- Repair Shop Fixes One Problem but Causes Another! Can I Do Better? I don't have amazing luck with fixing laptops but I love to experiment with fixing them. So I'm giving this one a shot after the seller said they took it to a repair shop to fix a charging problem but, after getting it back repaired, the laptop screen stopped working.

Just wanted to address the fact that I could have plugged in an external monitor BUT my understanding is that these take a special connector to do that and it's one that I don't have. I did try to just plug a monitor into the ports on the sides and that did not work. I should have added that segment to the video but I didn't. Thanks for all the suggestions in the comments and I'll give some of them a try.
I just wanted to ask that. 😄
even if you hook a external display it may not show anything until you configure that... "one" of the ways to do that is to install a OS on another laptop, with windows on it and select the a 2nd screen as main display and remove the disk/nvme/ssd whatever and use it on this broken laptop, sometimes that works to know if it is the display, but, honestly, to me this laptop is powercycling over and over, maybe a short, or maybe that bios or bga chip is toste.
@argcades it has only one SSD and can't be upgraded with another one as far as I know. I never had this model in hand. But it should just be as easy to select the external display on the keyboard, still unsure if that fully functions after seeing the video, it could be a power cycle. Reprogramming a Bios chip isn't that hard, just look up some guides. But on the other hand, this is a hardware guy and not a software guy.. so, he would need to learn it. But since that chip is replaced, who knows what's on there? Maybe he should get his hands on a new bios chip for this model and see if it fixes anything, a preprogrammed chip that is exactly for this model and with a fresh installation of Windows with the specific software and hardware drivers for this laptop.
the charging port or the usb c port with the weird connector around it will have a display output. using a usb-c to hdmi cable should do the trick
Got one of these working at home. I think i got video output from a cheap usb c dock (satechi). Can double check but won’t get to it until middle of next week but let me know if that would help.
Steve, I know it's been fixed until it's broken now but a good test, if the laptop has an external display port (hdmi etc) would be to plug in an external monitor and make sure you're getting video output at all.
i was screaming that ,well too late now
I came here to say this too. If you give that a shot, I'd love to hear the results.
Yea I would have done that before talking the whole unit apart for sure.
In my years of experience I have never seen the motherboard working that well except for the screen.
I mean sometimes it's the conector.
But this diagnostic was over complicated.
Also on laptop to check if the battery is the issue plug it in with out the battery plugged to see if it powers up
Glad I'm not the only one saying this.
I do so love the fact that you include videos where attempts at repair weren't completely successful. Thank you for all you do!
I appreciate that. It's hard to upload them because they aren't as satisfying but that's real life.
@@Tronicsfix I always find these funnier, though. The ones where you fix them are always satisfying, but "fixing something until it's broken" will always be funny.
@@Tronicsfix I disagree. On the contrary, those ones are the most interesting to me because of the suspense and you'll never know what's gonna happen which makes them way more fun, as opposed to always expecting a fix beforehand
When working with laptops always disconnect the battery first. There are so many different cases when people unplugged or plugged in the display cable and fried PCH, KBC IC or display logic board and you can easily avoid it by unplugging battery first. Chance of that happening is slim but it can still happen especially if you put display cable at the wrong angle and short pins. I really love your videos!
I will take this advice, really useful!
The best part of watching your videos is that you are 100% honest in your skills and ability to be able to successfully repair different electronic devices. Your honesty in this only goes to show that you are always willing to push your skill to the next level, even when you have some failures along the way. You are someone I look up to when it comes to your willingness to not only show the process you go through to try and fix different electronics, but your also willing to accept defeat when the electronic equipment is not able to be fixed, or is out of your scope of skills. Its your true honest nature that I appreciate the most, but your teaching ability is superb. Thanks my brotha, and I look forward to many more videos from you in the future.
Fixing things until they are broken is how I roll! Also great for learning sometimes. 😂 That's what I keep telling myself.
Lol!
