Lenovo Legion 5 Laptop Dead after Screen replacement - Is it Fixable?

[@lolidasterner414]

It's hiroshima after all

[@maxpax2338]

This time, even worse.

[@kpelectronics]

Absolutely

[@1BigBen]

[@punker4Real]

7:07 the GPU isn't going to work too

[@TheKosssteK]

My lucky guess is that this fuse blew for a reason, maybe there was something else wrong and it caused the fuse to blow. When repair shop replaced the fuse with a wire (clearly not a proper calibrated one :P) it didn't pop like it should and forwarded high voltage straight to the PCH. I have no idea if it is possible cause I only gather knowledge from YT videos but it seems logical to me at least :)

[@cookiemonstr9071]

Do you have any idea, i just tried to unpin my acer laptop display when the battery is not removed, and after that I see its charging and power indicator showing for 2 sec, no back lid, no fan turning on, no keyboard light, and after 2 sec the indicator turned off. Any idea ?

[@FUJISHIR0]

I think like you do !

[@Luissebb]

The fuse blew because the user shorted that high voltage line to the chipset data lines (and shattered this), this is very common in the laptop repair business (Always disconnect the battery before you do anything inside your computer).

[@Customer22374]

@@cookiemonstr9071 your pch is gone , sell it for parts and next time don't do it yourself pay someone $50 lubor and save your self over $500 for new laptop or new motherboard . it pisses me off . I see this happen all the time from s tupid customers

[@cookiemonstr9071]

@Customer22374 I am thinking it to replace from genuine engineer, he is having proper machine to replace pch.

[@superconductives88]

This case demonstrates perfectly why bypassing a blown fuse is never preferred over replacing and finding the underlying fault. Fuses are there for a reason- to protect vital components.

[@kiwanukagerald7274]

exactly what i talked of the other time,replacing a screen with a battery still plugged in and boom blown chipset some times cpu,this mainly comes from shorting the 19v on the screen connector to data lines

[@winnieid2727]

Yup, fuse blown for a reason, very rare because of the fuse itself

[@cookiemonstr9071]

Same happnd with my laptop but its charging and power indicator showing for 2 sec then off.

[@andygardiner6526]

Yep, at 7.09 it looks like the gpu die was cracked too

[@sylvainc8146]

After such a quick intervention, the end credits come: Very Fantastic 😊

[@TheGameBench]

Had to replace the screen in my own Legion 5... these systems seem to have a common problem with a dithering effect that creeps in from the edges of the screen. However, when they said they left the power connected, I knew what had happened, but it's crazy to see that it literally blew the PCH in half. It also looks like the GPU die is cracked as well. I think it's a safe bet that the CPU is done too. This is going to be an expensive lesson for this shop. Seems they have a bit to learn.

[@Luissebb]

I saw a video where a technician replaced chipset+cpu (amd) + ec + bios + gpu + 1.8v power supply on a lenovo legion, craziest electronic job Imo.

[@David-mo8dx]

My English is very poor, thank you very much for the translation, it is very important, like everything you teach. The video of the camera with lens and not the microscope helped me a lot. I had certain doubts and they were all removed. Thank you, you now have a new subscriber.

[@youssefhany6555]

Before i continue the video ... as soon as he said didn't disconnect the battery ... i was like "yup ... dead pch" but i didn't expect it to be cracked pch 💀

[@TheAussiePipe]

7:07 GPU looked cracked as well?

[@mariesvilmy5680]

yeah i saw that too

[@ca3340h3993]

That's what I though too. We definitely have a "well done" laptop here.

[@davidlguerr]

It is not a crack, it is a hair.

[@Pieter12345pk]

This is what I thought as well, but it's a hair. If you look closely, you can see that the black line is above the cooling paste.

[@maklogetrich2378]

​@@ca3340h3993the store has to buy a new board, a new screen, what else

[@randomkitty2555]

I had a feeling something blew when you said it had a screen replacement. Tech 100% didn't remove the battery during replacement. They should've known that even when the device is off there is still 19v running through the LCD cable.

[@moepmanauto]

GPU looks cracked too.

@moepmanauto I sent in my computer 2 days ago ,I hope to get a good diagnosis my laptop has been giving me trouble since the day I boughtnit.

[@NBMSCH]

the question is; what caused the PCH to blow or partially damaged like that?

