Most people don't take so much effort to go for the extra mile. Awesome job.
Well we do offer a 1 Year warranty on all of our mail-in repairs so that forces us to go the extra mile and make sure everything is done right! Also it just wouldn't feel right sending something out I wasn't sure I did everything I could to ensure it's 100%.
@@NicksTVRepair I wish there were more people like you man
I appreciate the kind words.
It also does come from a selfish place. I want to be succesfull, and in order to do that, I need people to spread the word about me and one way to get that to happen for free is by providing the best damn service you ever did see :)
Also sharing all my trade secrets I know for free on RUclips helps
@@NicksTVRepair I wish I started seeing your channel earlier because about 1 year ago I had one of my samsung PSUs fail I could have fixed it :)
Good job, although I would add some wire across the broken tracks to reinforce them. If not reinforced, the solder alone can break later from heat expansion and contraction, causing an intermittent connection. Ask me how I know !! Lol.
I save old pieces of solder wick to bridge broken traces, great repair!
The structural integrity of the board is lost in that area, I definitely would have bridged the broken traces.
I'm glad to see that you take pride in your work. After 42 years of repairs, I still treat my repairs as if they were my own.
That’s the mentality that works, and why chains fail
good details and soldering practices
Thanks 👍
I love watching people work on stuff when they really know what they are doing. Good job. I curious as to what microscope you are using.
Sorry I have no info on the microscope. We bought it several years ago and I have tried to get the info because we have gotten this question many times. When I went back to the website I bought it from it was discontinued so they took down the listing and I can't access the purchase history anymore.
@@NicksTVRepair Ok. Thanks so much.
Love all repair videos as i have always been a tinker and love to fix anything that's broken but your videos are made with such pride, 👍
Thanks 👍
Thank you for your long term fix philosophy.
My pleasure! :)
great job, well done, well explained, amazing camera focus, thanks for everything ❤
You are strong. 👍
Thanks :)
Thanks for the video, it is a veryinformative video. Iam just wondering why does the VS reads 221V. What components the tv needs 200 volt to power ?
I know that the Y-sustain board uses it but don't ask me why or how haha I don't really know the answer. I know how to fix it though!
What was the values of the diodes?
Thanks!
You bet! Thank you for the tip
god bless you , mashallah
Three questions. What tool is used to scrape up those traces. What connector tool was the shorting ps on to ground and do you have a donate link somewhere? You are very helpful and I'd like to send some $$
hello,
I thought I had sent you a reply but maybe not.
The tool we use to scrape up the traces is a fiberglass brush which I will link below:

The jumper wires I used are these:
amzn.to/3ZppFaF
And yes we do have a donate button on the bottom right of the video there will be a little icon with a heart and dollar sign inside the heart along with the word Thanks next to it. That is the donate button. :) Thank you
@@NicksTVRepair thx, sent a little something. Is there a method on what content you post? How do you decide what the next video is? I have issues with those Samsung 50/55 inch all in one boards that have some problem on the hot side.. not the mosfet either.. what are the chances something like this would show up in your future 😁
Awesome video,Nick. Have you seen my invitation of TM4K-AF digital microscope via email today ?
Hello,
Thank you for reaching out via the RUclips comment section. We get what feels like at least 1 email per day with partnership requests for microscopes specifically. Most emails feel copy pasted about how great my channel is and how it would be wonderful to partner up. I am pretty sure no one has watched our videos, you are the very first person to also leave a comment on our video in addition to the email thus confirming you have at least clicked on the video.
So I just want to say that by commenting you have stood above the rest by a mile. If I had to pick someone to partner up with it would be you.
With that said, the microscope you have I don't think would work well for us and our work space. The one we use I beleive is of much higher quality and doesn't have a screen integrated in it which yours does. That's a negative for me. I don't want a screen, I want to be able to plug an HDMI from the microscope to the 55" screen a few feet ahead of me wall mounted just behind where the camera sits when I do my videos. It makes it so the desk is a lot less bussy and I have a much larger screen I can look at. Also makes it easier to manipulate the device and move it out of the way.
