​@@thespecialist786 The parts from mouser came in, but I'm having issues desoldering the voltage regulators. Any tips?

[@thespecialist786]

@@cinderblue3251You need a hot air gun, also seal the area with high heat tape to protect the area. Soldering iron can not do the job.

[@oscarpozos1]

Hi, very nice video , is this doable with just a soldering iron? Or a hot air gun is needed too?

[@ElizabethBarber-e9b]

All right. Thanks for putting the video up. I have just changed it but it's loud powering on but I've just got the white the Wi-Fi flashing and it's not letting me reset it. Can you help me please?

[@thespecialist786]

Check you have not blow away any resistors next to the chip. Also check power supply.

Do you have a link on where to buy the part?

I replaced both my IC chips (even though only the U1401 was blown) and the unit switches on again, but only for 2 minutes then its dead.. sort of goes into protection mode.. have to wait about 10 minutes and the same happens all over again.. Would you perhaps have an idea what might cause that? It is as if when it gets hot it shuts itself down

[@thespecialist786]

Thankyou for your comment, where did you buy the chips from ? You have bought the wrong ones. Fake most likely or you have heated the chip too long. Buy from here mou.sr/3VR6MtN

@@thespecialist786 Got them on Amazon, as they are not available in South Africa at all. I had someone who fixes electronics put them in. I also asked another KZbinr about the chips, as he also repairs these spesific soundbars, and he gave me the link for Amazon. He gets all his chips from there and never had any issue. If i may ask, what do you mean by "heated too long".. I'm not tech savvy, so maybe i can inform this guy who is fixing my soundbar to just check on that

Hi any guide video on how to desolder and solder those chip :) Thanks

[@juancortez1088]

Does it matter that my chip has a different number than yours, or does your chip with that Serial number work for every 300 bose soundbar??

[@thespecialist786]

Thank you for your comment. Same chip with the same number

[@tusherraihan5671]

Changed both chips. Still no luck …. Any possible solution ?

[@johnbauer1270]

Thanks for the video. I have the same issue, same sound bar. If I need to order a new chip where do I get one from? I searched for the chip numbers from this video, but I couldn't find one with exactly the same numbers. I haven't opened mine up yet so I don't know if the chips are exactly the same. Cheers John

[@thespecialist786]

There are so many fake and different chips around - I will post the link in my Description shortly. Please subscribe to my channel. You need TPS54335 Switching Voltage Regulator 4.5 - 28v Input 3A

Thanks for the great video, I have the same problem as you, on which website can I buy the chip? I live in Germany! Thank you

[@TheUKNZ]

Thank you for doing this video. I have just ordered both chips however neither are showing any burn marks so hoping this is the same fault. :-)

[@thespecialist786]

There is a very good chance that is the issue, but also check the power supply and when installing these chips make sure to use heat tape around as the resistors near by may fly off. Take a before and after photo just to make sure. Also do not heat the chips too long or they will fail.
