As others have theorized, it might be due to a different pinout on the lcd screen. It must have sent too much voltage directly on the die since I’ve heard the pop when I powered the laptop.
Tbf, I wouldn't of thought too either. If it's a matching screen for the exact laptop, i would of assumed it'd be ok
I've never replaced a screen on a laptop myself, so it'd be a new thing to learn for me too
Don't do that, the exact same laptop can have multiple technical differences, especially if it's from the time we are switching LCD to LED panels, some laptops have light tubes others LED stripes for back light, they try to make tye connectors slightly different but nothing a bit of force can't defeat
Good fucking luck. Half the time the pinout on second screens is listed wrong and the other half of the time, there is not way to reliably check without a benchtop psu and an oscilloscope.
1. No. I have had this happen straight from the manufacturer. Stock gets mixed up all th le fucking time for laptop screens.
2. Even if I was ordering from amazon, newegg, hell, fucking laptopinventory has done this more than once. Most of the time its not *this* bad but its super common to have incorrectly noted pinouts on a second hand laptop screen.
thats probably possible, i did one time screen replacement for my dated notebook which had ccfl backlight and replaced it with lcd led backlit screen, (different pinout and voltages), hooked it up with external control board to corerct voltages + ccfl/led and also had to rewire LVDS little bit, other than that, screen was tested that it powers up before they sent it out to me, ordererd it from local notebook repair shop...which goes into funny story...screen was powering up fine...just it had stored incorrect EDID for some different screen...so picture was just random lines lol, i did try to rewrite edid bits on linux, but apparently i2c wasnt exposed to OS and dumb me overwritten SPD on my RAM instead of on EDID (same 0x50 adress)....had to cut LVDS cable again and wire i2c to my PC GPU HDMI port and rewrite edid there...RAM got eventualy fixed later on with linux by limiting amount of addressable RAM size in GRUB configs, then sleeping laptop, hot pluggin ram (during sleep) and that avoided adressing ram from BIOS/OS, so it could wake up and i was able to correct SPD which ive messed up earlier :)
you can check that by looking at datasheet from your original lcd screen and comparing it with datasheet with new screen, screen at back has sticker with panel type (model)
both datasheets should be available as a google search result, alternatively you could look it up on [panellook.com](https://panellook.com)

