components for much longer.

Thank you very much for your video, it helped me find out what was wrong with my wct290, I practically gave it up for lost and I was thinking of throwing it away, but I decided to buy the mosfet and replaced it, now I continue enjoying my sound bar .

Thank you so much for sharing this video. I fixed my sub that didn t work and i experienced the same failure. Thank you so much from Italy 😉

Comunque è una vergogna si rompono tutti questi subwoofer, se fosse una casa seria, Sony, dovrebbe ritirare e sostituire gratuitamente questi apparecchi. Anche il mio è rotto e sembrerebbe lo stesso problema, ma logicamente non avendo tutti questi strumenti rischierei solo di rovinare di più le componenti. Come sei riuscito a sostituire il chip? Hai skill in merito o hai solo tentato?

Good video man, congrats. That helps me to find the error on my exact same Subwoofer. I don’t know if i’m skillful enough to perform this, but i am going to do it anyways 😂.

Thank you. I have the same sound bar and the subwoofer went out, idk when. Took it apart, googled the mains PCB PN# and it brought me to your video. Sure enough, check that 3.3V TP and no voltage. Got the 18V. Problem is I don't have a heat gun. Plenty of soldering at this size of SMD. 🤔

My friend Mr Nair (86) a retd. scientist from Hindustan Antibiotics Ltd Pune India, & recd. this HT CT 290 system as a gift from his son at Seattle USA an year back. All of a sudden the woofer stopped on a fine day when there was some voltage fluctuations. This S/w was taken to a local authorised service centre. They charged Rs.150/- for checking. And quoted Rs. 2500/- as repairs charges. We were not happy at this. And refused. We now plan to take it to a local expert, to save heavy servicing charges. ( 60% saving is expected) Your guiding tutorial is of a definite help in resolving this. Thank you for that. Also the videography is of equally better quality. Very good illustration also. This video creates hopes and might be a perpetual help to the buyers of this substandard system bearing a big brand name. Thanks again

Thanks for sharing this. He helped me fix the sub myself. However, after replacing the TPS54334, I couldn't connect to the sound bar, and there was a situation where the sub LED just flashed red. The cause is that the cable "AWM 21107" connected to the Bluetooth module is bad. After replacing the cable, it returned to normal. I want to share so that people can have more solutions

Awesome job. So glad it was helpful. Thanks for your kind comment!

I have the exact surround sound system and last week my subwoofer stopped working. I am by no means an expert on electronics but I can fake it pretty well. Anyway, after looking at the pcb and not noticing any visible issues, I turned to the trusty KZreads and the first video that came up was this one. So after watching this I ordered the chip, a hot air station and solder paste. The chip came in today and I couldn’t wait to try replacing the chip. I’ve never used a hot air station and I need A LOT more practice, but after watching this video I was somewhat confident I could do this. Well after melting the chip, tearing off 3 pins, lifting one trace off of the board and still having that back of the chip soldered on, I eventually got the chip removed. I cleaned up all the flux and soldered the new chip on. And as the gentleman in the video stated he wouldn’t have been able to do this without solder paste, he is 100% correct. I wasn’t very hopeful that it worked but to my surprise, it worked. So Mr. TTS without this video I would have just gone and bought a new system. So I can not thank you enough for helping me fix my subwoofer and for saving me $300. The chip cost nothing compared to having to buy a new system.

Awesome job. Surface mount devices are a whole different beast for sure. With the smaller components all around it makes the job even tougher. For years I enjoyed learning electronics, but thought SMD devices were off limits for me. I would only work with through hole devices for the majority of repairs for years. One thing I finally learned is the more we do it, the easier it gets. The hot air station is a life saver. If that was your first time using the hot air station you did great. Thanks so much for your kind comment and so glad it helped.

I did SMT soldering for years at different companies in Ottawa Ca and let me tell that chip is easy. Don't be afraid to get the chip hot, taping it off was a good idea, the hot air will blow of the smaller components around it. But don't try to pull it off before the solder has melted, you will pull the traces off, it wil come off with no force at all. The ones that are a pain are ones with huge heatsinks attached, we had giant 200w iron for those.

