[@ArunGupta-uj1cs]

Sorin , i really enjoy when you talk about all the different things like space and politics in your videos. Thank you so much for what you do. You are an inspiration to me. I am truly grateful for what i have learned from you.... Thank you again and god bless you and your family.

[@donalperera5253]

Mr. Sorin.. I'm from Sri lanka... Sometimes you may know that country... U r my teacher... And my inspiration to electronics... Thank you.. So much... 👍👍👍

[@witzprinz4766]

I am so happy that I found this channel 6 months ago. I was a complete noob when it came to motherboards and how electronics actually worked, I only knew how to build pcs but you have helped me so much Sorin. the people you helped will make the world a better place for everyone, I promise you that.

i am catching up watching all your videos, i gotta say i really enjoy seeing you struglin with TV screens like we mortals do. I check every led light individually by scratching the tracks between them, you should try it, way easier. also i am one of those "7 min watch time" guys because i forget wich videos i saw and wich not so i cut a lot of them after a few minutes, don't mind that statics. also on the demonetization on youtube, remember that you say "stupid fault" a lot, that can be picked up by the algorithm for censoring. keep it real, a lot of youtubers will edit the video if they found out they forgot to unplug the battery like you did in this video, i really apreciate this 'real time' thing you do, I am learning very useful stuff from you because of all the process of finding the fault instead of focusing only on the repair. thank you very much Sorin. greeting from Argentina.

[@K1ZEK]

I don't know what I like more, your thoughts about Life, Politics, or technology. We share the same values and thoughts on consumer electronics. Blessings to you and your family. Leo

[@zambattmovcon7827]

great teacher, was wondering about how a computer works, did a certificate in computer hardware engineering but i realized i did not have enough data to become a technician, i have since gone ahead to find more info, its amazing how computer works using gates 1s and 0s on/off of electric current to transfer data between the CPU and RAM using a Bus, this is why u said the only thing we can repair with laptops mostly is electrical faults and not data.....,,

[@ui30wf70]

such wonderful personality i like way you thinking :) i really enjoy watching your videos sir thank you for sharing with us.

[@ziggyironic]

Thankyou once again for taking the time to make these videos and for sharing your extensive knowledge.

[@ope501]

I have followed Your videos long time, so thank You for these. Was about to ask how brexit and this truck driver problem happened, but got an answer already with this video. 🤔 I like to learn, how to fix things, but also I like to hear about Romanian history and how is it going nowdays in other places, like in GB. I live in Finland and from my 50+ year experiment view, world has gone a little bit off odd. Nice to listen You, many things You say, makes sense. Maby I'm getting old and want that everything is not changing so rapidly.

very deep thinking sorin, i love it, humans are hell bent on recreating humans converting energy to mass or recreating ourselves atom by atom, maybe it has already been done millions of years ago and we are just repeating it.

super repair :) genius work Sorin :) also just to let you know I love watching the laptop repairs mostly :) but would like to watch the whole repair start to finish :) when laptop is back together and working )

Nice job Sorin! You saved another one from the landfill.

[@digihorse6730]

Sorin have you seen the Northbridge Fix “ box of ports” maybe the usb c is in there.

[@AaronStarkLinux]

I have the same laptop, a few models inferior than that one from 2009, I have to say, the design is a pain in the a** when you want to open it, and the speakers are just bad quality, mine has the membranes broken too. But still working, despite the bad quality and bad design, incredible.

Sorin with the "No shit Sherlock" line.🤣🤣🤣

[@will_doherty]

Another good example of your expertise and knowledge, but a couple of things I was a little unsure about: I know that copper traces on pcb's are thin, but given the width of the trace that you cut, I'm not sure that the wire that you replace that section with was big enough? There were two vias in the section of trace that you cut out (possibly another one in the burnt bit?), which obviously went somewhere, so I would have thought the post repair testing would have been very rigorous, and checked that sound, camera, microphone, card reader etc. etc. still worked... At least then you could have said to the customer, well, 99% of it works, but the microphone or whatever unfortunately doesn't.

[@neelbanerjee3086]

nice talk sorin

[@ralphj4012]

A while ago you said the most important thing in business is money and this is, of course, correct. Hence manufacturers don't want their products to last a long time (rubbish power connectors, cheap components etc) and want you to buy replacements (airpods, phones) regularly. Subscription for everything (music, TV, song matching, apps etc) ticks all the boxes (never-ending, recurring revenue). I read somewhere that Dell is moving to laptops as a service.

Thanks for the video but wondered why you didn’t just scrape off the burnt part of the track rather than isolate a whole section and take a chance that the via’s needed power?

Hello Sorin did you hear about the PoCv11 update on helium ? i wanted to buy a hotspot but the limit of the 3dbi antenna stopped because im from Greece 40 km from athens and i think i have no luck with a 3db antennna , what do you think ?

[@electronicsrepairschool]

That's the beauty of pocv11, you can use 20db+ antenna and stay legal

[@gchaos9]

@@electronicsrepairschool But even if you use an 20db+ antenna the transmission power will be scaled down , So what's the reason to use one ? sorry for asking so many questions but i just don't get it :(

I don't really care of my transmision power, most of the money are from witnessing the other hotspots

My Sony Z3 Compact phone had magnetic charging too. One of the first waterproof phones. It was also really small and easy to hold in the hand with screen-on-times of over 10 hours. The screen was LCD and really bright. At some point all smartphones became the same. There's literally no differences. 6"+, too big, strong and hot processor, edge to edge display, 4500mah battery, around 200g, glas on the backside, glued sandwich construction. Why buy one over the other? Companies are stupid.

Hi Sorin, I'm a big fan of your videos here. I want to ask your help please. I have a Toshiba Satellite L50-B-1J3 laptop, the LCD ribbon was broken, it is starting up correctly via HDMI. I replaced the ribbon but still not displaying on LCD. Apparently the VLED 19 volts disappeared from the pin 38-40. Do you have a schematic diagram of the motherboard or any suggestion where do I find the circuit which responsible for the LED backlight? Many thanks. Tamas

Where is your imagination Sorin? :-) 100% cpu usage, integrated gpu during game, battery charging and you thin wire will meltdown. You are lucky that this version of that model, doesn't have a dedicated gpu, because then it is 4.75A 90Wats.

Microsoft isn't considering. They are forced to. By initiatives like yours, rossmanns and many others. Rossmann is actually heavily lobbying on right to repair now. US govt is also mandating R2R by law now. And Europe is a bit behind but is also brewing something in that regard. So people and lawmakers are making it happen. Not manufacturers. They're just making it seem that way since they're losing that battle slowly but surely and now they want to make nice towards their customers, whom they've been robbing blind since their inception.

Apple are becoming very greedy and selfish . Who are they to dictate what you installed on the hardware you purchased from them .

You should have the right to do what you like and also the right to repair your own equipment that you purchase and pay full price from the charge enough for the bloody hardware and then they stop you installing software and repairing your own products that you pay for their a joke
