We're all waiting with baited breath for the final "Yes".. Very addictive repairs you do..

Excellent repair! Recently discovered your channel and I've binged pretty much all of your videos. Subbed and looking forward to the next one!

Great job. For fixing vias you should just drill hole and solder both sides with wire inside. Drills down to 0.1mm are easy available.

You can press the yellow button on your Fluke to wake it up from slumber, you dont need to turn it off and back on again. ;-) Love your videos by the way.

All I can say! Is you are an absolute wizard, loving the videos, also the variety of things you repair

If you're looking for something to clear very small via's, buy a selection of acupuncture needles, cheap, strong and work a treat, keep up the good work. (Electronics engineer in Teesside)

Great Fix, I guess the charger had been stored in a damp basement ot got wet outside when charging a battery still inside a car

Another great fix, very informative Thx, keep 'em coming Mick

Wow! Never seen something that bad, that seems like someone either 1. Dunked it in water or 2. Was left out in the rain. Nice that you managed to fix it in that worse shape!

Love your videos. Greetings from Brazil.

Cool! I have bought such a grinding pen as well, and found out that it fits great in the plastic casing of an epi-pen.

If you want something to clean the corrosion and solder mask off tracks, try a coarse fiberglass pen. Just be aware of the dust it generates and don't inhale it. I vacuum it away. It works really well at just not damaging the copper trace itself. You can get different refills for these pens. Fiberglass, brass, etc. I think I got mine from RS or Farnell (E14) years ago.

Nice fix.

Another lovely fix though Mick, well done once again 🙂

worth knowing the “start/stop” is for an agm battery like the one you had, as opposed to normal wet battery. They are very good chargers but I had a couple die, blowing the internal fuse which I couldn’t troubleshoot past the simple things like caps - I binned them unfortunately.

Great repair as usual. Thanks Mick 😀

I wouldn’t mind betting that the unit was left out in the rain.

Good work! Also great camera work. Video is clear and easy to follow on what's happening.

Great video - thanks for sharing. A suggestion for via repairs is to just drill out the hole (you can do it by hand with a small drill bit). You can then pass your repair wire directly through the hole and just solder it on both sides. Makes for a quick and easy job.

Excellent work, as always. For a second there I thought that fan, at the end, was going to just keep speeding up, sounded like a jet engine...🤣🤣

You are inspirational I wouldn’t normally try to repair something as badly corroded as this

Little ranting follows... Have had couple of lead-acid battery smart chargers, including one of Ring brand (which died with a nice bang, not going to repair that junk). After having headaches using them and getting to know their quirks and pickiness, I've mostly back to using oldschool "dumb" chargers. Only few components, therefore not much that could go wrong with them. One of the last smart chargers I recently tested out - the thing forgets its settings every time it loses mains power even thou it is still connected to the battery. When mains power is back on, it won't resume charging but waits for settings again. It's charging cycle is also questionable because it seems to stop when charging current drops below 500mA, not even trickle/small current pulses after that. Only after battery voltage drops below 12V will it activate again. So much for a "smart thing" that is supposed (going by description and spec) to keep battery charged/topped up for all the time. And yes, it does have warm/cold temp, charge current, 12/6V voltage selectors on it. All those have to be set too.

keep them comin pal ove watching u fix them as a engginer myself i love it,

Excellent fix Mick, looked a mess at first but all fixed thanks 😊

Like your videos. We actually use the same model of the Fluke 179 multimeter. When it goes off you can just hit the "light" button to start it again. Just wanted you to know that. :) Thanks for all the repairs! Keep it up! Kind regards from a fellow electornics repairer from Sweden.

A perfect wire to use when you have both traces broken, and vias messed up, is insulated wire wrap wire. It is thin and flexible enough to make trace runs, and usually can fit through vias and easily soldered on both sides making solid connections... I've done more than my share of such repairs...

You said you didn't have anything to unclog the vias but given the board seems to be only two layers, it didn't sound unrealistic to *drill* them with a 1.5 or 2.0 mm drill bit and put a bit of wire inside soldered on each side

those buttons are CRISP even dirty, love those clicks

I agree with @daShare, use a fiberglass pen to remove the coating on the trace, it dont destroy the copper trace, and it cleans it better than the tool you use.

The auto subtitles said you were trying to 'pork' something through the holes 😂😂

I always watch My mate Vince Channel and your channel pop up on my recommendation and you have a new subscriber👍

Surely a good repair, but i would have dissasembled the screen also to check for moisture damage.

Good luck sir 🎉

Gotta love it when people say "just stopped working" when it's obvious it's has liquid ingress.

great vid as usual. Just for information, keep an eye on your incoming voltage as you shouldn't be getting any more than than 253V max (10% on 230V is the absolute permitted limit). You may need to contact your Dno & let them know. Over voltage will shorten the life span of your appliances.

Great repair, but you mucked up screwing in the main board. You had one screw left on the blue mat.

