A huge Thank You for this repair video! I bought my 70" Vizio in 2016 and even paid $100 for an extended warranty to give the TV 5 years... but of course it's now 6 years and out of coverage. I started having issues powering on the TV a few weeks ago and was pretty sure something was going in the power supply and wouldn't you know it... today it died for good. :( I tried everything but couldn't get any power light activity. Seeing as it was basically E waste, I found this video and thought I'm going to give it a go. I'm not an expert with the soldering iron, but your instructions on removing the bad caps and cleaning up the old solder worked like a charm. I was easily able to pull the caps. Then I went to my local supply store and bought a bag of capacitors for .40 cents each (1000 uf @ 16v), swapped them in and the TV fired up like a champ. All told it took me about 2 hours to fix (I went slow and careful) and it only cost my $1.60 in caps. Thanks so much for this video - it saved me from having to buy a new TV!

Extreme gratitude for making this video. It allowed my to fix my Vizio M60-C3 (same model, only 60" vs 70") and get it up and running again in a day. In hopes of helping someone else identify the issue sooner. It started several weeks back where instead of the white light coming on and then a few seconds later the screen would come on and the Vizio logo, it started to happen that I would need to cycle the power off again with the remote, then back on for the picture to come up. A few days later that process needed to be repeated 2x, then later 3x, then later 4x, and eventually it would take about 10 mins of powering off and on before the picture actually came up. Right before the TV completely failed to turn on I left it on for an entire day to avoid the cycling, that next morning the TV just randomly turned its picture off (sound was still going) and it never came back on. I tried to cycle power as before, but this time the white led in the left corner would never even come on, it was completely done. Overnighted a 20 pack of 1000uf 16V caps and some solder wire from amazon prime, disassembled the TV, took off the power supply board, cut off the old caps, replaced with the new and soldered them on. I replaced all 7 of the 1000uf 16V in the upper right corner of the board, even though only 4 of them, the ones in the video, were visibly bulged. For $20 in parts and maybe 1-2 hours total in time its back up and running. Thanks for the video mate.

That I know of for this model the LED strips aka backlight when they go out, I don't believe will damage the power supply. However if they don't get replaced you will start getting dark spots on the screen, which obviously will degrade the picture quality. There are strips available online you can purchase to replace but that is a much more intense/labor intensive/delicate repair.

Vernon, That's a gold mine right there. Once you do a dozen or so, HDMI port repairs are super easy. It's not an identical model but we have a video on repairing an almost identical board: studio.kzbin.infoYt5I267k5fw/edit This one was one of our very first vidoes we did a year and a half ago so its not as concise and it kind of goes on for a bit but we show you exactly how to fix it. As for the HDMI port comment I had an LG TV come in with every HDMI port knocked off. I think you may have commented on that video before, it was this one: kzbin.info/www/bejne/kGaXgGl9bdqogKc $50 per port is kind of expensive and also kind of cheap depending on the device. If it's an Xbox or playstation, $50 is kind of low. Those are much more difficult to replace and take way more time. Most often you are also expected to completely dissasemble the device and put it back together which takes time. For a TV circuit board $50 seems pricey. We typically charge $25 unless there is trace damage, then we charge closer to $80 or more depending on how many traces need to be fixed.

" im not planning on putting $$$ into it. What do you recommend?" Then I would recommend you toss it out. You can't fix the TV for free.

This is great. Thanks for the in depth video. I have an M70-D3 that recently died this way. I don't see any capacitors bulging. Is there a way to voltage test this power board or individual capacitors before moving scrutiny over to the main board? If I can fix the power board I would keep the TV. If I have to pay $100 to fix the main board I am binning this TV. It's possible my Roku or PS5 fried the main board over HDMI. There were no storms here.
@NicksTVRepair Жыл бұрын
The M70-D3 has a power supply built differently and does not suffer from the same faults as the power supply. If you have a dead no power issue for that model TV I would expect it to be due to the mainboard. Yes, there are voltages that you can check on the right connector. The connector will have a legend telling you what voltages are expected out of which pin. This power supply does have some voltages auto turn on, while others wait for a command from the mainboard. Check the standby voltage, your AC detect, and your 12v lines. If you get those, then your power supply is most likely good and the mainboard is the fault. Now to talk about whether it is worth repairing. Well, financially it would make sense to get the set fixed even if it cost $900. Why $900, that is the cost of a similar quality TV right now. Yes, you can probably find a lower quality 70" for $600 on a special promotion, or sale, if you are patient, but those deals aren't always around, and it's usually the low-quality sets. As long as the warranty of the repair is the same as purchasing a new one, I don't see a downside. The TV is built very well and doesn't have tons of different parts failing on it. The only part that does fail is the mainboard. So once that part is serviced, this TV is worry-free, there is an extremely low chance of say the power supply going out, or the backlight going out in the future. Newer TV sets are built cheaper and cheaper and fail much sooner than older sets. Anyways I could go on with that, but we do service the mainboard for your model TV, we charge $129 and offer a 1 Year warranty on the repair. In my obviously bias opinion, that's a killer deal no one should pass up on.

