Amazing Sorin thank you once more .I repair TV's for a living. To remove a tv screen held with double sided tape from the frame using a string works only for small panels and still not 100% safe , the best way is to use a piece of very thin , strong and flexible plastic like the ones they sell bottled water, or yoghurt's in. This is from hard leaned experience.
I stoppe fixing tv because i always break the panels
How do you use plastics if it's a string holding the screen sir?
@@ngwanindi The screen is not held by the string but by double sided tape, the string you pull cuts through the tape and the screen is released. Same happens when you use a very thin , strong and flexible piece of plastic to cut through the tape like a knife, I've done it many times with 0% cracking the screen no matter the size.
Ken Waweru thank you very much.
I successfully use pieces of the black plastic that can be found under the power sources by Samsung especially, or you can also use fragments of the polarizing film under the screen, the thin white ones
in that cases, you MUST plug an external monitor. this way you will be sure that the main board is ok, but something is wrong with the panel, or with the connector/wires that go to the panel
Sorin is too lazy for do that :)
@@gile849 because of experience he had! he said, that the laptop will do a picture with hdmi!!
but if u are not sure, then u have to use hdmi!
@@Knebebelmeyer Never be shure 100%, easy to try. If no picture over HDMI, then knows problem is GPU not screen...Im sombody who 40 year do electronics all kind :)
@@gile849 no u misunderstood..
if u have a picture over hdmi, then u can be sure, its the screen or the components that are filling the screen on eigther ways..data or power!
this is what i want to say
@@Knebebelmeyer Yes man this mus be a first step
Thanks Sorin.
See this many times with laptops that are used in al weather conditions. The connector cleaning is enough to get is working an sealing with rosin.
"I bet its working! ha, ha, ha! What did I told you! Ha, ha, ha" 🤣🤣🤣 Nice one Sorin!
you can reset the CMOS without opening the notebook ,by pressing Windows + V keys combination
Lucky customer!
Just because Sorin is there!
Hello Sir .Very Good day sir .

We Nigerians we love you so so much !!!!!!
Ive done a Sorin today, didnt have tools to open a samsung sandwich board and remove the short, so i just applied voltage until capacitor inside blowed up, just like sorin done with the iPhone x. Thanks
شكرا لك الله يجازيك كل خير على مجهودك لتعليم اصول وفن اصلاح الاجهزة الالكترونية
Nice one Sorin thank you. It would be great if you could make a video on how to open this kind of laptops. What tools are you using? How does the string thing work and how do you assemble it back together.
Hi Sorin. Nice video😊Maybe call the customer and suggest replacing HDD for SSD. It is more torture than anything to run w10 on HDD😅🤦🏻♂️
Great job👍👏
Sorin, this is the second time in recent you find this problem, I think that its a video card software switch stuck in HDMI mode, so the screen is turned off by default and by removing the screen and pluging it again you reset that feature. I suppose the customer use this laptop with monitor setup.
maybe you are right though he removed the screen connector from the motherboard side but still did not work.
Excellent Job and learning as usual.
One way to check if its loading propetly is to connect it to a monitor :) . Thank you for sharing
Wow, first time seen strings on the display!
great work Mr magic fingers does it again :)
I think customer tested with external display. Thanks for explaining strings..
Golden touch Sorin. Those pull tabs never come out smooth for me.
I had the lenovo legion, they added so much glue to the bottom bezel, much more than what you had in this video. And that is what broke my screen. Then, i bought a new screen and as i was putting it in, i shorted the board by forgetting the battery was in. My IQ is at least 200.
Thanks for showing this! What did you use to replace the adhesive strings, and what do you use to glue the bezel back on?
You can use the 8MM double sided tape from ifixit (Tesa 61395 Tape) It works just fine
Hey, do you need to put those "strings" back? What purpose do they serve?