I have limited knowledge of laptops, but when a desktop turns on but don’t post it can be lots of things other than the monitor. Like RAM, graphics cards/chips, corrupt BIOS and so on. Don’t laptops usually have a Displayport or HDMI for an external monitor so you can test that…
That's the thing about engineering though, eh? Even if you can't fix it, you still do your best and it's always a plus because you learn what is/isn't part of the problem when you encounter it again! :D
True. Sure woulda been nice to fix this one though
@@Tronicsfix I bet haha! Esp that feel after being focused for hours steadying your hands and everything... Can be pretty unsatisfying :/. Still, from a viewer's POV it was a great video! And from another engineer's POV, it's always fun/educational to watch others work! :D
Maybe the repair shop assemble the screen without unpluging the battery, that may cause to blow up the fuse in the LCD side of the board, you can uncover by peeling the tape off.
Fuse? On a screen? Never heard of a screen with a inline fuse before.
Since you didn't have a schematic, I'm surprised you didn't try an external display first to verify that the machine is at least working before going down any other paths. Either way, great video as always!
Hey! I’m doing my part!
As long as people accept that sitting down drinking a cup of tea is doing my part. 🤣😉
We're not justing 'watching' Steve we're 'willing' you to fix it !! Embrace our combined power !!!
Great to see honest videos ! RUclips is littered with too many fake repair videos so its nice to see real world stuff !!
One suggestion to ensure the laptop is working properly, connect an HDMI cable to it and see if it projects onto an external.moniror or your tv. If it does work then It is simply a faulty screen, if it doesn't no matter what you do, then there may be a bigger issue
Came to say the same thing.
@@cfh5221 Looking at all the comments he won't make that mistake again.. 😀
Hey man, I appreciate both the effort and the willingness to share it with us. Even though this one didn't work out, you mentioned how you were getting pretty decent and putting some of those cables back in. So there is that!
always a bit disappointing when you dont end with a fix but its still good to see how you went about diagnosing the problem.. maybe a similar device needing repair will pop up and can use this as a donor.. too many expensive parts there for e-waste.
One thing you missed out straight away was you didn't shine a torch onto the screen to see if it was just backlight issue. The other thing is, is that screen set as the main screen? is it booting to another display port? If no success, send it to Sorin, sure he will find the issue. In fact, it would be nice to see a collab with yourself and Sorin.
Always enjoy the videos!
I have a suggestion, maybe next time you could try plugging the laptops into a monitor to see if they are booting up into windows. Feels like that could help you know if it’s the screen or the board itself.
I was just gonna comment this
@@aelaan12 ME TOO
Didn't see this comment, so I did too. Great minds think alike👍🏻
I guess that's a lesson only experience teaches you. Or random folks pointing it out on youtube.
You'll fix the next one! Great video and attempted repair. Thank you. 😀
Those videos make me feel better from when I fail to fix something, but as you say that`s life. Recently just changing my thermal paste i managed to short the ribbon cables for the RGB light on my ROG laptop because I thought not unlugging the battery won`t be an issue :D
Oh, no! Yeah, disconnecting the battery is pretty much always a good idea...as you found out
I guess we all have to deal with failure sometimes 😢
Like the videos of new stuff that you might not be able to fix but fun to see you try and what it is like inside these things . Ty
I suggest to attempt to measure the lines from the power input on the board. How much charge is left in the battery for instance. Measure to where the screen connector is placed on the motherboard. Get a general idea of what could be wrong instead of speculating about the bios chip. It is easy to find code for that, even if you download the bios from Asus and extract the binary part. Last suggestion is to inject a little bit of power and see what lights up. That the keyboard lights up is clearly an indication that power goes to it. The seller claims they got it back and it powered up and screen worked, but that is their word, clearly it is not working since the day they sold it. 600 bucks is way too much for a tablet/laptop in this state, but I know you calculate different.
