Graphics repair on laptops or how you can fix your graphic chip 

Honestly. I don't know how the fuck he can work like this. JEE...Zus!

And he was on a rush...sigh

he did that to avoid the sudden thermal drop and to stabalize the chip into position with the melted lead, cause heat can do two things on a chip either expand or shrink and with that chip exposed to an environtment with alot lower temp itll cause it to crack/break / or sometimes pop like i did with mine lol and i do precaution with it like slowly lowering that temp while pulling the hotair away but it did cracked ived learned it the hardway like sorin did ive done gpu reballing the same way now just dont forget to change that thermal pad or thermal paste cause theyd be dried sometimes cause of the heat

indeed, thank you

you may never receive an answer

@@Armagheddon-ux1gx lol 😂

Yup. I would not do this. It is NOT a proper fix. Unfortunately.

Wouldn't he be able to just replace that gpu with a new one? I mean just desolder it and solder a new one back up.

@@thingshappen9199 sadly you should change mother board on this onboard shit my laptop fucks and i cant do shit now

@@thingshappen9199 reballing a new (expensive) GPU to a laptop MB is to expensive, not woth it.

The gpu had a die though, it could scratch it.

HDD? Keyboard?

It basically 'revives' dry solder joints around it and somewhat restores conductivity. It works, I've tried it on bigger Gpus but they'll need to be replaced eventually. Maybe 3 months, maybe 6 more months. Depending on average usage time/intensity.

replace the screen or replace the flat cable

Time for a new motherboard/laptop.

I've done that and the temperature decreses about 10 celsius degrees and the laptop lefe expectancy increses a lot. Of course, depending how do you use the laptop

simply disable it from device manager, my dell Inspiron's gtx 850m crash on every games with "application has been block from accessing gpu" shit and now I have to use intel hd 4600.

ed nja defective screen controller.

hi, full air

Hey,what did you do ??? Have same problem

you can't :))), but if is a overheating issue and a dedicated graphic chip, probably its a graphics issue

Thanks Sorin!

u r welcome

Just watched this today. I wish I had found this video a month ago because I had the same problem.I eventually fixed it but by replacing the graphics chip which is very difficult. One comment. You can generally tell it's a graphics chip problem and not corrupt Bios or memory because the hard disk light will act like a normal boot sequence and when it stops will continue showing activity when you hit "Enter" as Windows continues boot sequence even with no screen lighting. With BIOS and memory problems you won't see this sequence of hard disk activity indicated by the hard disk light in almost all failure modes where no video is visible. Again, great video.

what can i do if i have 2 graphic card but one is disappear and not even recognizes in device manager this happen with my laptop toshiba satellite L50 and the graphic card that disappear is nvidea m950 4GB memory but the intel graphic card is working fine. please help me with this because i'm tired try to fix it

u short to ground 1 pin at a time, eventually u find the power button and it works

ranny day those kinds of chips don't have a surface to transfer heat like the casing of a cpu does! So, they go with pads to act as that intermideary mateial. Also! It depends on the pads u use. Some specify to apply some thermal paste and some don't! But generally, you don't because it ends up being a waste! Those laptops are never really used for heavy tasks, anyway! The real thing is to keep a clean airway and to keep the CPU at good temps always! Also! That pad on the back of the chip will help a lot to dissipate heat to the keyboard! So, next time you open up your out of the shelf laptop for dust blowing, put one of those guys in there!

did you solve the problem ? same happened with my laptop also ... mechanic saying motherboard need to change

@@ashsean6818No, I'm sure this is the board problem !

Connect external display. If still no pix then its GPU chip.

In my experience, if on the secondary screen its working fine, most likely it's your laptop lcd screen

thx Ill check iy

Can I still remove the gpu voltage for the discrete gpu even if it is still functional? Mine works for about 30mins before getting too hot and then the screen gets this distorted color schemes

Hi. I have this issue. My motherboard is dead, I ordered a new one so I see this as a challenge. My motherboard is Asus K53SD rev 6.0. I turn on my laptop, power button is on, caps lock is on, little led light (marked as light bulb) is on, but my screen is black. Fan works normally, I can hear the hdd spinning. I tried all those easy fixes; switching ram, taking out cmos battery, holding power button for a minute, etc. I tried the external display via vga and hdmi. Nothing. So my suspicion was right from the beginning, dead graphics chip. I disassembled the laptop, took apart everything from the motherboard and tried the bare test (just motherboard with cooling system connected to external display); still nothing. I even tried cutting power to graphics chip and creating it to UMA (I took out it's voltage regulator); still nothing. I checked my display (learned that from one of your videos), there is 19v, 5 and 3.3 power supply. Any help would be most appreciated. By the way, your videos are great learning material. I learned alot. Thank you. I use this electronic tinkering as an escape from my stressful job and my stressful life. It calms me down.

please give me a reply if you have found a fix for that...we have the same issue

James Domaboc, reflowing your graphics chip is the solution. I did it a while back, and it inhaled new life into my dead motherboard. I just checked it, works just fine, but I already installed a new motherboard. My old one was killed by the heat. This time I cut out 6 cm circle inside a bottom laptop cover, just below the graphics chip. Installed a small 5v, 5 cm diameter cooling fan. I covered it with a stainless steel grill I scavenged from my old desktop power supply. Soldered its power to USB slot. Now fan starts when I start my laptop. No more overheating.

Vaso Vulović Find that same chip on EBay, take it to a guy with an IR machine and a clean fucking workspace (Guy's workplace is a dump) have him replace the graphics card by desoldering the old one and resoldering the new one, and have him clean the board and fan. Should work like new. If you can, improve the RAM.

Whatever happened - happened. But in the future build the habit of changing the thermal paste (maintenance) every spring and you won't have an overheating laptop on your hands. It's like a car - you can't just buy it and drive it without an oil change. And once you forget and do serious damage, the solution is never as cheap as regular maintenance. ;)

Not that easily, since the gap is too big and the pressure too low for thermal paste usually. The elasticity of the thermal pad is required for constant and proper contact hence heat conduction.

Nope. Best bet is to use eGPU if you got Thunderbolt3

if is the backlight, you will have picture on screen

The problem is not on the solder balls between chip-motherboard, chip itself it's broken.

depends, if the laptop died because of a bad overheating , i we will give 3 months

😂😂😂

The motherboard chipset

@@filenotfound__3871 Oh, thanks! 😃😃

Back of the chip, 7-10 sec

Electronics repair school awesome thank you

You are absolutely right, but the way Sorin did it too is also correct IMO. I would use your method for a desktop CPU, but for smaller chips like these and those found in graphics cards, I tend to spread the paste out evenly with a small piece of card before reattaching the heatsink. Golden tip: Too little paste will not allow for adequate cooling. Too much will just yield the same result as applying the right amount, so no worries about applying too much. Arctic MX-4 isn't conductive compound as far as I know, so no worries about causing shorts. By the way, this is just info that I have gained over time.

It won't last long.
