If I I had that programmer I would also be flashing the bios on everything! Great video Sorin, I have learned so much from your videos, you are a credit to the repair community !
That's the problem. Since Sorin got the bios programmer now everything is a bios issue :D Made me laugh but what can you do, always need an excuse to test the new toys.
I have to agree each time I have received or purchased a new tool I was very eager to use it even if it wasn't quite frankly necessary. I do believe a little bit of that may have contributed to what happened but I know at least for me when you see something even if you know what you should be doing there's always the experience that gets in the way where you think well if it's the video doing this this is what happened in the past or something along that line and totally sidestep you're normal logic and troubleshooting theory and method. That being said I greatly appreciate each of these videos Sorin!!! And speaking of that someone had mentioned about having edited or cut videos and I will say even with a incredibly quick computer and encoding device and internet connection it still takes a bit to upload to youtube especially during high traffic times. And that's not even including the time to if you will re-encode if he doesn't edit it and just tries to upload it if indeed it's not some funky encoder from his camera....
You are so sincerely describing everything, giving us more opportunity to learn... This is so rare, and I think less than 3% videos on RUclips are like this... Very nice to watch...
Sorin! hello from argentina! I would probably BEFORE, doing the bios upload, try to see if there is VIDEO from HDMI, to see if is any problem on the screen. If not, continue with other steps.
I spent several hours diagnosing and repairing a problem where the computer would pass bios testing, but would fail while booting. I reinstalled the operating system, but on final boot it would do the same thing. It turned out to be that the ram needed to be removed, and reseated, then the computer would boot into windows.
Yes I understand once you have a new tool you want to make the most of it and get your moneys worth😅. Thank you for sharing this vital learning lesson to locate the root cause, which is to start with the basics process of eliminations before moving on to the more advance process.
You know sir, we waiting for you as a member of our family closed to us get travel out of our home, all members of the family wait for you behind the dore, we respect your honesty, knowledge share, and we hope be on good shape always, thank you for your time
I think that it happens to most techs doing repairs on devices. We all hope for the quick find/fix on a fault based on experience & knowledge. Then it ends up turning into a bit of a rabbit hole because we train ourselves not to be defeated and it was right in front of you but by assuming what it could be or trying too hard you miss it initially. It's going to happen. We learn best from our mistakes (most of the time) 🤭 and that's a good thing because no one is perfect😳 ... including the 'experts' that are out there.🧐
When I bought a nice eeprom programmer I started flashing/reflashing/dumping everything... btw right now I have a lot of DUMPS that can be useful on future :)
@Laboratorio Assembler: The same thing happened to me when I bought the RT809H. I kept Bios and eMMC NAND of any TV that arrived at the workshop. I spent 3 or 4 weeks experimenting (I'm slow to react) but when I felt that I had become familiar enough (essential) I put it back in its original shipping package. Another way of saying it, currently, for me, is like having a "missile" when you are a "pacifist" country (but it's better to have it). All the best.
😂😂😂it’s funny how he put the fault one on other slot and suffered changing bios but as students we learn very important lesson thanks your content are always amazing
When diagnosing a laptop, you always start with basic stuff, like replacing RAM, disconnecting all perhipals, and so on. You aren't supposed to start flashing BIOS as first resort.
Hello Sorin, please don't cut so mutch content out on your way to find the fault. I (we, your follower) have learned so mutch during your fault analysis in the past. Even you are on the wrong way, we get so mutch information and experience by you.
I am not even going to waste one second pointing as I have so many times done nothing more than take a device apart and reassemble only for it to work right then and have to explain to customer what it was.... Something, for sure, in his trail here, could have also or either been the issue, but since, ahah!!! He didn't swap the sodimm a 2nd time, we will never know. Still is no different in the fact that he says learn from your mistakes and you can build a good routine with which to troubleshoot and fix things quickly!!!👍
At this point he's just wanting to use the bios programmer every time. He's really stretching it to make it so. "When your only tool is a hammer, every problem is a nail."
@@electronicsrepairschool you can. In India you've a fan base sir. I started from nothing other than the basics but overtime by watching your videos I've learnt lot of stuffs from you. Keep going sir.... Love from India 🇮🇳
I've got an hp 15-da1005en it was working fine just put it in my bag near a magnetic ... when i took out try to power on... it do just on then off in one second never on
it firstly passed from the repair shop! that would probably made you feel that it couldn't be ram issue. but you definitely feel the urge to play with your new toy, right? ;)
Thanks for this video and on behalf of all other videos on this channel, I much appreciate them. So my question on this video is, when you copy or read the original bios file and save it on the computer, that means if it's the one faulty then you've copied everything including the faulty within. Then when you write again using the same file saved earlier, how does it work ! Like am trying to figure it out, help me out, anyone !??
one of my device's slot also not working and i even changed slot and it is same so i think these slot directly connect to GMCH that means GMCH has some problems about reading/writing data
One more thing, you can learn from other's mistakes and still do the same mistakes not long after ;). Been there and done that :D. So, even though I fix stuff, I like to watch others fixing to remind myself what not to forget :D.
but wait what if it was the bios and the faulty mem card?!??? who would guess that. like he said it was from the local repair shop im sure they checkd both mem s
Watched the PCH soldering video also. that was awesome. I have a small question regarding that. when blowing hot air from the bottom what will happen to the capacitors underneath?
they will be fine. The surface tension will keep them close to board even when their solder will reach melting point - so they will not fall down. And if that capacitors are SMD but ceramic type (small brown rectangles), then they will easily handle that high temperature. BUT if you have there Tantalum smd capacitors (large black or yellow rectangles), then they can easily die because of high temperature applied too long time. The worst scenario is when you have aluminium electrolytic capacitors (silver cans) there - because you have to take them out first. Due to high temperature they can swell or explode.
@Radek Stopyra: I'm not an expert but DDR4 memories work [1.2 V ‒ 1.35 V] at least the ones I know of from Kingston and Adata brands. I did not see the measurement of the memory that in the end worked but I honestly think that with your comment you found the fault. Thank you very much for asking because with our comments we all learn. A brotherly greeting to Poland.
@@carlosgarciaoropeza5480yes, my question was like a joke because as you said Sodimm ddr4 works at 1,2v . But each memory has SPD chip, which contains model name, frequencies and time profiles. So that chip has higher voltage. BUT Sorin should explain it why, 2,5 is there instead of 1,2. He shouldn't say ram memory has 2,5 and it is find because is not in theory :-) Anyway I don't know for sure now, if that 2,5v is from spd chip or maybe if the memory is bad, as that stick was bad, so maybe then the spd chip negotiate wrong voltage and maybe then instead of 1,2, the memory gets 2,5. I'm not sure now
@@hakimbwire3429 yes yes, it is logic, but he should explain it why there is more instead of 1,2 right? but in other way, I don't know now if there is a possibility, when then memory stick is bad, and that one was bad, then maybe spd chip is bad or the communication is wrong and maybe the board deliver wrong voltage to whole memory stick - for example 2,5 instead of 1,2. What you think about that?
@@Radek__ Thanks Hakim. Thank you Radeck. Next time I get an HP I'll do a lot of random measurements on that RAM. Again, thank you both for your kind responses. Greetings.
I have an Acer that RTCRST at pch was low on voltage. Suspect pch bringing it down. I inject 3.3v and seemed to fix and allowed to boot but no screen. Similar symptom to you. Tried a couple bios and ram. I'm thinking it's pch problem for mine.
one of my ram slot also doenst work i think my problem is GMCH chipset because i see in my model schematic slots are directly connect with GMCH chipset. According to device model yours can be PCH yes.
I know you dodgy, but frankly your style and self-confidence make you the best Electronic Repair School Teacher EVER!!!

