Whenever our Dyson does the cutting out trick I take it out to the shed and use a compressor to blow out the vortex chamber and the two filters.

Fair play mate. Repair don't replace.

Did you consider a lithium upgrade (probably either 3s or 4s would work well) and if so, why did you decide to stay with NiCd? (they won't explode, are very safe, unless you eat the cadmium)

Hi Mathew Lawrence & everyone please can someone help me I have a washing machine with faded or disappeared lettering, some letters are visible on the digital control panel, PCB i think it's called, please can someone help me so all the letters and numbers are visible again, it has ribbon connectors I think, will cleaning the connectors with alcohol etc fix my problem please, thankyou in advance. Great video thankyou.

I’m so glad I’ve just found your channel. I d always wanted to be able to repair boards like this

Hi I have 3 batteries like bebop 2 and they are swollen, 2 do not charge and one charges but when I put it in the drone it immediately discharges, are they still good for anything?

The wipers of the rotating selector switch will end up cutting the PCB copper tracks. Very poor design. Or is it a case of programmed fault?

If you've got a jeweler's loupe or something similar, that can give you a magnified view of the filaments at a long enough distance that you don't have to smash the glass, if you inspect each filament closely you should be able to find a little black dot on one of them, which is the failed LED. When it stops conducting properly it ends up with most or all of the full 300V across it, so you get very high power dissipation in a tiny area (and probably some arcing as well once the LED goes full open circuit). The result is enough heat to carbonise the yellow fluorescent plastic in the vicinity of the failed LED, producing a little black dot. Since each filament is a string of dozens of LEDs in series, and all 4 filaments are in series as well (or at least they are in the 2 LED filament bulbs I've had fail), it only needs one LED to fail and the entire thing is kaput. I don't see any way of fixing them either. Maybe if you could somehow get the filament assembly out without breaking the bulb, and replace the bad filament with a still good one cannibalised from another failed bulb.

These cells are damaged or have permanatly lost some capacity. Did you test them till full discharge?

Interesting! Thanks 👍

Hello please can you help out with this. I have an inverter with a different driver card. I couldn’t find the manual online. I tried to figure out wich jumper is responsible for the soft start and it was jp2 it work for few minutes and it still on soft start even after shorting the jp2 jumper. Please do you have any idea how to stop the soft start.

Get to the point, lad

Hello iv an astra 13 plate the fans on permanent Evan with no key in would you know how to test ths resister if it's in the stuck on position please .p

NiMH - how old is it?

Its actually not that bad. Ive definitely seen worse. The switching chip uses primary side regulation. The isolation distance is ok. The output diode looks like a synchronous rectifier chip. Probably ok for 1A, enough to run LED lights.

5:52 Ah, the schmoooooo!! Yes indeed!

What utter garbage. Absolute fkn garbage! They're not only stupid but blind as well. A 5 year old would know better than to DIRECTLY SHORT THE WIRES! Things like this is why I ALWAYS open chinese electronics _before_ powering up. You never know what you're going to find.

The problem with 3 lithium cells is that you need to use a lithium ballance charge board and it might not fit in the case. You can't just connect them in series. Easier to just replace the cells with NiMH but they'll cost about the same as a new drill.

You are one of those bloggers that insists on filming with one hand and trying to work wth the other.. this just simply annoys us viewers !!! investing on a camera stand won't hurt.

What's a good replacement battery to get for the Bebop 2 ? Thanks

Mate you need a tripod

thanks for your video. One suggestion would be to keep the camera fixed. I took several screenshots with slow playback, but it is very difficult to find out the value of R11 and C6. thanks.

Hello thanks for your video. Im brasilian and i need to r11 its 464?

looks like 2/3 sub-C. I'd push to rebuild with 3s or 4s Lithium NMC (does require taking away their old charger and providing suitable replacement).

Defective by design. I wonder if that was one of those post-manufacturing changes where they either were forced to change suppliers for the case, or someone decided to save a bit of money by changing the case.

Every inch is a Ground i think 😂 didn't they test before market

More China junk then, that looks so bad, I do wonder if they make junk just to annoy the western world, but we do need to stop buying stuff from China and go back to making our own goods for all countries.

Spark gap to wide

Is this filament LEDs are available in amazon India? Only the bulbs are available in their site.

You were testing some of the leds backwards, look at the printing on the circuit board. Short the burned led and the rest will probably work. It looks like they snake from left to right then left again as you move down rows 👍🏻

Buy a tripod !

Nice teardown. I was wondering if you worked out if all those LEDs were in series, or groups of LEDs in series, the groups being in parallel

The same problem has happened to me, I think someone from my family member might have accidentally used it on a heavy-wattage appliance which is not recommended, normally my smart wifi plug ratted 16amp as a result the relay stopped functioning however, the wifi section is still working. The relay model no is BPD-SS-105 DM which is not easily available in my Local Electronics Market so it becomes useless.

Saved my life there mate

Thankyou , got sold some trains ,all not working ,with your video, all fixed😊

Thanks for the information

It doesn't take 24v to fry one of these. I have one that died on a USB power bank. I was pulling the feed from it for over an hour and it died. At least one regulator seems to be fried (it's the only one getting hot, rather the inductor is getting hot).

I bet I wasn't the only one shouting at the screen that you have the male/female connectors the wrong way around... oops

Ha! A couple of weeks ago I did the exact same thing with reversed in&out on a power meter!

YOU SHOULDN'T HAVE TO REBUILD THEIR CAMERAS...WYZE PUTS OUT TOTAL GARBAGE.

Wyze cams are junk.

Hi did this solve the issue? Thanks for uploading this its exactly what I've been looking for.

Thank you for this video. I just picked up a second hand wyze car, plugged it into my camera, and it ran for about a minute before dying and getting super hot. A quick look at the board and that same chip is fried. And a quick google shows that wyze was replacing a bunch of peoples cameras under warranty, because the wyze branded battery packs were frying cameras. Which is annoying, but atleast I know which chip to get now :P

Great video. Is the trigger replaceable on this model?

Hi I am trying to remove the plugs from the sockets at the end of the board. The ones with spade connectors. I can't work out if there is a clip or whether they just pull out. I'm worried that I will break the pcb if I pull too hard. Please can you tell me how to unplug them. thanks

Wow that’s a next level break down. Amazing.

Thank for the video, I had the same issue on mine the capacitor was 0.1UF , since I replaced it it works fine , your video helped me , thnaks

Hello i have a jvc tv and the screen is blinking any idea what it could be? Thank you

what's the part number of the device? (on the chip)

Nice one Matt!! Where did you learn to use a hacksaw - your like a machine 😂
