00:20 Thanks for the warm welcome with the right hand..🤗
24:57 the things will be more protected against the people who they try to replace the screen without taking battery out... 'Like me'...😂🤣😂
28:38 Aaawww... Look at your face, how happy you are.. The vital Smile after fixing something...
This video is inevitable. And thank you for educating us about the other diagnoses over the problem. I Learned new things, and the vital part is your description. As always Its awesome..
Thank you master.
God bless you...
Just watched your video on led screens so this video made perfect sense. Thank you.
Thanks sir for all the videos you are uploading. You are a great teacher
Thank you
Awesome and amazing video, Soin. Thank you much for sharing 🙏. Now I've learn about where to check on laptop when everything is on except imsge. Well done job Soin!
I am new to this field and got inspired by seeing your video classes. Please let me have your beginner's videos which will certainly help me to underst and about Laptops. Thank you sir
Very nice repair! Keep up good videos. Good information about the laptops. It's very hard to receive good information about those complex devices. Thanks a lot! :)
I love your repair videos. So informative. Thanks.
Another great video and NOT boring at all ;)
:))))) Thanks
bravo te apreciez foarte mult te urmaresc de pe toate conturile mele de google tine o tot asa, ma uit la tine ca la o emisiune la tv.Stiu ca esti roman de aia ti am scris in engleza , bravo!!!!
Multumesc
Please add subtitles too, thank you very much! Nice work!!
i will try, thank you
Wow I have this very Vaio with this very same issue...........now to take it apart and fix!
I was going to buy a new screen but not now until I replace that bloody fuse.
Many thanks liked and subscribed.
It was no boring job , I liked the video and I'm already suscribe. I'm learning a lot from you.
Thank you Master.
Parabéns pelas vídeos aulas, sou assinante de seu canal, tenho aprendido muito, brasileiro.
Thank you
Mais um do Brasil acompanhando este grande profissional.
You just taught me something - take battery out before replacing the screen - never heard of this before
That was a good one, using the 5 ohm. I would have taken a R010 or R020 current sense resistor, though.
Nice one boss, its very easy on you troubleshooting that kind of screen issue. I've learned a lot from your videos. More power and God bless
"another boring job" 8:20 sec lol
As usual professional job
Big thumb up
Those 3 who disliked the video must be the ''techs'' who blew up the fuse :) Nice job Sorin ...
Probably people who know that you cannot replace a fuse which has resistance in milliohms with 4.7 ohm resistor. It will cause power loss, and instead of protesting safely will burn PCB in case of overcurrent.
Sorin you saved me with this video!!! :D
Thank you teacher!!
i have this problem with my sony vaio,
tonight i will try to repair. regards!!
Solved?
Nice video. Lots of information
Excellent information Thank you
Thanks for your video, just located the fuse...its dead. So should be the solution to the no backlight problem. If this works you have saved me the cost of new laptop...Will let you know when I have swapped out the fuse.
thank you sir. i go to same way and repair difrent sony vaio. you are king...
Thanks boss it really worked for me
You are perfect!!!! Same issue on my laptop!!! TNX!!!
al menos me sirvió para aprender algo mas que solo cambiar el display...muy buen video!
i love this video,very informative
25:02 Same here. hehehe. Man you are the best!
nice repair bro keep it up
it is very very useful ,, Thanks so much
thank you
Great Video Sorin
I have the same problem,nice job.
Thank u so much sir .....Best Explanation ....... Love and Respect From India
Job fixed and well done, but what would be a better solution is to find the reason to the fuse blowing? I'd like to request and suggest a fully dedicated video on diagnosis and trace of what and why actually caused a blown fuse.
Reverse polarity?
In rush current?
Power spike?
probably someone tried and replaced the screen with battery connected or charger
On Toshiba laptops this never happened?
I did replace many screens with battery connected and always volt. Not sure if Toshiba laptops are different?
My exact fault , many thanks now i have a working laptop again for only €3.95
you are genius
Great Job!
very good info
hi great great video i have the same issue on a vaio fit 15A flip but i can't find the backlight fuse i messed up by replacing screen without removing the battery wich is glued on and screwed in
good video after long time.
you are the best...
I was expecting to see a thin wire aka "proper calibrated fuse" in place of the old one like you did with a ps4 repair, but what made that fuse to blow up in the first place a faulty screen most likely
U r a master, Thank You a Lot... even if i got same pb on a sony vaio (it's not a fuse but it's a PolySwitch), but it was a pleasure to watch the video cauz u help to develop my knowledge, keep it up ;)... Need Help on Lenovo B560, Can u explain how to fix when the voltage is correct, picture is correct, but there is no backlight??
Thank you, check those signals vled on and dimm
So there is 19 V, 3,3 V and 3,3 V goin to screen in LED backlight screen. Is there same voltages in CCFL backlight screens?
