Thank you for sharing your experience Sorin. I love watching how you do your thing, and it has really been of tremendous help to me. I doff my hat for you Sir Sorin.

Glad your back! I hope all is well with you. Thanks for your videos and your insight.

Thank you Sorin for educating so many people through your video's. I learn many things about how I can understand some of the common fault that occurred from a laptop. You r the best.

Another great video Sorin! Thank you so much for sharing your incredible knowledge! As an electronics technician your info is priceless!

Computers equipped with ATI chips always end in the same way... taking a hot air bath for it to work a couple more months until it finishes its miserable life...

It’s always a joy to watch your videos Sorin 👍🏼

Thank You for always sharing your techniques teacher Sorin :)

Excelente vídeo

I had a laptop with the exact same problem. It DID turn out to be the screen. Since it was mine, I just permanently removed the screen and used it as a "desktop" with a plug in VGA monitor. Actually...I still have it somewhere around my home.....🤔😀

You're the best computer repairman in the world! I have an HP doing the same thing, except I get a picture on the HDMI port. I hope it's the screen because I ordered a new one. This HP laptop has the glued-on bezel and elastic tape strips holding the screen in. Makes it tedious to get the screen out.

You made me love electronic again, well f... tiny chips with 300 pins on phone boards makes me hate it again lol but you are inspiring and i admire your work a lot. Even if its a dodgy way smiles well i bet you would like to have time to fix them with proper way..Thanks..

what's your thoughts on reballing and why never done it

Teacher Sorin is back with new magic. Sincerely, from Slovenia.

Sorin may God bless u 4 me I pray 2 hv knowledge like oh God

I really like this guy.

your a good teacher from tony

You are a true living legend.....

Another nice video

Well done

Nice work but you can extend the life of this chip by adding a part of copper over it to help to dissipate the heat more quickly and effectively

nice video, but i think it would be better if you used a copper shim (and thermal paste) something between 0.3mm or 0.5mm, because the blue thermal pads that you use are not the same as the original pads they used, the blue ones are mainly used for vram chips or coils or mosfet nearby, maybe in rare cases on atom cpus, that have low heat generation, the original pads they used on those gpus were gray, they had better heat conductivity and crumbled when you pressed them, and as far as i know are not sold anywhere.

Need more videos,,, my mentor ❤👌

I had an HP laptop with backlight, but no picture and it ended up being a bad contact in the display connector. I cleaned both ends of the connection with IPA and a brush and the problem was solved. The laptop had some liquid damage in that area.

i dug into the specs on this due in part by the AMD Vision logo. A Phenom II dual core at likely 2.1 GHz. I am curious as to what the charges for your work were.

Nice one

You are my long lost Father Sorin. 😁

Teacher, this is a temporary fix !

I wonder why the customers never clean their laptops, when giving them to your shop.

Over the next couple of days my mission is to fix an Acer nitro 2021 spec 1 week out of warranty.. Ryzen 5 3060 16gb ram. Completely dead. No lights. Nothing, tried battery reset and physically disconnecting the battery. I will strip it down and start to check other components. Hopefully your videos may lead me to the answer

amazing

Recently, I was given an old ACER Aspire 3100 laptop with no screen at all (external port didn't work either) to fix. My first idea was to run over the gpu with a hot air gun, like in this video, but I didn't have the hot air gun. I found a donor for cheap. I am sure that this was too the issue!

Sorin the great laptop technician Thanks for all the great knowledge. my Dell Rugged 14 doesn't display when we power it ON it shows light on the keyboard, then if we power it off and On again for the 2nd times it takes like a minute or 2 to display then works well after that. how can that fault be fix? please help needed

Watching master

Hi like you I'm in Zambia but I recommend you my expats

Great video! I like your work! I have an Acer with backlight but no picture. Sometimes it shows picture let say 1 of 10 power off/on. On display connector I am mesuring 19.4V when no picture so the display cabel is OK,the screen is OK beucase it shows the picture, can it be the graphic card like in this video? Sorry for my bad english its a second language for me.

Faulty edge core of graphics. For replacing the graphics card chip.

Sorin that would have a dry joints under the graphics chip. Reheating the chip to reflow the solder underneath the chip.

sir nice video.. what the brand of your electric screwdriver?

Clean the fan and add new thermal paste after this repair and the laptop will last much longer / also if possible place an o ring on the chip and fill with thermal paste then put heat sink on the more heat that can be removed from that chip the longer the laptop will last.

