[@okejee3455]

Thank you for sharing your experience with us. I had to go back and rewatch your "About the motherboards, part 2" video (38min) to understand better how the startup chip controls the screen. Great video.

[@Infiniti25]

The video Okejee is referring to is kzbin.info/www/bejne/m3mkqqalrN1ppdk

[@vlatkosurlan545]

That's exactly the video that explains why he shorted the resistors.

[@arsenico78]

I had thought about this solution studing your past videos while i'm watching this one. I'm happy because this is a proof that i'm learning. Thank you sir.

[@risaict6816]

i Really Love you sir. every time i flowing your videos . and you are my best Teacher on youtube .

[@clarkkent2650]

This is exactly what happened to my laptop. Great Vid

[@Dr.muthanna]

Nice job we learn a new information Thank you Soren

[@donald1056]

Your getting pretty good at this

[@tristanboyle4450]

just wondering if you don't have an oscilloscope and you are trying to find the high rate of voltage change somwhere.. could you test the terminals of the components with an led and a high resistor?

[@tristanboyle4450]

also how did you know to short the two components to find the fault?

[@DumahBrazorf]

Could it be a driver or windows issue? It could be checked booting with some live cd distro.

[@djmdka]

Multumim, Sorin!

[@amtpdb1]

I have a small screen that has a driver curcuit that I think is bad. it has a 6pin driver chip marked 07AA with a R offset lower. This is on a 3D printer Malyan M200. Could you suggest how to find this chip as I have looked everywhere I can think of. What would you do or use to replace it with? Thanks for the videos.

[@trxraptor4106]

What did you do melt the resister with each other?

[@padraigocuinn8384]

Hi Sorin, i was just wondering what way you tackle multi layer boards

[@computersrepaircotesaint-l7407]

Great video thanks Sorin

[@PatrickRibbsaeter]

great video sorin

[@donald1056]

Another amazing fix

[@MrRvdbeek]

Now what did you do bypass 3.3v to 3.3v? Can you change the bright on de screen? nice repair magic one

[@rashh77]

An other nice job. Thanks a lot. Why did you not uploading videos as before? I hope there are not problems with your boss.

[@arielgarcia4199]

why not just replace the component instead of placing a jumper sir? just curious..

[@yuanho2883]

Great video, thanks for sharing!

[@joshcruz1122]

My dell latitude does the same thing where it flickers and it drives me crazy

[@swared1981]

i need your help sir i have the same model of laptop i tried to instal windows on it but in vain i use several version from windows 7 to windows 10 but i i always got a blue screen i tried changin ram module; also the hard drive i tried to install windows via 2 ways: from cd drive and from usb drive but the same thing i do an update to the bios but no results do you have any idea what can be the problem . thanks

[@juliusvalentinas]

you should have done a proper fix, back light not adjustable will cause eye strain.

[@thetiredtechie2704]

Weird and interesting case! :D Well done!

Sir it is amps current issue on vin volts by battery, when adapter connect got full current, pls reply if am wrong

[@topfan1402]

good day sir

[@allelectronicsrepairs7165]

I usually admire Sorin's methods and highly regard him as a technician, this time however, I gave him a "dislike". Why? Because he just put a band-aid on a broken leg. Obviously something was causing this fault and after his "fix", this fault wasn't removed - just swept under the carpet. Yes, the computer is (somewhat) working, as he admitted, probably without a full functionality of the NEW screen, and yes, I do understand his time constrains and cost of the repair to the shop. Was it effective? In the short run, yes. Was it professional? Hell NO! I, as a customer, would be furious if my NEW screen, for which I paid (most likely) wasn't fully operational. And, as this is (i think) a warranty job, the client has already some bad experience with the shop (she/he had to come back = waste her/his time x 2). If they discover lack of brightness regulation ability (granted, may not happen for a long time) and (say) take it somewhere else, this "fix"is going to be discovered... How it would affect Sorin's shop reputation is an open question. Bad reputation travels very quickly...

[@electronicsrepairschool]

You are the customer .... i will give you two option .... a repair like in video for £40 (but you can;t adjust the brightness) or a super io chip replacement (most like faulty in this case) for £100 ..... your choice? 100% of the customers go for the cheap one. I always said on my videos, this is a real life shop, nothing fake, nothing done only for a good looking youtube video.

[@allelectronicsrepairs7165]

@@electronicsrepairschool Sorin, if the customer WAS presented with these options and HIS choice was to go cheap, then YES, it was a way to go. What I was referring to was the situation which unfortunately happens in many, many service shops, mechanical garages, etc. When a customer comes with the engine warning control light on the dashboard, they give him the cheap and expensive options. The cheap is to disconnect the control light (so it doesn't bother the Client) instead of fixing the engine. If The customer doesn't know anything about cars, they may choose the cheap way, just because they will pay less (in the short term), not realizing that they may be forced to pay much, much more in the future for the engine replacement.

[@jonydarksy2600]

awesome job!

[@fereydoonershadi]

[@kimspeller6941]

[@zx8401ztv]

Sorin, i hope you are not getting into trouble with your employer because you are making videos :-(. Please stop making videos if its making your job horrible.

[@Infiniti25]

I'm pretty sure he is the boss since everyone comes to him in the other videos and he tells them the price to charge.

[@danielbayugar4856]

Good morning sir
