I'll be checking my board today & I'll be sending it your way if that's my issue! Great video & thank you for sharing.
Heat trick doesn't always work. Try a few times, but if you still have issues, send me an email directly (contact info is in the video description) and I can help troubleshoot further.
Fantastic. I will send you my board!
Please do!
Thank you you and your tech engineer are great and to the point
You are very welcome
That is a great job that you did.
Thank you
You guys are good!
Thanks
Superb job
Thank you!
Great teamwork guys that solution was amazing to watch
Thank you!
I appreciate the video, and especially your video on the back cover removal. That helped immensely, I was afraid I was going to break it removing it.
I have the same exact TV, just died while watching. Prior to that I've had a couple times in the last year where the TV wouldn't power, I would unplug it from the wall, wait a couple minutes, plug it back in and it would work. I've also had issues sometimes where the colors on the screen are inverted, but after changing the picture resolution, then back again, the picture would go back to normal.
I've seen on forums some people say it's the power board, others say the main board. I tried the heat trick and it didn't work. No power, no light, no anything.
Is the mainboard replacement my best bet?
If you have this exact model TV then yes the mainboard is the most likely culprit. I have never seen this unit have a bad power supply before. If you saw someone have success with a power supply replacement on a forum it must have not been for the same model TV they must have been talking about another 4k Vizio LED set.
Heating doesn't always work, sometimes the cracks in the solder joints are just to far gone and heating won't be enough to temporarily bridge the gap again.
If you can't find a replacement, we do offer a flat rate mail in service to fix your original defective board which comes with a 1 Year warranty.
Heat
Does that heating the main processor work on other brands as part of troubleshooting?
Heating the processor as a troubleshooting step works on any device that suffers from cracked solder joint faults. If it doesn't work for your unit, it means that either your unit is not suffering from cracked solder joint on the CPU, or the cracks are so bad that heating it up won't be enough to temporarily fix it. This is why sometimes it takes 2 or 3 tries. I wouldn't do more thant that, otherwise you run the risk of overheating the processor and potentially damaging it.
What model TV are you trying to troubleshoot currently and what symptoms are you experiencing?
How does one get into learning this type of repair, diagnosis tools ect?
It started as a hobby 10 years ago, buying broken TV's on facebook and craigslist, and learning how to fix TVs from forums, youtube videos and so on.
For me it started as trial and error. After about 2 years I was confident enough in my ability to fix these to start repairing them for customers instead of just buying broken and selling refurbished.
Where can i get the right BGA stencil? is this a specialized stencil that i have to order somewhere or can i get a pack of assorted stencils and it will be included?
We typically talk to suppliers in china. You can use universal stencils, but they are a bit more difficult to use typically.
Usually we try to get some custom made for each chip if they are not already available.
Most of these we find from sellers in china. Aliexpress and alibaba have tools and components available for sale. Taobao is also a good resource for parts.
@@NicksTVRepair perfect thanks so much!
Where do I get good solder wick like that? I can only find smaller stuff and some of it doesn't even work. It doesn't fan out because its too small and the braid is too tight.
That's a good question.
Here is a list of the soldering equipment we use:
Soldering Iron: amzn.to/3FQfyhG
Solder: amzn.to/3qScy0d
Desolder wick: amzn.to/33DAjjy
Flux: amzn.to/42YWYBa
Hi good day, I have a Vizio d43f-j04 TV three months ago when I turn it on there are some white lines from the icons are the caption are any thing that light in the picture,, if I turn down the brightness are the contrast it go away a little,
I change the tcom board and all so the main board but no luck
If you already replaced your mainboard and the T-con board and still have issues with lines then it means most likely your screen has gone out and needs to be replaced. This is typically not financially viable and means it may be best to look into a replacement TV.
Do I need to use ceramic thermal paste or will regular thermal paste work too?
As long as it is a good quality thermal paste you can use it. We just happen to use the Ceramic one, but others work as well.
@@NicksTVRepair perfect thanks! I asked somewhere else too but I’m not sure if the comment posted, where can I get the right BGA stencil?
Is the temps you mentioned in C or F
Celsius
I have a m50 C1 it shows a stdby light, light goes bright with power on, and occasionally shows one half good and the other side distorted, most time it does nothing, no BLs, no pic no sound. I noticed the V logo showed good on both sides the one time it actually came on. Reflow? let me check the PS on signal...PS-On come up to 3.7, but on-off does not.
Yup you are going to want to do a reflow on that one. I do recommend reflowing both the main processor and the video processor. Both suffer from cracked joints and issues so if you are going to reflow one, might as well reflow the other as well.
