The 'no fix' videos are much more engaging to watch. Whenever I see Sorin stumped, it grabs my attention because he's usually like a terminator - unstoppable and methodical. Seeing him struggle makes me sit up and pay even closer attention.
Sorin, struggle more please people like us contents like these . Lol.
Stumped no way, dead laptop 100 💯. We know the laptop is dead 😂
When Sorin starts grinding holes into the motherboard, I'm like OMG NNNNOOOOO!!!!!! However, I am amazed that he got the thing working.
YES!... I agree... so many systems are interconnected, if one part of the chain is not up to par affects the rest of the system. ...the moments where Sorin leans back and says: "..why it's not working?" ...then you can almost see and hear him going through all his "brain files" looking for an answer... then "Bam", he tries something and reports: "...we have picture!!!" ...(the crowd stands and claps and cheers!)... 😁
yoy didn't try to remove the display conector on the m-board and check with the hdmi. i noticed the pin camera on the laptop is off center. comeone opened the lid and fiddled inside there aswell. Well done anyway Sorin . Legend as always. Thank you for your genuine content. All the best
Nice to see how you dealt with this one Sorin! Interesting to see how it ended, great video 😊👍
Hey joey! I watch your vids
very true
my face is so welcome again! 😆
Great video. After reading some of the comments i think you need to do a part 2
You defiantly spent enough time trying to fix this. Hat off to you you went further than most people would have
It's like a two hours lab experiment. Fixable or not fixable this is the question...! I had a few like this years ago and sometimes frustration sets at the end. ... Thank you Sorin for the video.
As someone else says, why did you disregard the screen problem? Sometimes hdmi output not functional until windows joins the party, right?
Sorin, since the caps lock turns on. Then it means the laptop is definitely working. some devices wont display on an hdmi output if it is on the bios menu. Hdmi output only works on Windows. Sometimes only when the graphics driver is installed on the windows OS. You can try disconecting the lvds cable or install an ssd with a windows OS. Then try the hdmi output again
Yep, can be, but that also means screen is faulty.
Looks like someone dumped a bag of faulty parts and assembled this laptop.(Shop?)
@@nikspanakis yes it can be the screen. Or maybe the display circuit is not right. Like the 3.3v or 5v line for the screen or lvds is missing.
We all learn from this.😊
@tjaytony if that would be the case then he would have backlight with no picture, which he hadn't.
@Tribes11 No, i have fixed lots of gaming laptops with a missing 5v line on the lvds. It does not have backlight or picture. It would just seem like the screen isn't connected.
The switch for the video signals can be faulty, too. The 3USB chip. I had a broken one. Not shorted but open signals. Exchange was successful.
I received a laptop from a customer that Sorin couldn't repair. It ended up being the negative reality inverter.
I noticed that the camera at the top of the bezel seemed .....offset which if it is could mean someone had it opened who knows but it could be unplugged inside and some laptops won't post to hdmi. It could also be a faulty lcd all together I would check for backlight voltage too. Love your videos and your character
Looks like a Frankenstein job lot of bad parts sold as "faulty for parts only" perhaps. Dead mobo, batt, kbd, and screen? How? Smells like a ripoff.
So close to an "EP Repair" (EP = EZ Pizza)... It's just one of this things... you did awesome to bring the system up to a running state... just needed to sort out what was/ was not happening in the video department... Thank you for another awesome video and large chunk of knowledge! :)
Sorin hi there hope you are well.. Curious about after you came so far spent 2 hours why at the end didn't check resistances voltages of gpu chip and vrams? Could be a shorted vram chip or mosfet..
He did, this video is edited and shortened. The real time spent is 2 hours+
Thank you so much, Sir. this is one of your best videos; educational and informative❤
is it pointless to disabling dedicated graphics? ( i have no experience in laptop repairing )
Hi Sorin thanks for the video, KB9022Q often short! I replace them regularly on MSI and Asus laptop. On Asus laptop it would be easy pizza because no need to program, just empty ENE it will auto program.
and what about ite chip? also autoprogram?
I'm from the US and I purchased thermal pads , solder and liquid rosin from your ebay store. Excellent products 👏. Maybe you can still get some 🍕. 😂
Actually even if the board is working properly the display will not come by hdmi as acer dose not display bios on hdmi . So I would like to suggest to put the nvme disk and then put the HDMI cable
yeah lots of laptop show bios/uefi only on integrated screen
Surin keep it up so many peripherals bad on a single machine still you attempted it, no words but great. Today was no picture but there is always "we have picture" keep it up sir
The temu fan is back from holiday.
As Thrilling as "The Silence of the Lambs".
The silence of the EC chips -> "I do wish we could chat longer Clarise, but... I'm having an old chip for replacement."
Sorin, I write a lot of negative comments but it is nice to see that some jobs are hard or almost impossible. Thank you for posting this and keep the good effort. I love your channel a lot
Ahm just asking what about if you disconnect the screen then trying the hdmi?
hi Sorin what its the programing machine model you use?