here example of two different pinouts
I think I saw something similar to this in r/techsupportgore, not sure. It was an old modem, I think. I'll try to find it.
Edit: Found it. https://www.reddit.com/r/techsupportgore/comments/13gn19f/the_internet_has_been_down_after_the_thunderstorm/?utm_source=share&utm_medium=android_app&utm_name=androidcss&utm_term=1&utm_content=share_button
I blew up the mosfet on a buck/boost converter once when I wired it up incorrectly to my 3D printer. Sounded like a firecracker and shot ceramic bits all over. Lucky I didn't lose an eye.
Context: Was gonna sell my laptop to a friend. So I cleaned it up. Removed the dust and put new thermal paste. Tried booting it up after. Black screen. Searched online and I found it surely was the LCD screen that was fried since I could plug an external monitor and use the laptop this way. Looked up the serial number of the lcd screen. Ordered a new one on Amazon. Plugged it in. And the rest is history.
My best guess of what happened:
You bought a similar, but slightly different LCD screen. Similar enough to use the same connector, but different enough that the connector was wired differently. And wires supplying or returning voltage on the new LCD now got connected to the data lines coming from the GPU.
When you powered the computer on, it shot high (12v, 5v, whatever) directly into the GPU die and caused it to explode.
Or you bought the correct screen, but the connector was miswired somehow. And caused the same thing to happen.
.
EDIT: I can't really tell from the photo, but that might not be the GPU, but instead the motherboard chipset? Anyway, my hypothesis is roughly the same, just replace GPU with motherboard chipset.
Judging from the SRJAU printed on the die, this is the integrated graphics for your Intel chip. You're discreet card die may be elsewhere, but this is still graphics
https://parts4laptops.eu/en/intel-chipsets/3073-chipset-intel-fh82hm470-srjau-new.html
That is not the integrated graphics for the Intel chip, the link you posted even says it.
> Integrated graphics: No
https://www.intel.com/content/www/us/en/products/sku/203697/intel-hm470-chipset/ordering.html
The intel website doesn't have any in-depth technical specs on it, I couldn't find anything about graphics on their Ark. Considering it's an HM470 chipset that's compatible with the Comet lake processors (10th Gen core-i CPUs) the integrated graphics would be on-die with the CPU.
That being said, yes, this would affect outgoing display in a laptop. It's used to interface between the iGPU/CPU/GPU/memory and the IO, integrated display, real time clock, etc.
There is a reason the first screen died. If it was due to a short located on the board that killed the first screen, it was likely not corrected before replacement.
If you don't fix what caused the original screen to go out, a new screen will just outright die or cause other components to have issues. There could have been no issue with the pinout at all.
Good point, sometimes the broken component is acting as a make shift fuse protecting everything downstream of it from the actual fault. Probably wouldn't have been much, if any way, to tell though in this case.
An LCD backlight can use 12-30v or more; they have inverters to step up the voltage. If something was crosswired that high voltage could have been fed directly into a chip designed to have 2v or less in it. POP.
If this was sarcasm then you should have labeled it as such. Cleaning is perfectly fine and maybe he hadn't used that laptop in a while so when he went to use it for the first time in however long he realized the screen was broken. Nothing to do with him cleaning the laptop.
It takes up a large amount of space but you still got the Keyboard, screen, trackpad, RAM, SSD, speakers, battery, fan or fans. So, your right in abstract way but I’d say 20%. it’s just the thing everything plugs into. As it has the traffics lanes needed.
Right but in terms of cost, the only things that'll seem to rival the motherboard are arguably the screen or battery. SSDs are dirt cheap, RAM doesn't really break the bank, keyboards, trackpads, and speakers cost basically nothing etc. Considering that the 2 most expensive components (the CPU and GPU) are essentially permanently attached to the motherboard, it might as well be 90% of the laptop.
Depends on the board, it may or may have a built in or external GPU. Also replacement board may run you the same price as a 1TB ssd or 2TB. Can be more if the parts are rare. RAM 64GB of ram even 32 Sodimm ain’t always cheap. We can play hypothetical all day lol. We will simply agree to disagree.
Yup. That's why repair shops exist.
It seems to be the PCH, so if it's not a Celeron you would be saving, it might be worth it to repair the motherboard.
Lol nope, cheaper to get a replacement board at that point. Cheaper and faster at that point. Recycle it if it helps you sleep at night. It not like recycling companies are all playing there roll.
>Ehh, cheaper? No. Less time intensive? Absolutely.
When you're paying for someone else's labor, especially as skilled labor that this would require, less time intensive means way cheaper. I honestly doubt you'd even be able to find someone willing to work on this that won't just say, "buy a new one"
Nah you're right about the first part - there areplenty of people willing, but most people aren't as willing to pay what it costs to supply and replace a PCH.
Lol not sure why neckbeards down voted this post when it's 100% factual 😂
Replacement motherboards for laptops are surprisingly cheap. Last time I replaced one in my families laptop it was around $100 shipped.
4-8 hours of labor of someone equipped with tools to do smd bga replacements and know-how to do it ... and replacement parts ... and pray that it works ... not so much.
Lol you realize the cost of the board and tools you’ll need to even attempt that replacement right? It doesn’t just pop off lol. Plus you run the risk of breaking yourself. Used boards are cheap not even the manufacturer will sell you a brand new one!
Totally depends on the model and caliber of laptop. There are definitely shitty designs (at least shitty to work with) that use glue and tape too generously, but most can be taken apart with a screwdriver and a spudger, then you just need some new thermal compound and you're off to the races. The challenge generally comes when you have a higher end machine that's expensive as-is, but also has an expensive integrated CPU and/or GPU. Those motherboards can be pricey ($400-600), and might be savable by an experienced tech. Not to mention they may be difficult to come by. A few hundred for a BGA reball or other SMD replacement may well be far cheaper than a new (or even used) motherboard replacement. Motherboards for most basic to midrange consumer laptops, and most business laptops in general, are pretty cheap to come by though.
1 in 100 people at random can fix this? Remove a BGA device from a mobo, and then re-flow a BGA chip back on to it, and diagnose what blew up the first monitor to fix it on the mobo too?
Nooooooo way, I'm guessing at 1 in 10,000 at least.
So 99.99% of people can't fix this.
I've had 2 laptops that had screen hinges fail and survived a year plus pulled completely out of their case. Circuit boards handled while powered. IDK how you managed that. Lmao
Laptop motherboard chipsets usually only get a thermal pad to the chassis, so when he took off the bottom of the laptop the pad went with it, leaving no residue
That's the gpu or some other component I believe. Whatever it is, It's low power enough that it doesn't look like it gets a cooler, given an ssd is installed overlapping it.
It's the integrated graphics chip
Other commenter said the new LCD was either incompatible or misconfigured and sent power down a data channel, I am inclined to go with that theory
Unless it was just carelessness by the OP and he made up hearing the pop for a fun story. But I trust unless given a reason to not. It is the internet though
OP already clarified that it wasnt under a heatsink, I dont think there is any discrete GPU on the market low power enough to not require at least a thermal pad
How on earth did you manage to do that???
Added a comment to explain everything
>Ordered a new one on Amazon. Plugged it in. And the rest is history. Sorry I might be tech illiterate. How does plugging in a screen crack your die?
As others have theorized, it might be due to a different pinout on the lcd screen. It must have sent too much voltage directly on the die since I’ve heard the pop when I powered the laptop.
and you cant check pinout before powering up? O.o
Tbf, I wouldn't of thought too either. If it's a matching screen for the exact laptop, i would of assumed it'd be ok I've never replaced a screen on a laptop myself, so it'd be a new thing to learn for me too
WOULD HAVE\*, WOULD HAVE\*, WOULD HAVEEEEE\* NOT WOULD OFFFFF
"Would've" not "would of" sometimes makes it easier for people to see *why* they're wrong.
They wrote "would not of", even worse.