lesson learnt... always start with basics, anyways the satisfying part is the other shop missed something so simple too!
Mistake is part of success..ur a legend Sorin
The other repair shop miss it also!
I can't believe!
Sorin! hello from argentina! I would probably BEFORE, doing the bios upload, try to see if there is VIDEO from HDMI, to see if is any problem on the screen. If not, continue with other steps.

From the moment I started watching I thought it could be a memory issue....however, it is still a good video post...thanks Sorin
I caught that mistake! I was like,...he is putting his eggs all into one basket assuming the other is good 😂

Sorin, put that RAM under the microscope. I've repaired so many RAM's. Usually only a resistor or resistor network is faulty.
Do a video on it. Would be great to see!
Make video
I really appreciate if you make tutorial for ram repair
شكرا لك .. كانت عندي نفس المشكلة وبعد إزالة الرم اشتغل بشكل سليم ... Thanks 😊

Just because you have a new toy, you don't need to use it every time you're forgetting the basics 🤣🤣
I thought the same when i saw you play with the memory! I had this problem but i reolaced all the memory stick in first place and it did work!

every time wanna use usb format or bios put it on the power cable side post thats a tip
I always use my own RAM memory to troubleshoot RAM issue. And that is the first thing i do to troubleshoot no display issue.
Good job mate 👍

ddr4 ram voltage supposed to be 1.2v not 2.5v .
Stupid BIOS should POST with message defect in RAM. What is wrong with these companies anymore.
good work very informative
it's weird the other shop don't try to change the ram
one of my device's slot also not working and i even changed slot and it is same so i think these slot directly connect to GMCH that means GMCH has some problems about reading/writing data

Wait. This one came from a repair shop? And they didn't check the RAM?
Good point. Still, Sorin needs to put the programmer away and get back to basics.

what can i do
Danke
but wait what if it was the bios and the faulty mem card?!??? who would guess that. like he said it was from the local repair shop im sure they checkd both mem s

Hi Sorin, What pointed you initially in the direction of a BIOS issue rather than a screen fault?
What about repairing the RAM? Sometimes there is a physical damage, scratched, missing components. I was successful in some cases.
hp laptop are the best
looks like the repair shop didn't check the memory 🤔
Mr. Sorin, what camera do you used on top? I think you have a better camera on top than in the microscope....
This month we starting with BIOS invasion 😂 lucky this one is easy done :D
show us if it's possible to repair a ram memory...