[@jasonthejawman5442]

Alex diagnosed perfectly

[@naj3hoth231]

I really don’t understand Most of devices or all of them are just dead and doesn’t turn on ? Is there any chance that you fixed devices that have audio issues or network issues like in Samsungs or apple, by the way I admire your work, im just wondering

[@iTCXtreme]

Battery not disconnected during screen change. I have same board with blown hm470 srjau bga chipset and shorted mp2143.

[@othmaneallinone9837]

What's recording microphone u use Mark...it has good quality

[@greentech1658]

Alex the rumble community is looking for you

[@MrEmiriv]

To me it's clear what happened there, damaged eDP cable, I have changed PCHs for this reason and yes, the labour is too much and the risk of buying a damaged (or preconfigured for another brand) chip is high, in my country it's still viable though. Some people keep using their laptops with damaged hinges, not knowing that the cable suffers, a damaged cable exposes the delicate data lines that come from the PCH, the CPU, a muxer or converter chip to the high voltage of the backlight, putting the chip AND the sccreen on the line of fire, even the webcam is not safe.

[@silversrayleigh1399]

Glad I sold my laptop and built a desktop. All laptops seem to be a time bomb waiting to happen.

[@zf8496]

especially very well packed laptops with heavy usage!

[@mkumar04]

may be ,heat is the main culprit behind less lifespan of laptop , laptop often reaches 100 degrees while desktop mostly 50-60 degree celcius

[@julianboyd8719]

Most laptop owners just aren't as responsible or as knowledgeable as someone who can build their own desktop. Most owners don't even realize you need to clean these out with compressed air monthly.

[@silversrayleigh1399]

@@mkumar04 Heat + the use of cheap components for some manufacturers = time bomb. Unless the portability is a MUST for you, go for a desktop. You'll end up saving money in the long run.

[@reeeeeee6416]

my acer e5 475 g survive for almost 9 year, but it does blow out ic charging because power surge at 2021, but its workin fine now, its just how the owner take care the device, cleaning dust on the heatsink and anually changing thermal paste, for now i build a pc for upgrade on the future

[@chihofung6860]

Replace parts on board without disconnecting battery, and then jump the blown fuse to force it to work? This is not repairing but destroying.

[@Peter-xu4fb]

There's a possibility that the PCH is gone, that's why I always laptop technicians not to be lazy, take out the battery first before screen replacement.

[@silversrayleigh1399]

It's not a possibility, it's indeed gone. Watch the video.

[@dhruvsingh9799]

he was not taking about steve he was saying it for the previous technician who worked on it

[@davidlguerr]

In fact, you should remove the battery to do just about anything. I had a customer who blew the PCH because he touched the CPU's heatsink on the board and shorted. He was cleaning dust on the fans with the battery plugged in.

[@orange11squares]

manufacturer bad design, 19V should not be on the LCD connector when laptop is off, it should be delivered via a mosfet that is off when laptop is off or in stand-by.

[@shadowopsairman1583]

Take batteries out regardless

[@apr2499]

What is the pch? The processor?

[@floridaapplemacprosinc.2224]

PCH is the old Northbridge and SouthBridge right?? Im finding a few of my customers boards have blown PCH and its not worth fixing, so this was good to see.

[@imcroni7346]

If I'm correct it's the southbridge. The northbridge is integrated inside the CPU

[@floridaapplemacprosinc.2224]

@@imcroni7346 I was watching an old Doctor Who episode where they talked about a processor that had circuits 100nm and they were all OMG.. and im watching that on a machine with a cpu with .14 nm!!

What kind of repair shop have the costumer but he didn't see the blow pch, i wonder... not to mention that he didn't disconnect the battery when he replacing the screen. Elementary notions.

[@MadMax-yq9ix]

I think the guy blew something while he was disconnecting things it still had juice flow in them.

I can remember when IBM laptops were top of the line. Then, Lenovo bought them out.

[@brianredmond4919]

What is a PCH ?.

[@TheAussiePipe]

PCH = Platform Controller Hub. The PCH controls certain data paths and support functions used in conjunction with Intel CPUs. These include clocking (the system clock), Flexible Display Interface (FDI) and Direct Media Interface (DMI), although FDI is used only when the chipset is required to support a processor with integrated graphics.

Power from the display's backlight line into the PCH. PCH can not handle 19V for sure.

What is PCH?

[@saijyo8549]

(Platform Controller Hub) is basically chipset for cpu. Managing usb, nvme and other stuff. If ur see crack on pch it already game over. Hard to find those new usually from donor board. take a long time to replacement and not guaranteed too fix it 50/50 change. Look the gpu die in 7:09 is crack too, Not worth it to fix that laptop.