Sorry
how to find which one diod volue I am India
❤❤
Great video and explanation! What flux and solder are you using?
Soldering Iron: amzn.to/3FQfyhG
Solder: amzn.to/3qScy0d
Desolder wick: amzn.to/33DAjjy
Flux: amzn.to/42YWYBa
@@NicksTVRepair Thank you so much!
Yup!
Apply more lead com out with out damage
Not sure I understand. Are you saying to add more solder when desoldering?
@@NicksTVRepair yes
I see. Yes that can help
Sir i want details of KD-55A8G 4 x blinking solution
That's backlight failure. Since your set is OLED that means you have a bad panel and need to buy a new TV. Have someone diagnose and make sure the power supply isin't bad before tossing it though, it's rare but can happen.
Grt work ❤
Thanks!
🎉❤ i am power supply fan boy
Haha great I do have a few more power supply repairs I will be doing in the next few weeks. Stay tuned.
Surprised you didn't correctly torque the devices to the heatsink. Critical step.
torque the devices to the heatsink?
What does that mean? Are you saying to use a powertool? While I am all in on power tools this is an aluminum heatsink. Very soft metal and easy to strip. Not sure that's a good idea. Trust me the screws are tightned perfectly well, we have done this several hundreds of times with no issues.
With the amount of repairs you do, is there a reason why you don't use a vacuum desoldering station? I know for me it has been a great convenience and game changer. Removes more solder in one shot while doing it faster thereby reducing the chance of pad/trace damage. Also, it would have been a good idea to reinforce the crack in the PC board substrate itself to prevent it from flexing, which can cause the soldered trace repairs to break again in the future. Speaking of which, adding pieces of wire or wire wick braid to join the cracks in the traces would make for a better long term repair. Not criticizing you, just suggesting.
The reason I don't use the desolering station on small jobs like this, is because they require maintenance, cleaning, if I keep it on the desk, it's bulky and takes space, I would rather have a clean workstation which then means it's put away so now I have to take it out, set it up, it takes a bit to get to temp, by the time it's ready to go if I have 6 joints I am desoldering I have wasted more time setting everything up than if I just go for it with the pump and iron.
It's not a better tool unless we are working on 15 or more joints. On big jobs with lots of desolering it makes sense to use it, on small jobs like this it's harder and more time consuming to use the desolder pump.
As for the cracks in the board you are correct we could reinforce it with a strong adhesive and we could also put wire in there which we used to do in the past. But the thing is that the board is going to get screwed into a stationary TV and locked in place with no movement. The only reason it got cracked in the first place was because of poor packaging during shipping. So it's unlikely to have a repeat crack unless we poorly package it when we ship it back. If it was going into a vehicle, an RC car, a drone, or something with lots of movement and prone to shocks then we would have reinforced it. But I don't think it's necessary here.
you should really invest in a heated solderpult. they work way better than what you were doing.
a heated solderpult?
Do you mean a desoldering gun or desolder station? We already have 2 from Hakko. They don't really make sense to use when desoldering such small amounts of components. When we have 15 or more joints ill take the time to take it out, set it up and use it. Otherwise it's to much work for such a small pay out.
Thank you for solid procedure. Dunkin /$TarBuc / TimHortons toast to you & your technicians.
Hey thank you so much! I really appreciate the tip!
So you tested all the fuses within the first minute (@ 0:56) and stated that they were all good/working, but then @ 9:26 you're "replacing the fuse again since it's blown"..... so which is it??
🤔🤔🤔🤔
Also, are you getting paid for these repairs, or is it simply done for educational value?? I only ask because it's a little bizarre that any repair technician would replace a bunch of components on a PCB "just in case they fail" one day!! If that's your approach,, why not just ship the customer a brand new board? It seems to me that ALL the components "could fail" someday, so why are you just randomly picking & choosing which ones to replace that aren't even broken/blown yet?! Are you only replacing them because you just so happen to have the same components in your shop?
What if you had to spend time/money on searching for/ordering replacements for components that are still in good working order.... would you still be replacing all those working components??
Unless you're charging customers on a "per component" basis, it seems like a great way to make ones business go under very quickly!!