Some laptops need to be plugged in, and then turned on after they've been taken apart. I don't know why, but I have seen that on laptops I've repaired. They just won't boot on battery alone the first time. HDMI port is a good idea too.
I have the older Flow X13. Powerhouse of a laptop, but the CPU runs way hotter than I'd like. My old Dell never got above 75C, the Asus can get up to 90 when playing games, and it usually sits at 85.
Yeah these are pretty powerful, if you can keep them cool.
My HP Pavilion does this too, idk what HP was smoking when they designed the cooling system cuz they decided to cool both the CPU and GPU with ONE fan. It sounds like an airplane and the CPU hits almost TJmax temps even with a cleaned heatsink and fresh paste
Sad that you didn't get any picture of the screen. Here are something you can try out:
Check if you have image on external screen. Get a thunderbolt/usb-c to HDMI adapter, and check if that works.
If you don't have image on the screen, the bios may be faulty, due to the blinking white light. Try to hold F2 down, and press the power button. Continue holding for several seconds, and you might be able to get into the bios. If not, you probably need a bios programmer.
Good info. Thanks for the comment
@@Tronicsfix if you also have a flash drive that blinks when data is read/written, yiu can check if the machine is trying to post or not, and see if the cpu is "braindead" or not. If no blinking/activity, then the bios may need a reprogramming/replacement
Shucks. That's a bummer.
It's got to be frustrating when manufacturers don't facilitate repair friendliness.
Super frustrating
10:47 I, we, the royal we, man!
Great episode, Steve, keep ur chin up.
We are not just watching we are providing spiritual support. Knowing that so many people is going to see this will make you work at your best right? 😁
Es una pena qué no pudiera ser reparada esta laptop, fue una gran clase Syeve; gracias
Great Video Steve
Thanks 👍
Not a computer repair person but have had some experience with weird situations like this.
If there is an issue with the display but firmware is ok, disconnecting the screen from the motherboard and plugging an external display should show it booting, if it does not than it is possibly a BIOS problem.
Seeing some rework done around the BIOS SPI could offer some hints, and if the SPI was not written properly or corrupted, some OEM's offer a bios update on their website that is the full SPI image so all you'll need to do is download it and flash it to try.
First step would be to get a flash reader/programmer with a soic8 clip (like a dediprog SF600) to dump the SPI and see that there is a BIOS image in there to begin with.
I hope any of this helps! :) hope you get that machine working again
10:45 not TronicsFix calling us all out 🤣🤣
The laptop most likely has a USB thunderbolt out for a display if there are no HDMI ports so you should try hooking it up to an external display to se if it works.
Just watching! I was yelling at the screen the whole time.
Great video! Have you ever worked on/considered working on Intel NUCs or other mini PCs? I have one with a non-functional m.2 slot.
I was so expecting a happy ending
Me too! Such a bummer
i would suggest to check all voltages, starting from the input and leave the battery disconnected. Apart from the charger voltage, you should have 3.3v and 5v on the board. Check voltage on bios ic also, 1.8 or 3.3v. If you have an oscilloscope or a simple logic probe you can check if there is clock and data signal on bios ic when you connect the charger. Reprogram EC chip, it can also be corrupted and most shops don't have the tools to reprogram it. If EC chip and bios don't mach the laptop is also dead, for example if they programmed the bios chip but did not reprogram the ec chip with the same version. Reprogram EC and BIOS the same time with the file that comes in the same package. Almost forgot, BQ chip or charging ic, if there is slight variations with the number or letters, it can sometimes have a completely different pinout. Check what should be the original ic and solder it, maybe the shop replaced it with the wrong type.
When i worked at Dell tech support we had a ability to run diagnostics to test the screen even if we werent seeign anything and the user would just hear beeps if they didn't respond to the prompt. I wonder if this laptop has something similar? Probably best to determine of it gets past post and maybe there was a code trying to be displayed. Best to test with HDMI for the time being though!
