From this we can learn that fuses are afraid of customers. They behave normally only in the presence of repair guy 😀
lol
This was my laptop. I bought it second hand and it was filthy and overheating so i had to clean it all up and decided to do new paste and pads at same time. I will also add pads where Sorin the legend suggested.
I also replaced a board which had a 3.5mm jack, 2 usb and an ethernet as it had been cracked by previous owner.
However it was fully working when i bought it apart from the usb and headphone jack when bought. Fully working after the pads being replaced just the backlight as we found out
never disconnect display when the device is on or the battery is plugged in. it always kills the backlight.
Hi may i ask how much did you pay for the repair ?
@@AmirA-oy2ef can't recall but including postage I think around £150-£180
@@psychosonny666 i meant just for the led backlight.is that the same?
customer's favorite words: "We have picture!"
good job!
It’s so nice to get a tutorial video from sorin every day.
"We have picture!" and Sorin smile: unique!!!
I know quite a few "Repair" people who would have replaced the screen without trying to fix anything. I wouldn't have done that, I'd have chased the fault to see if there was a backlight problem and tried to remedy the problem without resorting to buying a new screen right away. Sometimes it's unavoidable and you have to buy parts but not in every case!!
I like seeing the smile on your face after your diagnosis is confirmed! 😂
I saw that grin as well. Satisfying
Good Job and very quick fix !👍
@Electronics Repair School love the repair Sorin, we need some “And we have picture!” Shirts & cups dude!! ❤
proper calibrated fuse, proper repair!!
Fuses actually can die of old age, or a defect. They follow the bathtub curve too. Metal gets stressed and worn by high current, that's why your toaster and kettle elements wear out. Startup current is stressful for electronics, especially when cold. Sorin, you are awesome. Such a friendly guy. I learn a lot from you. I'm sort of between beginner and veteran, I still enjoy watching you work :) I can't believe they use tape to attach screens now instad of screws. Modern laptops are so disposable it hurts 🥲
Sorin what a brilliant fix well done really enjoyed it 😊
when i grow up i want to solder with ac plugged ❤
You are a truely Doctor
LEGEND REPAIRER ,even an experienced service technician don't have the balls to check and repair like this. In this kind of situation i bet service center people simply swap the display.
Sorin you've been my mentor for years now. Your just a badass!
You spoke when you should have been silent...
Good job, Mr. . We enjoy your video. Thank you. Thank you for all the valuable information - Saber from Morocco
Well done and Thanks for sharing ✅
Good job, Sorin.🎉
Great work Master Guru! Here's a suggestion you may want to consider. How about a video on tips showing how to improve the cooling of laptop computers? You know, where you can add a thermal pad or two, here and there, to hopefully lengthen their lifespans, and maybe help with their performance a little bit. Where should we place them like at this video's end. It could just be a quick tips or how to video, 5 or 10 mins long. I know I'd like to see one. Thanks again for all your videos. 🎯
really smart techniques of sorin
you are my hero❤ I didn't think that would work
True Master and an inspiration
Very good job! For initial diagnostic and to save time, the best way, probably, is to test first lcd / cable with any, even cheap, Chinese - lvds tester. With any torchlight, it is easy to see if the picture is present (when the backlight is off). 😉
Nice one Sorin!
Very elegant repair!
Hello ! In fact, even when the laptop was turned on for the first time, it was seen that there was a picture - a change in the lower part of the monitor, above the reflection from the lights on the keyboard... But it was visible because the camera was shooting at an angle...
That was amazing hello from Puerto Rico 👍👍👍 I’m new to your channel and looking to learn
Sorin is amazing.
Proper calibrated sorin
Good job doctor!
🤣😂😄😄.... Nice to have that proper calibrated fuse at hand....!!!! Great video.
😂😂😂😁😁😁
The best calibrated fuse ever!
Cheers
Nice job ❤
LCD-side fuses blow up when disconnecting the screen connector without removing the battery. The voltage spike from when they are plugged back burns them up.
The user had to take off the CPU cooler and the GPU cable runs over the CPU cooler. Their pulled out the signal cable without disabling the batter and caused the fuse to blow. Again Sorin refers to the board on the display as an inverter. Inverters were back in CCFL where the inverter converted the DC voltage into AC voltage for the old fashioned CCFL screens.
fantastic master
Perfect as usual.
it was a perfect job!
very nice repAir
❤👍👍
oh great job sorin.
Thank you Meister🙃
absolutely fantastic job, you're actually a wizard/surgeon
Nerd!😃... directly subscribed...
HI Sorin, may be sime time coincidence can happen... best for the customer and easy job form you but i leraned a new one and for these i can't don't thank you for sharing these experince... a next one thanks bye Francesco Timpano from Florence Italy
👍👍👍Good Job
you are amazing!
Master detective 👏
Hi Sorin!!
u r a skillfull one
goodjob
Partial good job. To find the fault it was a very good job but not replace the fuse is bad job.
I still ask myself, why didn't he replace the fuse?!
He used a proper calibrated fuse. He knows what he is doing.
@@rickoneill4343 This fuse helped the customer have his notebook repaired, preventing other things from being damaged. Now the next time the fuse is short-circuited, many things will certainly burn, making the repair much more difficult. This is the same thing as not putting a protection fuse in your home installations or simply replacing the fuse with a thick piece of iron. This idea of doing this is definitely a mistake. It is very easy to put a short circuit and finish the repair quickly and not think about why that fuse was placed there.
@@rickoneill4343 He didn't. He shorted the fuse with a wire!
@@fernandocastro-GPS Exactly.. He doesn't know why it happened the first time and this means it might just happen again..