I have a similar laptop, a 9 year old Sony Vaio SVE series. This laptop easily holds 4K video at 60fps, but 4 months ago I ran into a graphics issue i.e. red lines and a lot of glitches. I solved it the same way: reflow. Now I control the GPU temp more strictly. I'm using Linux, so I wrote a shell script that forces the fan to cool everything down if the GPU hits 55 degrees Celsius. With the forced fan the temp drops to 45-48 degrees. I think I can get lower if I will put some Arctic MX-5. Everything works good. And yes, the problem appeared because some months ago I tried to play heavy games, so it was the "last straw" for my Sony Vaio. I think this kind of problem is a design problem. You put good chips and only one fan... A hopeless situation, every kind of chip will melt.

Thank you for your video! I have a similar problem with my Asus laptop. Only the backlight is working (and I can adjust it, lower-higher) but no picture is displayed. However, if I connect an external display, everything works normally. Is the problem in the GPU? or I need to replace the display?

Pls kindly advise how to repair dead motherboard 7 display problem on Acer eMachine D728 model Laptop,Sir.

The newest version of windows 10 allows you to turn on the windows startup sound in the sound settings

hello which battery screwdriver do you use very nice thing would like to order it greetings from the netherlands

I have sony like this but voltage disappointing until first mosfet .any idea where to look first.no short if I short mosfet with tweezers.or inject after mosfet voltage.thanks to any who could help

Isn't it ironic, it takes heat to solve a problem caused by heat.

Hello from Greece! Brand of the electric screw driver? its lovely

I have similar problem. I solved it by changing my hard drive..

Do we see same symptoms when ram has fault or faulty bios (black screen with backlight) ?

in case of frozen BIOS dont open the laptop u can gain time by removing the baterry and hold press the turn on button btwin 15 and 30 sec

You're always best ❤️ thank u please talk about new iphone s

Where are you located? I'm in the UK. Do you take repairs by mail?

I have an HP DV9700 with backlight but no picture. I did a reflow of Graphics card and still no picture. Any advice on how to fix this problem? Also, where can i get one of the slimmer heat gun you used in fixing the Acer 5535 that turns on but no picture. Thank you.

Hi everyone, I have an Acer Nitro 5 which shuts down when it is on stress CPU+GPU or using while the battery is not fully charged or just gaming, I've tried removing the battery and still not working, it is not getting hot because I have it with undervolt profile and changed thermal paste recently. Then, every time it shuts down I have to wait like 6 minutes until it wants to turn on like a old car. I suspect a power problem but I don't know where or how to start.

What is that stuff that starts changing colour on the corners of the GPU, it can't be the same flux because that stuff evaporates or gets blown away.

I have the same model but it doesn't have a graphics issue. The issue in is the motherboard there is on power

Are you not going to clean the flux off?!?! My god man!

Hello, after watching your videos, I can safely say I have become a professional technician. I have one request, do you mind making a video on a laptop that’s quickly discharged the battery power? Preferably on a Connex or Hp laptop

HI SIR.

nice

I have a dell 1525. It had white screen issue. Opened it and found the u49 MOSFET(3.3v) wasn't outputting. Shorted it and LCD started working again. Next day, the backlit would come on but no display. I tested using another motherboard and confirmed the LCD was fine. Something wrong with the motherboard. External VGA works. Lvds output not working. Can someone guide me with clues.

👍👍👍

Salut meștere !

This will fail after 1-6 six months. I always change 2001 and 4026 AMD with new ones. I use this method only for diagnostic purposes.

You can hear the Windows 7 sound because it's been upgraded to Windows 10 from 7 :)

cracked ribbon, or unseated connector

My laptop has the same problem do you think thats its my graphics card also I commented on your most recent post and my hard drive works I went to a repair shop and they told me it was my motherboard I bought a new one and the same problem occurs

I repair like this be4 but after 2-3 week problem come again, better replace the graphic

👍👍👍👍👍👍👍

Hey good evening, i have an asus laptop with the same problem... Only backlight, but it works normally with an external monitor (HDMI), do you have any suggestion?

Very good.

I have the same problem with my current Laptop Sony Vaio E Series model Vpcee31fx Is there a way to get get it fix permanently??

Maestre ,tot timpul ne inveti ceva nou
