[@yellouu_theree]

Always check docking connector in case of water damage. It oftentimes causes intermittent problems like you experienced with screen

[@migor777]

what is docking connector?

[@repairtech9320]

@@migor777 kzbin.info/www/bejne/aHOTaYCfZ8R7sKs it's a connector under the laptop to make it easy to connect the laptop like a PC... with external screen, keyboard, mouse, Ethernet etc. Everything connects in one shot.

[@GregM]

@@migor777 The connector that is exposed on the bottom of the laptop and which can connect into a dock to allow addiional ports on the laptop. You can see the docking connector when Sorin put the bottom of the laptop back on.

[@lis6502]

48:10 you did cleanup of liquid from main board, but i believe lid sensor might be on the daughterboard next to disk tray. Guess we'll see in next episode if ever this laptop comes back ;p

[@ATAG-yn5pd]

I would have checked the lid sensor immediately after I was faced with the missing backlight

[@wbrowning52ify]

Screen issue, there is a high possibility that there was some oxidation on the ribbon cable contacts. When you first opened the screen, you said that there was liquid damage on the screen board covering. Repeatedly connecting ribbon cable scraped off what was insulating the contacts. Just one possibility for consideration.

[@vanoverboard]

Yes i was thinking along the same lines ... only thing that would make sense.

Amazing work Sorin. I am learning a lot and admire your perseverance to get the laptop to work.👍

[@tomselestov6343]

I reeeeally loved this one, thank you Sorin! :)

[@kblectronix]

Masterful as usual but easily caught out. You think thing's are more complicated than they are. I do as well but disconnecting all the ribbons, ram etc is still a good starting point. I use HDMI test more these days as you can't hear a HDD rattle up. All the best.

[@alimoradkhan1]

Great job, Sir. thank you for sharing.

[@maklogetrich2378]

I believe the problem is the screen cable, might have something to do with the first and second pin (shorted?)

[@carlosgohn8659]

I have exactly this screen on acer laptop with exact same issue, and i checked led en pwm and got 3'3v and no backlight after disassembly ten times it worked perfectly

[@m3dcf]

Probably it's not a bad ideia to replace the screen cable, an internal line from this cable is probably ruptured and making intermitente contact. Screen is working now because you messed with the cable a bit, but probably the screen cable will fail again with the opening and closing of the desktop lid screen.

[@liveuk]

The laptop thought it was docked. Then you cleaned it. The cleaning fluid evaporated away and sweat conductive liquid was moved away by your re removal of the back. It then was no longer getting a "docked" signal.

[@Myth_62]

Great content as usual Sorin. Thank you. Can't recall ever seeing you use a ultra sonic cleaner. Are they worth it? do they have a use or is it something to avoid? other methods are best?

[@rajamudarungus7390]

Hi Sorin, I really love watching your content. I'm a huge fan of repairing electronics. Can i know what brand and model of DC Power Supply you're using?

[@TEMPODEAPRENDERJairoGSilva]

Hello! I'm from Brazil! Very good job. You are the guy!

[@servicetvlaptopcampina]

oh, when will the customers understand that you have to drink vodka, not juice or water, at the laptop... 😁

[@TheXlen]

Water is finish, beer and cola and sweet coffee are the main issue

[@servicetvlaptopcampina]

@@TheXlen that's what I'm saying, vodka is excellent 😀

[@rfr653]

Good job mate 👏

[@rickoneill4343]

I bet there was a bit of crud in that connector and when you disconnect and reconnect so many times it dislodged itself.

[@REVERSE_BIAS]

This is why I HATE liquid damage/corrosion jobs. When things start suddenly working again and you haven't pin-pointed an exact cause, the truth is that the fault could be caused by a multitude of possibilities...and worse still... could return at any moment!!! Had the exact same issue on a Fluke voltage tester recently. Worked perfectly...then didn't...opened it up, replaced corroded components, repaired traces etc...worked perfectly. Came to use it a week later... fault had returned. I sadly ended up scrapping it. Not cost effective to waste anymore time or risk safety by thinking I'd found the root cause. 😔

[@lis6502]

i've fixed sweet liquid damage with dishwasher and then displacing water with IPA in ultrasonic cleaner, but it was THT electronics ;d

[@vvtv2318]

good. respect.

[@47noeZ]

[@clivecottam1509]

What you should do is charge customers a small non refundable free whereby you enquiry about the system before they send it in, they can probably call or email before. Because these older systems its to feasible to diagnose and fix. If they insist sure. This entire system used is on ebay for just about a 100usd, another one is on auction starting at 9.99usd. Again as always perfect educational video.

[@Stabio_PL]

Perfect sunday :)

[@RichardNurcombe-u2d]

I think, Sorin, there may have been some sticky stuff on the screen connector preventing good contact.