@NicksTVRepair Жыл бұрын
Kyle, I have also come accross this in the past. In fact customers are usually aware of this prior to the repairs, and for this model I have started telling them ahead of the repair that all we are quoting them for is the repair of the power supply, and nothing else. If there are additional issues found after the repair of the power supply, additional fees will apply. You can't work for free, if you fix the power supply you have to get paid for it. Sometimes when I put my LED tester to the strips they appear 100% and I can't detect a fault because they all light up. And yet they are dim after the repair. I have also had situations where the customer gave me an okay on the repair of the LED strips, so we did and post repair the exact same LED's were still dim. We then swapped out the LED driver board, and still some of the strips in the same spots were dim. We know the wiring is good because we can get them to light up with the LED tester. A bit of a mistery.

@NicksTVRepair2 жыл бұрын
Bill, You said "I replaced 3 all the caps you recommended" is that a typo? What do you mean you replaced 3 caps but also all of them? Make sure to replace all of them because if you don't you could have more issues soon after. As for the dark screen post repair, it's likely due to an led failure. One of two things could have happened. Either the LED's just happened to fail around the same time your power supply did, or moving the TV around from vertical to horizontal or moving it from one room to another caused a strip to shift or move slights and could have disconnected on of your LED strips causing a second of the screen to go dark. If I were you I would open up the TV down to the LED's disconnect and reconnect each LED strip and reboot the set (without putting the screen back on) If this solves the issue then you are good to put the screen back on, if not, then you will need to replace the LED strips.

I have a Hisense power board, the main cap is bad, it puked the junk all out, but next to it is a space but there is no cap, the pads are in parallel so if I added another cap it would double the capacitance, so why is there a blank space with no cap?
@NicksTVRepair Жыл бұрын
The blank space is there because it would cost more money if they made a version of the board without the blank space. A different version of the exact same board is used for a different version of the TV perhaps a larger model that requires it. The manufacturer didn't want to redesign an entirely new power supply for each TV they made, so they designed 1 power supply that fits 5 models let's say. Then they just fill the components into the board based on which TV the power supply will go into so it works properly for it. This way you only have to design 1 board, the manufacturing company doesn't have to rebuild the factory to adjust for different types of boards, and it saves time and money. This is why people say don't purchase the based on the board number aka number printed on the board because that number fits with different model TVs and not all are compatible but instead go with the part number which is the number printed on the sticker of the circuit board.

Before I replaced the capacitors, the board was making a relatively quiet high frequency noise that played on two second intervals, lasting one second. After replacing the capacitors, the noise has changed to a buzzing static electric noise that plays constantly. Curious. It only makes the sound when the tv is plugged in but powered off. (Pressing the “power on” button causes it to go silent) I suspect that it’s the tv’s standby power systems that are causing the capacitors to fail. But I’ve got just one day of electronics experience on account of the soldering I did, so take that with a grain of salt.

A retired neighbor of mine had us bring his tv out to the road for trash collection after it stopped working, and I asked him if I could have it instead. I figured that it would be cool to see what the inside of a tv looked like, and maybe I would be able to see any obviously failed parts and repair it. Realized a little too late that it was a catch 22. If it happened to be an easy fix, I’d be pretty much obligated to return it, and if it’s a hard fix, then I’d be unable to fix it, and I’d be left with a 40 pound paperweight after my curiosity died down. Turned out to be an easy fix, so I’ll return it soon, but I’d like to diagnose the buzzing sound first. Kinda drives me crazy imagining him throwing out the tv again if the capacitors fail when it’s just a half hour fix.

Can you still hear it when the TV is closed up? If no then I would say it's probably fine. If yes, then I do not know as I have never encountered that before.