I use micro drill bits to get through the vias.

I am surprised that you put the whole thing together before testing it. I don't have enough confidence in myself to do that, because the chances are too high that I'll have to take it to pieces again! So: Either you have supreme confidence in your ability to fix things the first time (which you justifiably should have); or: you've tested it off camera already and you know it is going to work 🙂 Either way - well done! Clearly a liquid spill through the front of the charger with something corrosive - ? battery acid (unlikely) or Coca Cola, or what?

Excellent work as usual

love ,love love love your channel..ihave learned so much....can you link me to the flux you are using. Have an awesome day.

If I may suggest, sometimes, better than an IPA is to use zippo petrol for cleaning boards, especially with conformal coating on the surface of the board.

Thanks for the video mate, I bought the exact same charger brand new from Halfords and it's set up & charging (well the % has just moved from 70 to 80 so I would assume so), however as the numbers are alternating between V and A on the screen, I'm getting a reading of 0.00 for the A, surely this isn't normal (?)

You could use a set of welding tip cleaners to poke thru the vias if the hole is large enough.

Could not believe you didn't connect up the TX and RX lines to see what was going on there. I expect it is serial protocol, normal serial port. I would give anything to see what it has there

As Alex from Northridge fix would say " And look at this ,we have Hiroshima " Nice work again John,who doesn't go nuts like Vince when he discovers that his repair actually worked. You are much more sedate John,so when i am listening through bluetooth headphones i don't have a heart attack when you are victorious.😂

I have the same charger & it keeps clicking on & off & does not charge, have you any idea what it could be, sounds like a relay. Love your fixit videos 😊

Well done. You may want to build a dim bulb tester (or modern equivalent), much as an almighty bang would be entertaining for some viewers, it may shorten your battery life.

“Someone let the cake out in the rain .. it took too long to ‘bake” it” 😮

Nice work ! Didn't look sticky or anything do you think it's just water that got in ?....cheers.

Nice 👍😊

The main IC seems to be Haier ASIC or pre-programmed (OTP) processor, probably based on 6502. It's odd that they chose that processor, since that seems to be really obscure.

Not so smart chargers, bought one, never another. Its ok for it to offer an opinion, but not to decide whether it's going to output or not

What grinding pen are you usinf

nice! :D you whirled that control board so much, i lost the position, so, i was sure you "welded", as a chinese will say, wrongly that MCU... and i was expecting some nice pyrotechnical effects! :P but it wasn't wrong, so.. good job! :D that MCU i think is a Holtek... so much domestic appliances use a MCU from them, so... educated guess...

For clearing those via's, have you tried pulling a bristle from your workshop wire brush and using that?

You have mentioned your voltage being rather high lately. The actual voltage in the UK is 230 volts and the frequency is 50 Hz. Note, however, that British energy regulator Ofgem permits a tolerance of -6% to +10%, which gives an allowable voltage range of 216 V to 253 V in the UK within official limits. But, in MHO that upper limit must be putting quite a strain on electronic equipment designed to be supplied with 230Volts.

I would reopen the unit en coat the controller pcb with lacquer, just to protect it more.

Hi , I have the same battery charger and mine is only working on battery test mode I am unable to use it on charge mode ? Would I be able to send it to you to check the charger for me?

Possible reenactment: *charges car outside garage Client: *accidentally slept and then it rained OR he lives near a beach those salty vapors can screw everything up

Hi, what Kind of microscope do you use? Link?

is it possible to stick a wire thru these vias and connect both sides that way?

Heck yeah , you got a great lil charger for less than 20 bux........

Can I learn the knowledge of electronic from u❤😊

May i suggest a fibreglass pencil for removing solder mask.

You need an ultrasonic cleaner to put these things in. Worth the investment.

how much would you charge to fix mine? i hate the thought of wasting the money on it. I dont have a proper solder heat gun or a micrscope with good enough zoom to make this sort of fix unfortunately.

Please use some kind of fume extraction 🙏✌️

Hi I have a small Pcb caravan door latch closing board that is no longer available I have tried 4 3 days to fix it I would pay for you to fix if possible Desperate for help Nick

It was working fine until I charged batteries under water. 😊

Haier microcontroller

Faulty. Ring. Smart. Battery. Charger can. l. Fix. It

254 Volts ? guess UK doesn't have to go down to 240 V max anymore since they left the EU ?

Why did you use such long wires

I have this and it says 12.4 on Auto charge but 0.0a . Says its charging but no noise or anything and stays on 60 % . Help 😮

What Is I.P?

Nice repair :) I was wondering if vinegar with salt would get rid of the corrosion on the vias, as I saw Edd China cleaning oxidized copper wires using that solution: kzfaq.info/get/bejne/frVobJCDktK3fn0.html Perhaps then flush it off with ipa. Of course if the copper is completely corroded away, you'd still have to use jumper wires.