Sorin , Years ago I've had a similar problem on an ATX (pc, not laptop) MOBO: NOT brain-dead (swapped CPUs, RAM, GPU, etc. to check), like at the end of the video (after the EC chip repair), but no display, no boot, no BIOS = BOOT-loop.
The MOBO i had would NOT boot into bios with a dead BIOS battery, for some god-forsaken reason (pc= plugged into the wall). I "solved" that mystery when i said "F-if!" and put the meter on literarily everything, until i found 0.01V on Bios Battery
Could It be the same case here?
When you use the chip reader to read, then copy files from it to transfer to another matching chip, do you have to delete any existing files on the receiving chip before the transfer, or does the utility program automatically delete any info / files before reloading it with the copy files? Thank you
Good job Sorin, always informative. Just no “fixed it buzz”.
Some laptops have no display without a bios battery including 3 of mine, try to change it
Sorin, I'm sure you have already shared the info about the infrared thermal camera you use? Would you mind sharing it again?? Many thanks.
Happened to me 2 weeks ago... HP laptop i7+ nvidia... the shop replaced the screen... and the integrated GPU died. Lost 2 hours for nothing.
Your videos are so interesting that It doesn't matter if you weren't able to fix it...
Is there voltage on the screen connection? I had a bad HDMI but the screen connection was good. I used only hdmi because the screen was cracked. What happened is de HDMI was getting Shorted or something happened, when putting a new cable and was not working anymore. I was assuming it was a broken laptop. It was coming on an no picture I tried a different screen and it worked.
Kindly which site do you get bios bin that are clean.
Wonderful job as always. You have surgeon hands. I would have tested with some compatible screen just to make sure. But, yeah, the repair job would end up being really expensive.
Nice work, Sorin!
In the case of a dead integrated GPU, is it possible to switch to the discrete GPU definitively? I believe there's a BIOS setting for that... so one would have to edit the BIOS file and flash it like that?
nope
PART 2 IS WAITING....lol 😂👍👍. hello from jakarta
We all know different things, that’s what makes the world go round!
Hello Sorin. You can make an ldo with current limiting or in case of too much current goes to cero. Remember you must modify your power previus supply to remove such protection.
Did you check 3V3 on screen connector? Also was there backlight?
no point doing that. external monitor isnt working either
@@SirasPK you are right. But the HDMI port does not need power to output video? Only graphics signal?
@@SirasPKExternal video won't work on some laptops till you boot into Windows
Congrats for the 400k subs!
Nice video I have one doubt oppo a18 slightly bend what solution sir
could you disable the vram power supply for the graphic card and try the internal graphics
14:52 you can always consider applying heat from underside, works for these pesky LCD connectors on flex cables.
This is a gaming laptop, multiple layers, the amount of time needed to keep the hot air under the board is more risky than a quick 480 upfront, he can always protect the connectors with aluminum tape, Teflon tape or kepton tape like he did. It's still risky to melt the plastic components however it'll not damage the board on a layer level.
Another thing to consider is that the other side might as well have some delicate component like another connector (not this case I believe) or another IC.
@@Tribes11 indeed, i missed the very valid here fact that it's gaming board with tons of heat capacity. But if it comes to components not being meltable on the other side, surface tension of solder compound will hold firmly even TO252 components ;)
hello sir . i watch your every video but i am confused, you check the coils and say that its good or bad but i could not know how much ohms it should show in the coils. could you please explain it thanks
Looking for resistance that indicates a short.
There was missing a coil too at @7:00 (power supply of GPU?)
Hey, I replaced the thermal paste on my acer nitro 5 but it doesn't turn in now. The blue light (battery indicator)comes on for a 3 seconds but the nothing comes on after that. When i keep it on charging the orange light which show power turned blue showing full charge. Can it be fixed ?
I suspected the EC chip. that number you said type:9020 and 9022 the keyboard and screen doesn't work also the motherboard version should also aligned with the bios. I have the once have the same issue with the bios like the same laptop the gen but two version of motherboard have two different bios. I install version 1 on version 2 motherboard the power button starts to blink errors.
Sorin if you put a new bios batery in i have seen some one do that and the picture came on as well try it ?maybee ?
Everyone has a specific amount of knowledge and practise. Just normal. It's even honorable to understand if the own level is not high enough and send the defective item to somebody else for the hope of repair.
Reminds me when i got faulty MSI laptop and only specific EC firmware got it to show picture.
you are very kind wizard...
Try to reprogram another firmware (as a last resort).
You are a professional! Nice job!
the ec chip is doing it's job, no point in doing that
@@geovani60624 he means the bios
Disconnect the LCD cable from the mbo, and then . try via HDMI cable. Also try with another clean Bios extracted from exe file
some dust from manufacturer process
The TH-cam Tech owes you a Pizza for your effort.
What was the Spark from
how about removing the mosfet that supplies power to the graphics chips ?