Yeah but we charge vey little for our work, and it won't affect functionality but adds extra time to the job. When you have hundreds of boards coming in, unless the step is a necessary step to ensure proper functionality, we won't do it.

I assume you watched the video and checked to see if you have bulging capacitors correct? If you do, then your power supply of course needs new caps. If not then most likely it's a mainboard. I have not yet seen anything else other than the caps go out on this board before, so I wouldn't recommend replacing MOSFETs unless you are finding shorts on them.

Great detailed Video Nick. Thank you. Do you know if the power supply on the Vizio M70-C3 can handle 240V ?
@NicksTVRepair Жыл бұрын
That is a great question to which I do not know the answer since I don't have one in front of me right now. However an easy way to check is to look at the sticker right next to the power plug as it should tell you what input it will allow.

@@NicksTVRepair Thank you Nick for taking the time to reply. The sticker says 110 and 60Hz, I have successfully used my samsung TVs on 240v despite them saying 110 only. I think I will open the back to see if there are any markings on the PSU board. I have heard this sometimes carrys the marking of 110-240v. If not I will just have to continue to use an external transformer. Cheers.

Do you or anyone know anything about the Kent Liew books I see around the net, seems hard to get any info on them. Are they any good? They appear to have a lot of info in them.
@NicksTVRepair Жыл бұрын
I am not familiar with them. I have purchased in the past books similar that talked about common faults with certain model TVs and how to fix them, but they ended up not being common faults, most of the issues seem to be one of scenarios, they never really talked about how to diagnose and they didn't have a digital version so it was always very hard to look up information.

Is it really worth it to replace the LED/LCD screen say, a 50", screen on a smart/ 4K? Have a Vizio 50", unit works but the screen is messed up. Thank you 🤓
@NicksTVRepair Жыл бұрын
The screen is never financially worth replacing on any TV screen no matter what. The screen is messed up in the way that it is not producing picture correctly due to internal failure, that can be fixed, however if you say it's messed up in the sense you kicked the screen or threw a remote at it, then it is physical damage and can't be fixed economically.

@@NicksTVRepair yeah, I thought so. The Vizio I believe has several cracks in the screen, so even tho the TV is trying to produce a good image, the screen is damaged too much. Thank you for the reply & great video! Also have an LG 43" 4K, but think it has a backlight problem!

Great video! Just a quick question. At the beginning of the video you mentioned this particular customer said there was no power surge of any kind so that the problem likely stems from the power supply. I have a Vizio TV that will not turn on due to a power surge. Will this be a main board issue most likely? I did attempt to replace the entire power supply, but no dice.
@NicksTVRepair Жыл бұрын
That is correct a power surge almost always affects the mainboard and almost never the power supply. That is because the surges come in through the data lines such as ethernet cable, or HDMI. Somtimes it comes in through your antenna or other such cables. If you aren't sure what needs to be fixed we do service both the mainboard and the power supply. If you would like to send them in, we can diagnose them and repair which ever is at fault. It is however most likely that the mainboard is your faulty board and will need to be repaired.

I have a Vizio D32x-d1 that has no 5v rail out of the power board. All the 12v lines are good, and when I turn on the tv, the power light comes on and dims out as it is supposed to do, and I have 3v on the on-off terminal at the power board then. Ground terminals all show continuity to chassis ground. But it never shows 5v at the 5v terminal. All components look fine on the power board, nothing burned or cracked, and no bulged capacitors. Any thoughts?

I'm on the second set of capacitors. Lasted 1 year. Why do they keep failing? There is something else on the pcb board that is causing them to fail. Does anyone know?
@NicksTVRepair Жыл бұрын
I don't know for sure, this is speculation, but I believe the way the PCB is designed puts a bit more strain on those than there should be, however, I also think the issue is due to the quality of the capacitors. We have kits available for sale, those are the same caps we use for our repairs. I have yet to see one of these come back for repairs a second time and we have been doing these repairs for several years. For a link to the repair kit, check the description.

I am currently out of stock for the capacitors, but I should have more available in a week or two. If you want to just buy them yourself, you can probably find some at your local electronics parts store they are 1000uf 16v Electrolytic capacitors. Please keep in mind those are the readings on the capacitors on my board, there are 2 versions of this board, and yours might be different so just check what the capacitors say on your board before replacing them.