We always do both to ensure the board doesn't fail again soon because if you don't there is a good chance it will come back for repair within a year. If one went out, the other is not to far behind usually.
My Vizio is a couple of years old and recently on Father's Day :(. The tv turns on and you can see the screen come on, but it's a black screen. I've tried all of the easy fixes, but nothing works. Tech support mentioned a possible power supply issue? They're sending me a refund for the TV. I'd hate to toss the TV and would like to fix it myself. Any suggestions?
Please reach out to us via email or fill out the contact form linked in the video description.
Please include the model number of the TV, and provide as many details as possible regarding symptoms. I can assist further from there.
Hi the same thing happens to my smart 55inch vizio tv.now I'm stuck with out it.😢
Hey Nick, got Vizio with no pic no sound but power light comes on then nothing. You got a guess which board it is? I’m guessing the main board.
Without knowing what model TV you have, I can't really help you. Vizio has made hundreds of different model sets all with different types of failures. Please provide more details
Sorry the D70-F3
Power light comes on, then screen changes tint lie it’s coming on then nothing. Still nothing when using a flashlight
Hey guys ! Do you k ow the thickness of that thermal pad ?
If you are referring to the pad on the back side of the board, I don't believe we typically replace that one as it usually is in good condition and can be reused.
I wish I had my old TV that did this still
next time!
The bga reballing looks easy..is it really Easy or any other complexities are involved??
Reballing is not an easy task, it may look easy in the video but that is mostly because the tech in the video has done it thousands of times. You were shown the entirety of the process in the video, there are no other hidden parts or tricks to it.
How do you fix when it turns on then eventually just shows picture but no sound
The symptom is slightly different but the cause of the fault is the same, cracked solder joints on the processor. This means the repair is the same as shown in the video. Different symptoms can manifest from this issue but the repair doesn't change.
I notice everyone wears gloves is that to prevent exposure to lead ?
The gloves are more so to avoid getting flux, or thermal past on my fingers.
You may know more than I do, and if someone does and wants to chime in, please do. But my understanding when it comes to the leaded solder is as long as you wash your hands after using it, as long as you have a good fume extractor then you should be okay.
@@NicksTVRepair yes that thermal paste and flux is very sticky. I used to work in a tv repair shop years ago. You're work skills are excellent especially when it comes to soldering.
they need to make the chips like CPUs so you replace them easy.
If they did that, then they wouldn't need to get fixed as often either. You wouldn't be getting the cracked solder joints that we so commonly see on so many devices.
Only issue is that the chip might have to be much larger to allow for more pins and connections between the board and the chip.
Nick can I mail you my board for this repair??? :)
Hello Matthew,

All of our contact info is in the video description including a link to the repair service page for that board. If you have any questions feel free to go to our website contact us page and fill out the form or contact us directly via email.
Again the contact info and repair pages are linked in the video description above.
Now I am not saying this work for everyone but my 9 year old Vizio tv lost the picture I tap it whit the palm of my hand and the picture came back I was not ready to buy another tv 😊
This will not work for 99% of cases. However this means that you have some sort of loose connection somewhere causing your fault. This might be a big clue as to figuring out what the issue is. This could be a loose connection on one of the ribbons or wires, or it could be a loose connection between a component and a circuit board as well.
@@NicksTVRepair. I’d say that works as many times as “A HEAT GUN FOR 10 seconds on a board “ with the metal cover ,thermal pad & the Paste “ 💁♂️.
They are 20 vids telling people “THESE 5 STEPS WILL ALMOST ALWAYS FIX YOUR TV”.
Unplugging it ,🙄 & 10 more mins to waste people’s time with a vid label. Lol
Those vids NEVER FIXED A DAMN TV.
Not 1
😂
All the more reason not to buy this tv due to chip needing re soldering, if buyers vote with their wallet they will have to manufacture more reliable chips with pins.
Unfortunately this is something that every manufacturer accross many industries do. From what I have found, there are no good choices, because everyone votes for cheap
so in other words go buy a new tv because you don't have 10 grand for that machine...maybe i'll take a chance with the old xbox 360 red ring of death fix
This is why you would hire us to do the job for you. We offer a flat rate service which is very affordable and much cheaper than purcahing a new TV. Plus we do a 1 Year Warranty on all our repairs!
This video is to show you a behind the scenes process of what we have to do to fix these boards, and that we have the ability to fix almost anything on these boards! We do the job right and stand behind our work! Links to the website in the video description.
What about M65-E0?
No standby light no power?
Thank you for any response🙏🏽
Yeah this repair also works for that model. If you open up the TV you should find that it has a very similar mainboard.