Nice and easy fix!
edit: Ok, did some research, it's called "stretch release tape"
do not use rope string use contact cleaner spray just a little bit tiny amount it will crack the adhesive instantly and a little bit of pressure to help break the adhesive more easily but be careful of the screen getting some of it inside it from the sides
😍😍OMG I just had the same issue and that was the solution! Everything was working, CPU hot, leds, caps lock. Of course when you start with "no picture" you go for the video cable on the motherboard, but that didn't do it. Only after taking out everything I stumbled into this video and gave it a try. What are the odds!
Thanks, Sorin
Дядька ты красавчик!
It would have been nice to see how to reassemble everything. Not so obvious to some of us. :)
Thank you
Thank you.
Good job mate 👍
I had same. It's in bios. You got to switch the integrated graphics on
very nice job
thanks nice work
On dell notebook, press D and powerOn make a disolay test with color range ecc
Hi i have a same problem with sony svf152a29l but the thing is i connected the laptop to a tv with hdmi cable and there wasn't any data so what should i do?
Please sir can you do videos on MacBooks
I wonder if you have to replace those black ribbons used to detach the screen or if you can just seal it back in place with the frame.
Yes this is the question. Can the strings be reused? Or do we have to use hot glue?
you will have to use a double sided tape. I use it to replace frameless tv panels.
Hi, would u please tell me where can I find this chip ..2pts362d smd. This is a sony viao laptop ic. Highly appreciated if you let me know. Thank you!
Sir plz ,
I want you to do a teaching video on how to ;
1. set up a multimeter
2. How to set up a multimeter to be able to supply current to laptop board.
Plz plz plz plz Sir !!!
Would be interested in knowing how you put it back together. Do you use hot glue for screen ? What about glue for the frame?
Sir mine acer predetor suddenly stop working while working and try to on only keyboard light on then off and on again with blue keyboard light and no display
Well done my boss sorin , please am confused about the defence between backlight and picture.
In this case can i not see any light here but you are saying that the laptop has backlight.
Please help me on that 🙏🙏
Nice one
thanks 👍👍👍
Nice... one question, in Your experience, how often is the screen cable dabaged, i.e. broken wire inside the hinge. I would expect this as main reason.
very nice
Same problem here but fan is not running .
In my case the charging light turn on when i shut down the laptop , is that normal?
how about a laptop that working fine but not the bios it only gives a black screen with a slash on it
Good thing this model has HDD LED
Lenovo V14-IGL.
No backlight, no display.
HDD light ON, power button light ON, charging light ON.
RAM soldered (no extra slot).
No signal on external monitor via hdmi.
Battery disconnected and checked.
CMOS battery disconnected and checked.
no heat on CPU or RAM chips after being turned on for 20 mins.
This laptop has no fan, only a heatpipe and Flat metal heatsink.
Could the CPU be dead or should I reflow the RAM chips?
Fixed by magic touch again :D
It's a common fault , when i got something like this I always wanted to open the screen first if not the connector i will start checking voltages from there and move on
thank you for the video though i have a question
my laptop goes on, loads properly but after putting my password it brings a black screen with the back light on. What is the solution in case?
Hi . Where is your shop located? is it USA. i have a Gaming Laptop , I try everything but still not charging. I even replace the battery. I try all kinds of reset and updates etc...etc... Can you help please. I have a ASUS ROG Strix GL703ge . Believe me i think i try everything that i can possibly do. i beleive is some kind of short in the motherboard.
I have Dell inspiron 15 7559 i tried to flash the bios many time with different bins after cleaning ME but the laptop does not even light when connecting the power do you have any suggestions please ?
Nice!
with what do you stick the screen back on?
Helo am Alex from uganda
I would like to start a computer repair shop what can i do
Where are you from
The best
good jobs :)
Clearly you have magic electronic touch, its not the screen
No BIOS battery, explain please?
Some modern laptops have BIOS battery installed in main battery. If you dont have a standalone bios battery and want to reset bios, just unplug main battery.
wow its so fun live in european yes? . all part you buy arrive in 3 days and here its 1 month
why is your microscope video upside down ???
Australian microscope
