Can I use same DC to DC convertor without removing any components

Hi, could you explain to me, why at 2:33. you plug in both endings of the cable on one side of the tester? I think you should plug in one side of the cable in one side of the tester and the other side of the cable into the other side of the tester? Best regards and sry for my English ..

Someone gave me one for free at a carboot. Once I realised it was redundant, I was gonna have a peerk inside but you saved me the bother - thanks.

I have the same issue, and i dont have the tools to replace the mosfet, can i convert it to a passive subwoofer? Or can i buy the module online? Thanks for the help

Sir...i have makie srm450v2 active speaker..when i turning on speaker both led light staying on..(thermal led light and peak led light) how to solve this problem...

Thanks for the tip with the Mechanic DT3. I will probably buy it too :)

Hello friend, are you still using the Xsoldering Pro station? Gradually, my C210 soldering iron started to log off and yesterday it stopped working completely. Doesn't work with any tip :(

Do you think using a USB D lead would work?

So happy to find this video. I finally replaced the last Sonos speaker that required this old bridge, so I thought it would be fun to teardown. I'm a complete novice, so this video was really useful to help me identify and understand all the components. Interesting, but not surprising, but my model's flash storage is from Macronix. The comments on the antennae was also appreciated. I could see that one was connected with traces, but I had no clue what they were meant for. Thanks again!

You re-assembled, tested it and it blew again because you did not fully fix it? That is what usually happens after replacing that FET and nothing else.

Looks great! What is "TURBIM15"?

Great video. can you help me? Where did you get the pot switch? part number

😊

Going to try this on my monitor's PSU... it has the very same problem.

Quindi praticamente che pezzo bisogna acquistare e di quali strumenti servirsi? Sono ignorante in materia, cosa devo cercare su google per eseguire la riparazione? Grazie

Great video had same problem with my sub 🙏🏼🙏🏼

Any chance you can link the replacement parts used please got the exact same problem need the mosfects and the controller chip

Brilliant video

❤❤❤🤫🤫😼😼🐤🐤🐣🐥

Powered speakers... or old school amp rack...? Old school amp rack wins every time.

I have a similar PSU and it keeps blowing fuses in the plug and it also blew the little on-board fuse next to the AC input connector. That little round thing next to the fuse appears to be a dead short circuit. Is it a capacitor or something else? Anyone know?

You could have drilled holes in case because there is mounting in holes the pcb anyway

Hello! Do you have a "chinese" firmware for LPC2387 MCU?

看起来很不错的焊台，正想入手！但是，我看到有人说，容易烧坏烙铁头子，请问是这样的？

这个焊台使用怎么样？听说送烧坏头子，请问下是不是真的？我正考虑入手呢，可以解答下吗

这款焊台，使用起来怎么样？我最近想入手它

Evening Sir , don’t suppose you other a repair service for this unit ? My daughter has one that doesn’t power up . Supply in is good and internal fuse ok . That’s about my limit lol .

thanks for the video - some knowledge with boards and components, so I will attempt to repair mine.

Hi, Thnks for the video, mine doesn't turn on after flashing an ecu with ecuflash, it was fine for about a year, it doesn't turn on with usb but has voltage on board (4.8v). I tried an other one with ecu flash and it flashed the ecu once and now it's same as mine. Do you have any idea?

Who ever fixed it first time around didn't do a good job

Do you offer repairs?

I have the wharfedale dx-2 package, the subwoofer, stopped working, no power on LED, the board is WH-S10E (power), cables, switch and fuse ok to main board, I moved the untit the other day and LED came back on but nothing again now, checked FETs no shorts, and switching chip hasn't blown, no obvious signs of any chips or caps blown, no discolouration either.....could be a dry joint but can't see evicence of what would be a stereotypical dry joint, looking at the output it seems to suggest MUTE, 127v, G and +27V, is this correct, can put it back in situ and test, if you have any pointers, would appreciate the help.

i have usb tester fnb58 device which is showing vbus 0.7 volts lower than real. Tried connecting another test device in series and it still shows the actual number of volts. can you show me the volt alarm mechanism on this usb device

Where did you guys get the little dodar from? Please.

I'm impressed your work and this video. My laptop fell with the dongle in it. Dongle side hit the ground. After that I had to put downward pressure on the dongle to make it work. I felt I lacked the practice and the equipment to do what you've done. But since mine wasn't severely damaged, I saw another video where you can remove the electronics and bake it in an oven. I tried 400 F for 8 minutes. The performance seems fine now. @the equalizer I'd be curious about your thoughts on this method. Thanks again for a great video.

How is it holding?

This Power Supply is always on, it always outputs 12V and it should always be able to deliver 25Amps. The Power-Button just controls the Mainboard through the smaller connector going to the mainboard. The reason, you see the voltage drop at 2-3A load is you less than ideal connection. I am surprised that you own an electronic load and did not realize that.

For those asking about buying pots to replace- search your pedal schematic from boss. It will tell you the model and part number. Mouser electronics had the one I needed

Hola tengo una Jabe UD 1200 despues de un tiempo trabajando se me quedo sin calentar la apague encendi y ya solo me queda en el logo sabes algo de esta falla

It worked for me. But I used a regular soldering iron and that was such a pain. I do recommend using whatever is used in the video, it's way more effective. Thank you sir.

Hey such a great video, by any chance do you know where to get the reverse usb plug with the three pins?

It was a great video and explanation! Than you!

hi if i connect the loose earth to the lamp housing metal does that make it safe?, is there any thing i can put over where the wire solder joints are ?, like nailvarnish or something?