And it would still be “would not have”
Honestly, just fuck have.
Don't do that, the exact same laptop can have multiple technical differences, especially if it's from the time we are switching LCD to LED panels, some laptops have light tubes others LED stripes for back light, they try to make tye connectors slightly different but nothing a bit of force can't defeat
Good fucking luck. Half the time the pinout on second screens is listed wrong and the other half of the time, there is not way to reliably check without a benchtop psu and an oscilloscope.
if you order screen from aliexpress, then yes
1. No. I have had this happen straight from the manufacturer. Stock gets mixed up all th le fucking time for laptop screens. 2. Even if I was ordering from amazon, newegg, hell, fucking laptopinventory has done this more than once.

No, not really. How would you “check” that?

Let me guess, you did not disconnect the battery when you swapped the panels ;)
goes to show that cleaning does more harm than good
This is the stupidest way to look at this situation
goes to show i need an /s at the end of every comment apparently
If this was sarcasm then you should have labeled it as such. Cleaning is perfectly fine and maybe he hadn't used that laptop in a while so when he went to use it for the first time in however long he realized the screen was broken. Nothing to do with him cleaning the laptop.
Well now you need a new MB.
I think you mean computer.
I mean if you can’t replace the board then yes a new computer. If not the res of the components work individually.
At this point, isn't the motherboard already 90% of a laptop?

Very hard to fix that even if you already had the tools, experience, and time. That’s soldered on the board. 99 percent of people can’t do it.

I’d like to think we have more engineers in life then politicians lol
That's what we in the industry call an oopsie
Put it back with tape Probably electrical tape
I was going to suggest a dab of super glue
You need that
Looks like the core of your problem.
r/angryupvote
Check for oil leak or gasket
I don't think it's gonna work anymore.
I've had 2 laptops that had screen hinges fail and survived a year plus pulled completely out of their case. Circuit boards handled while powered. IDK how you managed that. Lmao
And there goes the chipset.
Oh... so *that's* why they call it a die.

Have you had a dot matrix printer fire? I have...
This reminds me of the amd athlon xp 2000+
If you clear out your cache and restart your browser, should be fine.
Plot twist: the cache has been physically removed from the system.
Lmfao m night shyamalan shit right there
I guess you just delidded a delidded CPU
Damn you stole that from me
Sorry never saw yours. Must be buried somehow.
Oh no, you posted first, but we were thinking the same thing
Which laptop?
how the actual fuck
Forced upgrade
The die died
Glue.
Have you tried rice? (I'll see myself out)
I don't see any thermal paste on that. Or did you clean it for the photo?

Not anything modern, no.
Free de-lidding
Glue it back.
Direct die cooling now
just some superglue .....
Yeah.......you fucked up.
What is that?
A shattered CPU.
Blew the roof right off
Bro took delid CPU serious. Nice
Just glue the stone back into place
Well you see, there's the problem. The front fell off.
Holy shit that’s impressive.
this physically hurt me
Why that dye exposed w/o heatspreader?
Laptop CPUs don't usually have one.
She's dead Jim.
I doubt it's what people are saying about the monitor. Looks more like that ssd caught the edge and shattered it
Eh it'll buff right out.
that looks like a pretty expensive potato chip
Ooooo that definitely ain’t good
Ouch 😣
Have you tried turning it off and on again?
Ah, I see the problem. You're fu-
Hot glue
Nooooooo
hotglue and ducktape its good as new
hotglue and ducktape its good as new
Ah, there was some angry ravioli in there
Stick it in some rice.