Love your work. Interesting that on such a small chip, heatsink solder pad is used to draw heat. I'm thinking that's probably the issue.... heat is not being dissipated efficiently. Gluing a piece of aluminum foil might do the trick as long as it doesn't touch other components' terminations. This subwoofer hadn't been in a market that long 5-6 years. Any thing that doesn't last 10 years isn't a well engineered product in my opinion.

That's not great. If your lucky you can clean up the board well and replace the cap and be back in business. One things to make sure of is that you clean the Board extremely well with high percentage IPA or plastic safe contact cleaner so you don't have bad corrosion later from the cap electrolyte.

Hey. Nice and clean work. My question is does it matter which chip is needed? my chip is: 54334 TI 82A P2E1G3 i found alixpres this chip: 54334 TI 98A P1HHG3 thanks.

I believe it will work fine. Most components with 54334 are very similar in spec. I would compare it to make sure though.

Where can I buy the chip

I have links in the video description. The eBay link is most likely long gone. The Newark and even the Amazon link is most likely still good.

Could i send you my board/back to fix?

I wish I had time, I do get asked this often. I do not have a repair service at this time. I work full time+ in a Industrial job and try to have time to edit videos to post. I try to help by posting what I have learned and sharing that best I can. Best of luck to you with yours!

Hello good day! I need help with this equipment, the client did not bring the bar, only the subwoofer, when checking, detected an integrated 8-pin shorted TPS54334, I changed it by installing the new one, and that's it, the equipment gave a signal of life, green led flashing and red (I said This is ok) but there is an additional problem, that it does not link with the bar. I actually did all the tests for the safe link. I disassembled the subwoofer and I do not see anything strange. The voltage reaches the bluetooth card. Change some capacitors. I have come to think that the piece of Replacement does not work, I have doubts when I turn on the led it goes from red to the link link link it changes to flashing green then to red. I thank you if you can help me, I do not give up easily.

I know what you mean. It's hard to give up on a repair. I have only had the one issue so if you are getting the 3.3V rail I would think your chip is most likely ok now? I have not had issues with the Bluetooth board/module but sounds possible.

Я тоже столкнулся с такой же проблемой. После замены чипа световой индикатор работает, но связи сабвуфера со звуковой панелью нет. Сабвуфер понимает что он в поиске звуковой панелью, так как режим работы светодиода меняется, но подключение не происходит. Любые идеи?

Question. I don't think I'm skilled enough to do this and I don't have the tools. Is it possible to bridge two points so it's always on. Would that work? Thanks.

Well it's actually a DC-DC converter chip that is faulty so it's missing the low voltage supply. It would need a supply on that low voltage rail.

Hi Scott, So glad you find these things interesting. I do have many links down in the video descriptions of tools and items I use myself and find helpful. I also have a small Facebook group to try and help when people ask questions and we can share pdf and other docs etc. there as well. As far as schematics, they are almost non existent these days and it makes it much more challenging for sure so we share what we can as we learn together. If you have any questions that I can help you with, feel free to post on the Facebook group "On The Bench" also my email is thriftytoolshed@gmail.com I wish you the best in learning it is super fun and I have enjoyed learning how things work all my life.

Me too - I'm hoping to make an experiment out of it, and see if I can repurpose the subwoofer by running wires to it. Can't find anyone that's ever tried that, or how to easily trace the wires to tap them into the input where the wireless signal would come in?

I have the 660 sub

Has anyone here been able to successfully receive the chip they ordered on newark, Amazon, or eBay?

I called Sony customer support regarding this issue, with my device being just over a year old they told me to go pound sand. It looks like Sony is now producing garbage and is not taking any responsibility for the pre-mature failure of there products. Apparently I will need to start warming up to Samsung TV's because I will not be buying anything with a Sony logo ever again.