When you tried to turn it On it was blinking with White light.. In my case that was a problem with the Ram!! If you manage to get it to the stage it was before, check there it might be the same thing for you as well
So at 7:43, it appears that those two chips are having issues. There does not appear to be a good connection on the chip on the right (looking at the screen as a viewer) the two top feet does not appear to have a good connecting point. They look like the connection is just barley hanging on.. Also it appears that if. they did a repair that they made a hugh mess of it.. Again, t hank you for what you do. It has inspired me on doing some thing that I have not done before. I was at VidCon in Anaheim, I wanted to say HI to you.. Starting feeling ill and left. I did speak to the staff from BW100.
Why didn't you try HDMI/type-c(DP) output before disassembly?
great video as always
but the story of that laptop is pretty shady
that's a ROG Flow Z13 GZ301ZE as shown @1:22
with a manufacturing date of January 2022 and that thing is sold with a two year warranty, so
1. why was this sent to some repair shop instead of asus (since it not taking charge has to be covered by warranty)
2. (kinda the same as 1) why sell it if the screen won't work instead utilizing the warranty
did the seller "find" the laptop on the street somewhere?
I have to know, how often do you have to go back and review the footage on tear down to make sure you get it all back the right way? I am always re-taking things apart when I goof up the disassembly. I should record it for my own notes.
Very rarely. After you do a bunch of this stuff you start sort of understanding how things go together. That's not to say I never forget something, it just gets easier over time.
@Steve, You won't regret doing a collaboration with @Electronics Repair School, chanel
He's such an awesome guy "Sorin" and very very very good at repairing laptops.
Please send it to him so he can do a video
I would check the connector on the screen side.
19v should light up the leds.
not if the screen dont get the enable pin for the backlight
With that many 3.3v it is propably on. Not many lanes needs 3.3v
4 displayport lanes, and a few enables.
Hey maybe try to Hook it up to a monitor!
So then you can Check if the laptop itself turns on completely.
Does it have hdmi? U could connect it to a tv to see there are any signs of connectivity
Try hdmi if it has it if not it should be display port over usbc.
Maybe they was playing around with the bios chip. Try to reprogamming it if you get some life signals. That model doesn't have HDMI?
Did you try to plug the hdmi from the tv? I had the same issue and i was able to found that my screen was broken
Hey man, love your videos. can you fix graphic cards? all the best from trinidad and tobago
Could most likely confirm if it's video or the screen with an external display. And tbf to the seller, I also had a rog laptop where the screen randomly gave up one day and needed replacement
Do you fix up monitors by chance? I have an ROG monitor XG35VQ that needs repair but I have no idea what’s wrong with it. Turns on but just a blank black screen every time I turn it on. No start up, nothing. Tried different power cords still the same thing
If it has a light on it to tell you when it should be on and its on, but no screen showing. Then get a torch and shine it onto the screen to see if you can see anything on it, it , if you can then the backlight on the lcd has died and you need a new backlight.
What kinda microscope do you use for this stuff? I gotta get ke one of them for fixing old game cartridges 🔥
He has all the soldering gear.. A collection that rivals even my own by far. And he didn't think to test the monitor via the HDMI connection before tearing the whole thing apart.
Did you try shining a flashlight at the screen? If it is just the backlight that isn't working you will see an image where the flashlight hits the screen...
Hey steve have you ever tried to fix a Surround sound receiver? I have a Onkyo receiver that wont power on anymore. If tou want to try and fix it you can have it the price of shipping.
The only thing I would have done before opening it up( and you might have, but you didn't mention it. ) would be try and attach a monitor.
is there a RAM card that is faulty? when i swaped the RAM for more ( 4 to 6 ) it wouldent turn on the screen but the laptop did turn on. Than I removed that RAM card it worked again...
I was wondering where can i find liquid metal for the ps5? All i seem to be finding os thermal paste.
that white led flashing twice when you try to turn it on? LED Status indicator?