You are good
thank you mr. sorin you are my teacher how can repay you ?
Proper calibrated wire 🤩
Legend.
I miss the unedited videos, maybe
You upload both from time to time
IPS screens are built differently. They are more darker than normal screen panels. Hence you cannot see the image that better without backlight missing.
8:17 nice little scratch
proper calibrated scratch
Hello🤝good job 👍👍👍👍👏👏👏👏👏👋👋👋👋👋
I think it is possible tto burn a fuse if to play with screen connector under powered circuits.
good job perfect.
LVDS connector on MoBo is to near of FAN and i think that customer actually moved this connector to be able to take off cooler.
16:01 - A fixed job yes, a proper calibrated wire, Dodgy Sorin.
Why you don't protect screen from scratches? You know, in contact with keyboard? When you open the screen for repair.
You've been getting some very nice laptops to repair recently! 😎😎
Only the best, guy has earned it
I had once on my Latitude E6430 where excessive torque on the screen while the back-light voltage is live blew the backlight fuse. Could be the customer testing the laptop with the screen bent at a specific angle and then the fuse did not like that
Haha we have "peeeekture"😅
Edit...
That start up sound, reminds me of Joe satriani's surfing with the alien, intro.( Original studio release)😅😅
ok I will say it.. good job!
Perrrfect
next time i will let the customer know to get new screen + job fee + keeping the old screen 😅 lol
Brilliant but why not replace with new encapsulated fuse
Excuse me I need to check where is the short in my laptop is it the gpu or mosfet or something else and I just have multimeter, and if the problem is in the Nvidia gpu how do I remove mosfet without hot Air station. Regrets
I have an Asus TUF with exact same issue powers on etc. Replaced with new screen and new lcd cable - no picture on screen. There is picture only on external screen. I can't figure it out. Ideas? Thank you!
There's fuses near JEDP1, the display connector on the motherboard. I had a Nitro 5 with one blown right up in pieces. It's a 19v high current circuit.
I know it was the fuse but is it just me or do those pins look way off to towards the right 1:38
I have this same model, when i power on, screen remain blank., no start up sound.
Only keypads lights are on.
it is reusable pull tabs.. you can use it again just dont let it stick to itself
sir please answer laptop motherbord outside volt 11.1 and 14.4 battery ?
"Proper calibrated fuse".... now, how many amps that strand carry before blow?
The customer was cleaning a display or inside with power left on
How safe is it to just solder a wire to bridge those two points, isn’t it bypassing a fuse or capacitor?
fuses don't blow by themselves. That's what books say.
With not proper calibrated wire we could burn to crisp this board.
I wouldn't watch if there wasn't a "properly nice laptop" to repair 😊
Sorin, the style, suspense, and resolution of your work is a real art… It is absolutely amazing that your content is unscripted… and in my opinion - the very best of TH-cam 🫶
I Love that kind of fault!!
wow 😮
Customer probably removed the screen connector without disconnecting the batter, that caused a short and the fuses acted as intended, protecting the circuit.
Hard to believe. The short circuit should have been after the fuse, not before it.
A short at the conector or in the screen cable would blow one of the resistors near the connector, not all the way up the inverter. I've had it happen on a Nitro 5 recently.
What would Sorin do without the calibrated fuse wire !
Another mystery fuse failing for no obvious reason.
Fuses actually can die of old age, or a defect. They follow the bathtub curve too. Metal gets stressed and worn by high current, that's why your toaster and kettle elements wear out. Startup current is stressful for electronics, especially when cold.
@@supergeekjay I agree but going by the spec this laptop can only be a few years old.
The more likely reason is an underated fuse or the wrong type of fuse.
Antisurge fues were used in TV's etc to handle that initial start up surge also low value
resistors were also used in series for the same reason.
In this case i suspect that the type/rating of the fuse was not correct, Sorin's calibrated
piece of wire would have been a better choice !
Would an external monitor be a good idea to find out the laptop monitor is broken
.... you should do streaming on youtube
you could 'v pluged a HDMI cable to a monitor and test if there is picture displqy or not
Public service message not to touch the screen connector with the battery or the charger connected.
Hello, can backlight fuse be replaced or the best way is bypass?
He didn't bypass it. NEVER BYPASS A FUSE!!! He added a very very thin wire which acts exactly like a fuse.....
@@g4z-kb7ct that wire, you are right still a fuse, but can carry ton more amps than the stock fuse :D
@@user-kr8tp3ko8z "CAN CARRY".... maybe. Do you have evidence to suggest it does? Otherwise your comment is pretty pointless and a waste of time typing it. You are suggesting Sorin is an idiot and doesn't know anything about current.... try to think before you comment in future.
I think he preferred to replace the fuse with a properly calibrated wire because of the risk of heating the area too much. Do not forget that it works on the screen. On the other hand, he could use "my little friend" to remove the fuse...
@@panaitepaul6798 A small part like a fuse or resistor or capacitor can easily be removed with just a soldering iron by adding solder then heating both sides. It's a common technique well documented. When in very delicate areas even larger parts like TSOP48 flash ROMs can also be removed with just a soldering iron using another technique that I use, which I developed :)
You seem to work on a lot of Acer computers, just thinking.
❤❤❤
Electronic repair school uses more multimeter than Tronixfix, who uses the most the toothbrush
Proper calibrated fuse 😂😂
I wonder why you don't put a fuse instead of wire yeah i know it will workin in that way but i will add a proper fuse.
since you hot wired the fuse to bypass it i'll bet you find out what shorted when the inverter goes up in smoke from not being fused anymore........
a propre calibrated fuse 😃