Lol haha yeah I don't know. The fuse was good, I think that I am just not used to that because whenever the transistors blow that fuse is supposed to go out. But because it was tampered with the person probably sent it to us with the fuse already replaced and out of habit I just replaced it anyway because it's something I have to do every time with this repair. But you are right I did not need to replace the fuse here.
All boards we fix on the channel are not replaceable. You said why not just send a replacement, well they don't exist, it's either do a repair or you have to buy a whole new TV.
As for the repair, yes every repair we do here is from a customer paying us to fix their circuit board. We don't do this much work for free.
As for replacing randomly picked components, I don't think you understood what I was doing, and in all fairness, I didn't explain very well but in my defense, I can't otherwise we lose a lot of viewers who don't really care about those finer details.
All components I replaced need to be replaced to ensure a good repair. When the board fails, they don't always fail in the exact same way, there is some variance to it. So sometimes when it fails the parts that I replaced that weren't shorted are bad, however, sometimes there is no way to know because they don't fail in a way that is detectable with a multimeter but they are weakened from the stress of the transistors shorting. If left unreplaced they will actually fail within 30 minutes to 1h of the repair and the board will completely short out all over again. Also, there are certain components that after 10-12 years we see fail, so even though they haven't failed yet on this board, to ensure they don't fail in the next 6 months- 1 year or so, we preemptively replace them to ensure that once we finish our repairs, the board doesn't come back with a different failure we could have prevented. Think about it like this, you have a car with 4 tires that you drive for 50,000 miles. One blows because you have gone through its life cycle. You are telling me it's a waste to preemptively replace the other 3 because they are still good?
Trust me there is nothing random or wasteful here, we have fixed about 500 of these units in the last couple of years, and everything we do and show you here is very much necessary.
I am subscribed to your channel, but if you could provide a little more detail of all the parts you are replacing, that would be great!!!
What amp+ voltage on 3pin smd diode?

Hello Nick in your tutorial I have never seen a screen problem video, don't you encounter with screen problem or u just specialize in board?
We do encounter tons of screen faiures and while we are able to fix some, we aren't as good with repairing them as we are circuit boards. Often they also can't be fixed. We have tried doing repair videos on screen repair but it's kind of a nightmare to do a video for those. It's much easier to do board repairs on screen because we have fixed hundreds prior and know exactly how to properly and fully fix them.
We also preffer to fix boards than screens.
We may have more content on screen repair in the future, but I don't see that happening for at least a year or so.
Great video! Thanks!
You bet!
we still don't know what you replaced them with, not informative!
With proper replacements. If you look at the components, they have markings that tell you what they are. Google is your best friend here.
@@NicksTVRepair best answer lol
@don4techy haha yeah it was probably a bit more sassy than it needed to be but it's just frustrating to have spent around 4h or so making this video to then be told that the video is not informative. But in reality it is true, that's how I identify components. I look at it, I see the markings, I google it and figure it out from there.
Wow.
Hello..Salam alaikum.. really i enjoyed the nice video & way to detect & solve ... I brand for removing color cod ...
Thanks
Ali ..
Thank you
Thanks so much Nick, i enjoy watching your videos and look forward to more, i especially like the way you've proven that the board fully works, so if the customer blows it up again, it won't be your fault and the customer could have more problems with the TV but i like being positive and i hope the TV works perfectly...🙂
Yeah for these we almost never had any issues with installations gone wrong with customers, they are pretty straightforward. We do however get lots of calls saying our repairs didn't work with Sony mainboards because those are not plug-and-play and often require pairing which can be tricky and a lot of people have a hard time with that. Those require a ton of customer support for people to get it right. Partially why we charge more, not because it's that tough of a repair, but because we often have to spend 20 minutes on the phone with people explaining how to properly install it and make it work with their TV.
good vide and content. thank you. those right angle tweezer like tool you use for moving the pins, etc, where did you get those ? please let me know.
Those I bought off of shopjimmy.com
Good job
Thanks!
THANK YOU VERY MUCH FOR THE GOOD TUTORIAL SIR..
No problem!
Nick,
Thanks 🎉
No problem!