I have watched an awful lot of your videos (which are great by the way), and the one thing I find really bizarre is the amount of laptops that get sent to you that are really dirty. Why would you send something to someone with your grubby (germ ridden) prints and other gunge all over the screen, case, etc? How hard is it to wipe something with a damp cloth before sending it? I don't get it. People haven't learned much from Covid!
I can never hold it against anyone if they refuse to attempt a repair where they know they might make things worse that someone else could fix and this job sounds like one where that's true
what about the lid sensor? faulty keyboard make me think of liquid damage ... check carefully the board. Use MATS to check GPU Ram also (but usually you get backlight when is a vram issue).
mats does not work if laptop dont have mux switch
Ok that is fair but who is the other youtuber who couldn't fix it and why didn't he go this far already?
Thank you Sorin very apprecited effort anyway , maybe some other tricks can be done like isolating the gpu like before or trying the hdmi without the screen connector on , or if you get some other time later to finish the job and probably trying another firmware because it sometimes does work if you just leave the things that went bad for another time.
it should be working! the mb just wasn't checked properly by Sorin...
after 2h of work better scrap it than sell it cheap !😂
are we sure the chip is programmed with right one? i mean yes the laptop starts but nothing else is working. i could be wrong just a guess
Tomorrow we will make up for this with 3 proper nice pizza.
Sorin... special humor sometimes. 😂
I would like to see the other youtuber's video, not to be mean or anything, but instead to see what was done before you got it. No point to bashing or being hateful, we all start knowing nothing.
Thanks for uploading this video mr Sorin
Liked and subscribed
You're the best as always. Greetings.
Helo Sorin , try to disable the power of the GPU By unsoldering the coils of GPU to force shut down the gpu , or mosfets of GPU.Did You measured the BIOS boot sequence signal
with osciliscoop?
Sorin the people on the form commented on the EC firmware with "no display", so maybe you need a good firmware ?
I saw those comments also, but couldn't figure if he downloaded that one or another that was supposed to work :-?
Is it possible that the laptop won't work without a functioning battery? I thought you might try to revive the battery with the battery analyzer at some point.
Yes! I bought my pd3.1 charger brick, because i was not able to power the dell boards
I think you may be right. Seems odd that the battery is locked.
Wait aren't laptops supposed to work even without battery
No I don't think so as I have been using acer laptops since 2006 and used different laptop but everyone works without the battery even my current acer laptop also
Yes but it is turning on, I don't think this is the case to be honest
What a fight !
yes yes acer netro keyboard has a bridg its missing on this laptop and i think in future you will need a usb monitor to just teasting good job man
I think I saw two of the Rams removed from the graphics card😅
I have a feeling that if you had used another EC and Bios Dumped from the same laptop, it would work
Master sorin ❤. Can you give us EC chip programmer lesson please... 🎉
Your legendary in repairing circuits ⭐⭐⭐⭐⭐
23:23 lol that's me on how iam working lol
Обычно Сорин предлагает отключить видеочип - это не долго. И посмотреть будет ли картинка…
так там может у cpu нет встроенной графики, разве он что-то будет показывать если отключить видеочип?
Some boards are just ment to be gutted.. and somewhere all of those replacement boards need to come from. That may just be one of them..
Love your videos Sorin :)
Must turn on with the HDMI connected, keyboard and with a windows SSD. The bios will detect the second screen. Don't know if you disconnect the lvds cable could help.
Sometimes HDMI only displays with monitor disconnected
You are always the best
Kindly upload a video on how to fix GPU's. I have 2 gaming laptops, Lenovo Legion and Lenovo ideapad, and both are faulty with GPU
Dziekuje Sorin!!!!!
For me it is fixed. Maybe it is not worth the time (and not have the parts too), but trying a different screen, keyboard and battery (it is locked?) something could happen
I have an asus with same fault shorted 3.3v ldo dead ec chip and shorted pch lol and yes the ldo chip gets hot when you plug the power
i think he should of tried different LCD or disabled the GPU coz i found some laptops don't usually output to HDMI on boot
A sum what sorin need to try
- placing 3v bat
- hdmi on a acer will propably only ouput with windows starting
- test circuit around the intel chip
That constant 1 mA , i dont trust..
You tried and i agree it sucks ! but you can`t win them all.
classic somebody tried to clean the laptop with battery plugged-in. realtek codec and screen are dead, maybe gpu too (that's why no hdmi picture).
The GPU is faulty for sure.
Proper Calibrated Repair😎😹
very good
Acer Nitro don't work on hdmi on bios view.
Screen is damage...
well, you should have checked all the 3.3 and 5v devices, because they're all burned somehow. including keyboard, chips etc. graphics vrams prob are cooked too.
no, if they are cooked the laptop won't turn on , the EC chip check them first if all good it power on the laptop so since the laptop powering on this means all power supplies good
Proper no pizza at all.
sometimes it's really hard to do a repair that was coming from another tech.. just sayin' 😊✌️
Probably screen and nvme faulty and goes to Bios not displaying on hdmi, try your nvme that has windows and hdmi
2nd video please
Maybe just faulty screen as well
