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!)... 😁
Hey Sorin, everything i know about electronics , i learnt from.you. and by Gods grace early next year am opening my own repair shop..all thanks to you,, so far i have repaired 3laptops,, 4subwooofers, 2TVs, and two radios....you know who is my teacher?YOU. Soon i will repay you Inshallah..am.yiur biggest fan from.Africa...KENYA
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
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
@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.
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
So close to an "EP Repair" (EP = EZ Pizza)... It's just one of those 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! :)
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
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
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
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.
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 ;)
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."
Hi Sorin! Just into 10 mins in, was thinking if you removed the E.C. and also BIOS chip from donor board maybe not need to program the E.C.? Am still watching, Excellent work, Legend!
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?
I feel your frustration Sorin, anyone that has spent years doing electronic repairs hates admitting defeat. Bu sometimes the time and parts used starts to go well beyong what you can expect a customer to pay. Fingers crossed that your next one is an easy pizza.
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 )
Interesting video. I have a similar nitro 5. Mine is working right now and Im selfishly hoping this isnt a common failure for the Nitro 5's (mine is technially the "v" but it's a 5 so yeah), even if you never fully figured it out.
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.
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
Thanks very much. Nice knowledgeable video after long time. I think better you trace the last signals like DRAMRST , PLTRST ect because U come to very close
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.
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.
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.
Hi Sir, you have used hot air with 470 degree with ram memmory inside it can be that you damaged the connector or ram memory check that also. Thanks for the nice explanation and video.
I think Sorin should have another go at this Nitro Based on the current consumption board looks to be posting and behaving, He should verify a USB mouse lights up to confirm the unit is posting. The dead EC chip is a clue, this often happens as part of a cascade failure starting with an LCD issue. Either the LCD slipped or the cable failed, and took the EC chip with it. This unit maybe working properly, but have a bad internal LCD. (Most laptops wont display HDMI out unit the OS loads, and this maybe in a windows startup repair environment) It would also be a good idea to check Diode mode readings and voltages at the LCD connector, it may have a dead 3V power supply to the screen. It is also possible that another signal that interfaces between the PCH and LCD has failed with a short circuit. All of these issue are stereotypical of a cascade failure that starts with a screen or cable issue. Im sure with a little more time this one is fixable, and hope Sorin revisits this no fix.
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!
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
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).
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?
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.
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
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.
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 ?
Something tells me at least a try on the screen, I mean, checking the display connector and changing an alternative screen. Coz how the hell would you get caps-light but no display. It's all a lesson that its a lot i need to learn. Cheers Boss
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.
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
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.
Hello Sorin, I'm scratching my head wondering why you have to programme the EC chipset yet you got it from a presumably working laptop? Please let me know.
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?
If Sorin had more time, I believe he would figure it out. Maybe there is a problem in EC or Bios, in BIOS bin. There is around 22,000 code for EC in some lines. 128kb🤥
I think its fault lcd or lcd flex. Its can be no backlight (not always see if you use externall lighting) Acer not always can boot on HDMI !!! If you check on HDMI first disconnect lcd flex and restart. Try another EC dump. Check VGA BIOS maybe is there. If nothing help probly fault GPU/VRAM this can also be verified by desoldering VRAM.
The reason HDMI doesn't display is because it's a 'software controlled' output. It isn't just ACER. My Dell does it. The driver has to load and switch the output on. Old analog VGA would display even at BIOS. Even audio sockets are driver controlled these days.
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.
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

You defiantly spent enough time trying to fix this. Hat off to you you went further than most people would have

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.
I received a laptop from a customer that Sorin couldn't repair. It ended up being the negative reality inverter.
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.

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.
As someone else says, why did you disregard the screen problem? Sometimes hdmi output not functional until windows joins the party, right?
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.

14:52 you can always consider applying heat from underside, works for these pesky LCD connectors on flex cables.

Thanks very much. Nice knowledgeable video after long time. I think better you trace the last signals like DRAMRST , PLTRST ect because U come to very close
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.
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.

Some laptops have no display without a bios battery including 3 of mine, try to change it
Disconnect the LCD cable from the mbo, and then . try via HDMI cable. Also try with another clean Bios extracted from exe file

maybe the GPU ... at 25.26 you plug the screen connector with the power-supply !

I saw those comments also, but couldn't figure if he downloaded that one or another that was supposed to work :-?

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?
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
If Sorin had more time, I believe he would figure it out. Maybe there is a problem in EC or Bios, in BIOS bin. There is around 22,000 code for EC in some lines. 128kb🤥
I think its fault lcd or lcd flex. Its can be no backlight (not always see if you use externall lighting) Acer not always can boot on HDMI !!!

Check VGA BIOS maybe is there.
If nothing help probly fault GPU/VRAM this can also be verified by desoldering VRAM.