Thanks master it's worked for me
Soin, I've the same screen issue, but not on Sony VAIO, and however, it's on Asus Z240IC-H170. I sent to Northridgefix for no power on repair, but he couldn't find and then he shipped back to me, i cleaned off the CPU thermal paste and put the new one on. Then boom... it powered up but no image. Please advise whete i should check this issue on ASUS Z2440IC AIO. Thank you much in advance and hope to hear from you soon 😊 please 🙏
Really Gud job sir I like u very much
Hey Sorin. Another beautiful day and another great video. What is the kind of multimeter you are using in this video? The one on the bottom. Is it usb or pc-based somehow? It looked like you were switching from volts to ohms with the mouse. I know in the other video about your tools you mentioned the bench multimeter, but this one looks different. The display looks very sharp. Which one is it? Thank you!
I have a sony hk-8 motherboard and when i test with my multimeter ,im getting a short in the cpu section ,capacitors ,resistor,coil all short, is my cpu fried
First thank you for good video and teaching my question is do you bridge VLED and LED Enable together when no light or you give 3.3v each point ?
Bridge them together and do a jumper to the 3.3v main line
Thank You that is clear enough good job keep it up honestly I am a hobbyist and enjoy watching your videos every time I learn something from you.
Electronics repair school what wire specs do you use ?
very good job, easy one, if you know where to look.
Superb videos
good morning sir that good job
Very good, I have learned from you. but I have a question how can it service without schematics?
great job i like it
Salut Sorin referitor la ce spuneai cu referire la momentul in care nu ai grafica, nu ai lunima la display e adevarat insa sunt modelele de laptop care vin cu placi grafice dedicate cu soket pe placa de baza,acele laptop-uri daca grafica cedeaza din diferite motive acolo vei avea lumina fara grafica
Hello spring
Can u tell me how can I know the power button pins in the motherboard ,if I know the 3.3v should I short with...... or I don't want the 3.3v
Thanks
well done, thanks ...
sir, how find the 3.3v main line
with the multimeter, you have some big caps near to the screen connector
Good job sir
i have same issue laptop working then saddenly screen goes white then it goes black but laptop still working because the youtube video is still working hear the sounds playin but screen completly black
Why not clean the fan and heatsinks while its apart?
What is the name and model of your hot air solder station? Thanks
Good job sir, 😍😍
Thanks master
Same model, same problem. What would happen if I just bridged across were the fuse was ?
Perfect tanks a lot
Wouldn't the 4R7 resistor drop a few volts? Might be time to stock up on SMT fuses ;)
yes, that is why he didn't get 19V on that pins leading to the display....but it is not that important bc it is used for generating smaller voltage via dc-dc.
what brand you use of usb power tester?
I wonder what cause the fuse to broke.
I had a problem where the only working is my DVD/CD drive when I turn on my laptop ... others won't ,like display ,fan , indicator light etc..
please sir,what if there is light and no picture?what and where do you check?
hi..my sony laptop motherboard ic is over heating is TPS51427A WHAT IS THE PROBLUM NO POWER NO LIGHT
I HAVE A SONY VAIO ASSSIST 4197 69601 IS IT POSSIBLE TO GET A MOTHERBOARD FOR THIS MODEL
good video
good morning friend, what is the name of this component, please. thank you
thanks so a good realy
why is it so important batery volatage?
What happen when u dnt have picture and light.. but there is 19 volts plus 3.3v
sir.. may i know how and where to check the v core on most laptop motherboard?
on the back of the processor on the capacitors
The fuse replaced by resistor doesnt matter
nice.
i have got the same Sony vio laptop, i am having trouble with blinking LED light and not turning on, sometimes it turn's on sometime doesn't, getting hard-time to repair. and i am self learner , can you please help me out out to identified. what is wrong with?
sometimes your laptop is coming on and show on screen and sometimes its just coming on and nothing on screen ?
Hi i did everything.. i heated up my gpu, bgu chip on my sony vaio... but there’s no picture at all.. no light at all. The laptop boots fine fans are spinning but no success. Please guys would anyone of you help me out? Im stuck and I don’t know what to do anymore
Sir can you please recoment me some tools for starting level
Check the video with my tools, all my tools are cheap apart from hot air station and microsocop
Just sent for some wire glue, not got a hot hair gun. Please reply I'm doing it in the next week, soldering across to short out
Legend:)
Hi Sorin at 10:50 the 19vdc "always there" comment. What killed these people, the amperage? If so, how many amps flows at those points?
around 3-4A depends of the charger
Electronics repair school thanks!
Electronics repair school but if I need to check with multimeter and you recommend taking batt. out and adaptor how can I test the points at the screen section? Continuity, scale of diode symbol on multi.?
i said to take the battery out only when you replace the screen. Check with multimeter on volts with the laptop on
Got it thanks!
I have a VAIO laptop and i have this Black-screen issue. OMG Oh my god o_O :-)
what about if the screen is white with no image.?
thats a screen issue, test on a external screen via vga or hdmi port
Do you sell iptv
sir thank you for a very informative video. but i have a problem with my laptop. there is back light but know picture. i already check the cable connection to led.. still have 3.3 volt. but there is no image sir..
change the screen then
sir i already change the screen. i already have 3 screen sir but still no picture...
check with a external monitor
the +lcd_vcc have 3.3 volts sir?
its a led or lcd?
I have a motherboard that needs that fuse
U r looking roks not a old 😊