Ive certainly seen plenty of machines that behave just like that. and whilst i cant find anything specific for this machine, a couple other ASUS motherboards suggest this style of flashing could be GPU related, either not present or faulty. which would certainly tie into the display not showing.
I’m assuming that’s an error code or status indicator but can’t find any info about it
I had the exact same issue with my ROG flow. I sent it in for warranty repair and when I got it back the display didn’t work anymore. It turned out the backlight for the panel stopped working.
Interesting. Thanks for the comment!
@@Tronicsfix Have you connected the laptop to an external display to see if it works? That's how I found out it was the backlight. I also used a flashlight on the screen and I could see images.
if all voltages are present i would suspect corrupted bios, can u send it to someone to program it or do u have a programmer?
hello Steve, if they they out the chip of the bios, you can try reprograming them, just in case that they didn't know how to do it :)
if the bios its not correct the pc will never show signs of life :) sorry my bad english, greetings from Chile
can you plugin an external display to check?
Doesn't it need the ssd installed? Isn't that where the O.S and software is?
Just asking.😊
Every success/failure is part of learning curve, we need to fail sometimes 😂 but I like that You allways challange yourself with something new 😂 personaly even I whould not repair this, last thing I whould try is burn new bios but that whould be my last trick in sleve bc it has all voltages and seems to be working...
did I miss it but did you try with external screen if it is booting?
I love your video ❤
Thanks! Glad you enjoyed.
those diodes top left of charger chip didnt look to happy
I saw some capacitors missing on that board because I saw some solder spots on the board so I thought it was missing capacitors. If you want you can look.
Often they are intentionally left missing. The capacitor is for activating features of other models so they don't have to reengineer the whole board.
you should have plugged in an hdmi cable and a screen to see if you have picture, this would tell you if the graphics card and the computer in general are working fine
my rog screen also stopped working out of the sudden,it just died, head it's an Asus factory fault, I can still use the laptop connected to a tv with the hdmi or external monitor with thunderbolt cable. If you can connect to a monitor to see if the laptop still works...
I love your video’s
The rollers on my ps4 slim make a clicking noise when they move I took it apart to clean all the dust and dirt and I cleaned the lens and the rollers and when I reassembled it the rollers started making that clicking sound what should I do
did you test if you have any shorts on the board?
Watching you take stuff apart a lot of times makes me think "I would have bailed by now".
Always test a laptop where the screen looks dead by attaching it to a monitor before you assume anything with a screen. That's where I start that way you have a better idea if you should look at the screen itself or not.
in my opinion, the bios in the motherboard has spilled, so you need to upload a clean bios and transfer the serial numbers of the laptop and the code from Windows
Did you test it with external monitor?
The flow looks like a more repair friendly surface.
Send it maybe to Daniel Rakowiecki? I think he will try to fix new things like that.
Check the memory and see if it has tokens on the board. Change the tokens if there are any
Did you try an external monitor?
Nice laptop
Yeah, these are nice.
the blinking light is an error code look up for the service manual for this computer.
Will you ever repair some atari. (lynx or 2600)
Yes
Hello!
You shouldn’t make anything with matrix connector until you unplug battery! You can easily shorten data and power pins with your multimeter or when you unplugged ribbon
What happens with an external display? USB C to HDMI is easy to find.
Seems like one of those things that you can come back to at some other time when more information is available. Sucks that there are no parts, manuals or information for you. :/
the laptop camed with windows 11 and winodws 11 has startup sound maybe if you could hear that sound it would be the laptop screen and try pluging it to an external screen using hdmi
Do you have any interest in trying to fix a baby monitor camera? It looks impossible to open
Could it be that the repair shop unseated the VGA chip? This would affect the screen.
Why don't you just connect it to external display?
You should connect an hdmi just to see if the screen is the issue...my opinion...good day
You fixed it to death. NICE
Why you not try whit a hdmi cable?
Plug the laptop into a TV or monitor and see if video comes up on it. That would let you know if it's a bad screen.
I think there will be a revisit on this 1
