Really nice video Steve. Love to see repairs bring the product back to life. Dehumidifiers are popular this time of year for drying clothes when it is too cold and wet to hang them out. Thanks!

12:02 - There are specialized cutters for IC legs cutting. From Weller. But they are 120 euros. They are built good and really sharp and precise.

[@TheChillieboo]

Man I love these repair videos and the way you walk through the process

[@brianwood5220]

Nice job, Steve. Love these repair videos and your logical way of going about them. Thanks for sharing with us.

[@luckywetland]

Excellent troubleshooting 👌🏼

[@andymouse]

Like the repairs and nice to see people using the wick carefully and correctly ! seen people vigorously rubbing across the grain and wipe a load of pads off.

[@sdgelectronics]

@@andymouse easy to accidentally do, especially with the bigger Metcal iron on cheap boards.

@@sdgelectronics :)

[@Mr.Leeroy]

was way too dry in my book though, wick loves flux and does the job at much lower temps when there is enough of it.

[@andymouse]

@@Mr.Leeroy It adores flux !

There was another Shinco which was a large DVD player OEM. They were the ones who made many of the better portable DVD players, and they even developed their own chipsets for them. There was one model, the 868, which was region-free and had an integrated Mega Drive. It would read ROM files off of a CD-R and run them on actual hardware.

Subscribed. Excellent tip on cheap boards delaminating with hot air. Thanks.

i like the hidden LED display on the side.

Nice repair👍🏻

[@stevec5000]

I'd like to see you repair some of those crappy Black & Decker portable A/C units that Amazon sells that all get returned! I had to try 3 of them to find one that would even turn on and it only lasted a couple of months and died and now it won't turn on again either! BTW, they have nothing to do with Black & Decker except the name, they are imported and sold by someone called W Co. in NYC!

[@electrodacus]

Yes the noise is likely from refrigerant lines as I have a fridge with same type of refrigerant and it makes similar noises.

[@pauldery7875]

Nice, Really nice repair. Paul, USA!!!

[@adamborkowski3175]

Well done!

[@DimasFajar-ns4vb]

your skills is amazing good job sir and zamzam water

[@GlennPierce]

May be fun to reverse engineer the wifi socket.

[@copernicofelinis]

Those beepers can generate nasty voltage spikes. Did you check to see if the rest of the circuit was protected by a freewheeling diode?

[@citizen69345]

Hi, nice video. Regarding the use of the Micsig vs. Picoscope in this repair, would the Picoscope be an option with the Micsig differential probes that you tested several years ago? Or does it have some limitations? Thank you.

[@sdgelectronics]

@@citizen69345 differential probe would have worked absolutely fine, just slightly more time to set up

[@y_x2]

Lucky to get the IC...

[@rlfvacslakenheath]

interesting video i have done quite a few chinese dehumidifirs with similar pcbs never seen this fault before usally its cracked solder joint loose connections or componets not soldered on. or the humididity sensor is faulty so e2 error.

[@anthonydenn4345]

Nice job. I noticed you used a 1k resistor in place of what looked like originally a 100 ohm. Was that for any particular reason, or it doesn't matter?

[@sdgelectronics]

@@anthonydenn4345 it's actually still a 100 ohm resistor, but a 1% tolerance version.

[@anthonydenn4345]

@@sdgelectronics Cool, I don't recall seeing that type before. Kind of confusing numbering system. Learn something new everyday 😉

[@ickipoo]

Wondering if something on the display board found itself between ground and the non-isolated supply...

[@sdgelectronics]

@@ickipoo or maybe some swarf in the metal box. I don't really see any witness signs of anything untoward though

[@101geo]

Any way of contacting Steve? I have a couple of Old dinosaur power amps made by Threshold in the 80's that need looking at.

[@sdgelectronics]

@@101geo probably don't really have enough time to take on too many repairs at the moment, but if that changes I'll let you know

[@catharperfect7036]

Isn't it rare to see resistors blow?

[@sdgelectronics]

@@catharperfect7036 they'll blow if their power dissipation is exceeded. I'm still not really sure what caused the issue

[@daShare]

@@sdgelectronics It would be interesting to measure the blown chip from the strobe line to the Vcc / Vss pins.

[@AdityaMehendale]

Pragmatic question: I have two options: 1) A similar dehumidifier (size, shape, power-consumption) 2) A kilo-bag of desiccant-pellets that can be regenerated with a microwave oven (placed outdoors, obviously) Which option is energetically more efficient to remove a certain quantity of moisture from my cellar? Thoughts?

[@sdgelectronics]

@@AdityaMehendale one of these will be more effective because it forces the air past the condenser. I would imagine this is more efficient too

[@MrMaxeemum]

Didn't "Technology Connections" cover this?

[@AdityaMehendale]

@@sdgelectronics I am in no time-hurry - so "effective" is less important than "(energetically) efficient". I shall (re)watch TC's video on the topic. My thinking was: as the silicagel collects moisture passively, the energy of the microwave can be concentrated upon just releasing the accumulated water back into the atmosphere. In a dehumidifier, the machine also heats up the room-air and has to push a lot of air around (which is in a sense 'wasted' energy). Thanks, both!

[@GregM]

Nice repair. That sure was a cheap PCB in it. Not a PCB Way one ;)

[@Appellation]

When I read "garbage on display" I thought for a second it meant very obvious, public-facing bad quality. In fairness I am tired. And an idiot.

[@Godunjoify]

Pacman 😂.

[@DeathbyKillerBong]

good repair
