You are the only KZreadr that when publishes a video I have to watch immediately. And you grab all my attention. Thank you.

Ive done some amp repairs. Usually its after market amps. People hook them up wrong or do not tune them right and end up blowing them. Then I would fix them and tell them to check their wiring and settings. Then they blow it again and accuse me of not fixing it right. So, I really scaled back on repairing them. There are a lot of people out there that think you can just hook them up and go. Thank heaven this is a factory amp.

Thank you for your insight on audio amps, you're years of experience is priceless for us techs.

sorin we all love you i'm from Ethiopia i see allmost all your video i learn a lot you change my life thank you

Thank You for always sharing your expertise Sir Sorin!

Sir.... before I even finish watching the video... thank you. From Trinidad and Tobago.

I have not seen a video from you yet that I have not watched all the way to the end. Love it! Keep em coming!

Thanks sorin, some new appliance for us to learn. Thanks you legend.

TDA1565TH is the chip you need good luck finding it! also this amp is a class AB. I would swop the chip with the one next to it just to see because the fault could be with pin 2 mode/standby/operating mode circuit.

Thanks Sorin , another great video .

These BMW cars have Bose speakers on them, so this amplifier may well be a Bose high spec amplifier too. Great videos, Sorin!

Hi. Shorted or burnt speaker will short that chip.replacing it will stop the battery drain.but before installing check the impedance on that speaker otherwise it will short that ic out again.nice video and diagnostic

Great video, waiting for the update, i hope the customer wants it fixed xD

Hello Sorin Yes watching you everyday from indian Ocean

15:00 (expecting) let's modify it and use another common chip amplifier! 🤣🤣🤣

Nice repair video

Thank you oh engineer

16:30 TDA1565 supply voltage is ~14v. it powers directly from the battery, thats why it drains current even with main power inverter turned off .

New to electronic work/repair and have been learning a lot from your channel so thank you for that. What temps do you hot air? I saw your video on your old tool for manual hot air which was great and I know everything you said in that video about the hotter the faster the better but I seem to have a hard time. I hot air @ 390c full ait power and it still seems that the parts take a long time to come off. Not like yours as they seem to pop right off. Any suggestions or help would be greatly appreciated. Thanks again and keep up the amazing work.

Great tuition. Are you a qualified technician

Those chips are likely in standby, but the damaged one is shorted to the rails. Bad speaker maybe. I would not experement with that amplifier, it could become an expensive mistake :-(

Yes check the cars speakers, then look for a used amplifier from a scrap dealer and rob the chip. Or like Sorin suggested talk to the customer about not having that speaker in circuit.

Check the cabeling also! Often the cable is shorted to Car ground. This will destroy the amplifier!

20:30 "Otherwise I can do some crazy things..." when the dodgyness switches on. :D Clearly at this time you cannot solve it without a donor or some dodgyness. :)

cool. problem caught right away. all it took was a brunt finger : )

Better replace the chip if you find one. Otherwise leave it like this. But customer have to check his speakers and wires anyway.

The amplifier has a separate power supply. The amplifier is switched on by the RAD_ON signal from the radio (> 8 V = ON / < 6 V = OFF).

Looks like pin2 controls the mode of the chip, perhaps pin 2 is shorted?

exactly what i was thinking, where do you start, what direction.

this is an interesting one please DO update us, especially if you are planning any dodgy stuff with the board if you put the channels of 2 speakers in series one with the other, would the amp be able to drive both?

17:57 conformal coating.

Sweet

I think all automotive PCBs are coated, at least all the Mazda ones I have taken apart were coated

Most IC's in automotive stuff is masked so searching for information on them is rather difficult. BMW especially has a lot of custom made stuff you cant really get anywhere. If its not masked is almost always obsolete. Aliexpress sometimes if you get lucky but if its not a commonly failing chip like injector drivers then even if you find one its probably something else and just labeled with what you want.

The timing couldn't have been better. "the current is just little bit, so how we can know.........." what is HOT!!!!

I have a high suspicion the installed speaker was flooded with liquid, as water damage that led to a condition as constant to ground.... short. I would be very curious as to operation via reinstall in end use. Was that as to an automobile? I hold the view, install of a new chip would be shown to new, unprotected ground and subsequent 2nd chip fail. I think a clear, repair as to device would be to cite, the potential for high heat, as to a consuming fire. Replacement of chip demanding discard of speaker . *replacement.(also)/ What an interesting repair problem. Please mention how the job was finished to customer need. M.

Is there a short between the sense pin and 12V

Round of applause matey ! Bl**dy car electronics. Cheap and nasty construction and bad circuit design but high replacement prices ! I got a failed motorised temperature flap on a Skoda Fabia ventilation system . . drains the battery in two weeks. To change the ventilation flap motor, which itself costs £70 !, will involve removing a fair bit of the dashboard and cost £500 ! My solution, take out the fuse and, also, oddly, the diagnostic socket fuse . . . battery drain gone !

Sir, one question, and i cant help not to ask you this one. What was your College course? You seem to know everything about electronics. I hope you can answer back, as Im planning to follow your footsteps. Thanks.

When one is blowup then the output is being wrong. One speaker making a short ? Like you show a little burnt connector pin.?

please more explination about serial mode and the ohms output ? in paper with diagramme if you can please thank you

Disconnect or bypassed that factory amp, suggest the owner to upgrade to aftermarket 5 channel type of amp and the rest of the front and rear 2 ohms speakers to 4 ohms..

@Tegelane5

Aftermarket 4 ohm bridgable amplifiers can handle 2 ohms easily. Problem would be other circuitry inside BMW amp, original headunit might not turn on without it. But tda1565 inputs could be connected to outside amplifiers inputs. Building it, so it looks decent is not worth it probably..

Hey Sorin try sonic electronics

One of the speaker may be shorted. Therefore. The audio ic is defective.