[@QOTSAPT]

Lid sensor the entire time?

[@yellouu_theree]

Sound's very plausible. Also i had same case with similar tecra...same type of soda liquid damage and it took me some time to figure out that some of the damage was hiding in docking connector and it caused intermittent problems ..

[@maklogetrich2378]

maybe I've seen in the video early, when sorin open the lid, it's taking 0 amp, but when he close the lid, it's taking 20 miliamps

[@chumatez]

Nice one

[@mihaioleniuc1642]

Very Nice! 😎😎😎

[@alimahdavi9775]

Good Learn :) one day suddenly stop working backlight ! exactly how it fixed . at all original display is LG display and picture quality is NICE but one you connected is trash :)

[@Smaxx]

From what I've heard data pins right next to 18/19V power pins is totally what Apple seemingly loves to do, too, which gets extra nasty with liquid damage potentially bridging the two…

[@Dekmoore]

Love the longer vids, more chance for dodgy.

[@russelreda]

Sorin it's nice to learn 😅

[@SidneyCritic]

I guess it was a dirty pin, ie, plug it in and out a few times and it made contact.

[@cfq.tufanuf7601]

Could you not try an external screen?

[@lis6502]

30:41 if we don't have image on internal display AND no backlight while having fully functional laptop via HDMI, i'd go for Hall sensor of lid.

[@laboratorioassembler]

Maybe

I have a toshiba laptop that quits charging once the battery reaches 50%, any ideas what to check first, or just buy a new battery and try that. Everything else works perfectly, but note that it is windows Vista vintage satellite laptop and barely used for the past few years.

[@maklogetrich2378]

mostly battery issue

[@g4z-kb7ct]

Satellite battery will be 10+ years old, worn out. Replace with new battery or chinese copy new battery and problem should be fixed.

[@jaym5938]

Is the salt content in Pellegrino an issue? Shouldn't we use distilled water for sugary spills? And yes, stupid to put a data line next to such high voltage, but Apple does it ;)

[@xx3868]

I hate intermittent faults!! I'b be looking lid sensor or maybe iffy screen cable wires? Update Bios maybe? Bugs on this model? You moved that cable a dozen times and it still didnt work then now it works fine??. I would be wiggling everything to see if its loose and then lid sensor and then bios update.

[@lucianofz788]

it`s a mistery

[@lvlup2]

Personally I’d tell the customer that it’s fixed but if you want to be extra safe , replace the LCD cable.

[@MikeB_UK]

Surely you have learned by now Sorin that most customers don't want to tell you when they did something like spill liquid on a device. For some reason they would rather pretend "It just stopped working" or some other half truth. Why most people just can't admit to some mistake they make I can never understand.

[@tim0steele]

In cases of liquid damage removing the board to check the other side seems like a wise idea.

[@lucianofz788]

isnt tha what he didf?

[@g4z-kb7ct]

39:27 Well Apple does put hv and data pins together, that's one of the main issues with Apple laptops dying. But that's a good thing..... Apple laptops are good for landfill lol

Universal chargers usually come with a box of the most common types of connector. But if you don't have a specific one, you can get them from e.g. Targus (Google "Targus power tips" - I can't include a direct link or KZbin will remove it).

Hello Sorin and guys. I hope you are doing well. I want to ask you guys about what to do with my Acer laptop. It is stuck in boot loop. It shows Acer logo then shuts down within 5 seconds and keeps restarting infinitely. It also cannot access Automatic Repair, cannot access Recovery, cannot access Windows Install Media USB and does not detect any bootable media according to message in black screen when I place USB install media on top of boot order. The laptop only works and stays on while in BIOS menu. I have tried reseating RAM, swapping RAM locations, reseating Hard Drive, reseating CMOS battery... This issue started happening when I cleaned fan and replaced thermal paste. What can I do?

[@yellouu_theree]

Check your thermal paste spread . It sounds like bad contact with cooler and thermal shutdown..

[@AbdoCh-t8l]

@@yellouu_theree what should the spread be like? I checked it, it was just like the original was

[@yellouu_theree]

Well.. spread out evenly and thin.. 😄 verify that you have not knocked any nearby component or scratched a board trace somewhere for start especially look out for small resistor knocked out (used as thermal sensor)

[@markmorris6246]

Sounds to me like your Windows operating system is corrupted.Therefore can do a clean install you might have to configure the BIOS to boot from a USB drive with Windows on it. Another trick you can use to see if your problem is software related. is to create a bootable puppy Linux portable USB, boot from and if it works then you have better idea what your problem is.

[@maklogetrich2378]

try removing the hard drive and optical drive (if exist) let's see if you can enter bios or not
