Watch the story of how I got a 65” 4K tv that won’t turn on (Vizio M65-C1) and my journey to fix it. The previous owner told me that it stopped working one day and would no longer power on. The LCD was not damaged so I definitely wanted to fix this tv. The information I found online about the M65-C1 ended up being extremely helpful for this repair. If you have this same model and problem I hope this video will help you to fix your TV.

I like to fix things. Do you? If so, let me know what has been one of your favorite repairs?

[@davidwright640]

Found a nice 50" SONY table top projection TV sitting on the curb. Sure it's a little older and bulky (fat) but still a good TV. Replaced the bulb for $25. With a cheap broadcast antenna it is now my high definition garage TV

I fixed my $1000 55 in Samsung TV for $30. When the picture when black I did what you did and search the internet. I found that the LED bulbs were failing. I found a video that gave step by step on how to take apart and replace. I found the LED strips on ebay. $30 for all shipped. I took the tv apart on my dining room table and replaced all the LEDs and it worked. My wife couldn't believe that I fixed it and basically saved us $1000 for a new TV.

[@Noah-or5gr]

was it cuz it was a bose sound system?

[@uski]

In general, when a fuse is burnt, there is another failure. Changing the fuse will not repair the unit. If the unit has a switching power supply, the most common fault which can blow a fuse is one of the transistors going bad and shorting.

[@kimmy080]

I just stumbled on your channel because I was having problems with my 4k tv. I like to tinker and didn't want to shell out the money for another one.

[@charleswilson4598]

I have a Maytag washer that quit working. Made a really loud screeching noise during spin. I looked it up on youtube and got some ideas. I started taking some parts off to look for the bad part when I noticed a nut that should have held these parts to the main shaft was missing. Bought a new nut at the hardware store for 13 cents. But my daughter found the old nut laying on the floor under the washer, so I wasted 13 cents. Re installed the old nut and fixed the washer. Dryer went bad just before the washer quit. Again, checked you tube. Replaced a tensioner bearing for $15 off eBay, dryer works fine. Grand daughters dryer quit after about two years of use. Cleaned the too long exhaust tube (cheap plastic), replaced $60 of thermostats and sensors and fixed the dryer and I know nothing about any of these appliances. Oh, last year fixed my furnace. Replaced a capacitor on my blower motor. And I am getting older and I am not nearly as energetic as I used to be. I admire your creativity but I was wondering what would you have done if you had not found a hint on you tube and had to start from scratch to trouble shoot your problem.

[@FrugalRepair]

Charlie Wilson Great repair stories! What would I have done if there was no info online? I would have quickly known the power supply was a problem due to that fluctuation. I would then visually inspect it, maybe I might have seen the hole in the resistor, maybe not. Then I would test components (like this diode), power supply unplugged, of course. The info online helped speed up the process tremendously.

[@charleswilson4598]

@@FrugalRepair I was watching your tv video because my 4-5 year old Vizio was turning itself off and on about every minute or so. Since I have found a lot of good information on you tube about repairs, I thought I would give it a try. I remember tv from the old days when they still had CRT's and high voltage power supplies and you had to have an understanding of how that stuff worked. Fast forward to 2019. Now we have LCD/LED screens and no high voltage power supplies and how things have changed. After watching your video and a couple of others I learned that these tv's look pretty simple even if you don't understand how the circuits work. There are a few circuit boards that have some wires plugged into them. It seems to me that a person could try to narrow down which board is bad and just replace it or if all else fails and the boards are cheap enough, just shotgun it and replace all the boards. Boards may not fix all the problems but chances are it would fix most. However, as a former electronics tech (now retired), I found your troubleshooting and repair very interesting.

[@RobGreco71]

Great video. I had a 55" Vizio that stopped working after 3 years. After some googling around and reading about similar problems other people had with this Vizio model I bought replacement boards on eBay for around $80 (it was a kit w/power board and main control board and other parts -- basically all the guts of the TV). Replaced them with my son's help in 30 minutes and the TV has been working great for past 2 years. Not quite a $0.47 repair, but a lot better than tossing the TV and having to buy a new one!

[@FrugalRepair]

Great story! So glad you took the opportunity to fix your tv.

[@Tronicsfix]

[@FrugalRepair]

Thanks! I was pumped to see your comment! I've been watching your videos since I found your channel this past summer. You do great work. The repair challenge with those other guys was fun and a great idea.

[@SaurabhSharma2804]

So you googled the problem "AFTER" you bought the TV? And there was just one person with the same problem on one forum?

[@FrugalRepair]

Basically, yes. I think I did a quick search to see if there was an common issues with lcd panel failures (which you can't fix) and nothing came up. Without seeing any comments about lcd panel failure I went ahead with the purchase. I've fixed many tv's so I was fairly confident that in the worst case, I would need to replace a board. And yes, after I got home and researched it more I found one post which saved a lot of time.

[@f.k.burnham8491]

If you leave the leads full length, the diode will dissipate more heat. If you shorten the leads, you must derate the diode's ratings. Quite possibly the diode overheated and failed. This info was directly from the engineering staff at Sylvania/ECG. My co-worker was working on am amp and the diodes kept failing. He went through 3 sets of new ECGdiodes and the same problem. Voltage and current were within tolerances. He called ECG and they told him about the lead length. (Back then the leads were silver) The lead length is part of the heat dissipation for the diode to run at full rating. Leaving the leads full length solved the problem. After I found out this info, I have always used full length leads with ZERO DIODE FAILURES in the 40+ years since. If you ever worked on older Japanese made TV sets you will have run across the power supply diodes having a loop in the leads. This is why.

[@FrugalRepair]

Wow, this is very interesting. Thanks for posting. I have been wondering why this diode failed and then apparently took out the resistor. My guess was either heat or a bad batch of diodes but I didn't do any experiments. I hadn't considered that the lead length would be that important to heat dissipation and second guess the engineer(s) who designed the board/circuit. Now, I'm curious to do some more investigating on this power supply. Thanks again!

[@TheKb117]

so, if you attach metal heatsinks to the diode leads sticking out at the back it would run less hotter and prolong its life. Assuming enough clearance when board is mounted. Also use thermal paste for better heat transfer. Just a thought.

[@guruoo]

​@@FrugalRepair This is why, 40 or so years ago, my HS electronics teacher drilled into me the importance of always looking for replacement parts that exceed OEM ratings.

[@TheKb117]

@Sam Polk though, iirc, some ceramic power resistors are sometimes mounted not flushed on the board on a horizontal orientation. Maybe for better heat dissapation while also not affecting adjacent components. Saw this on some old CRT TVs' power supply section.

[@FrugalRepair]

@Sam Polk Thanks for your comment. So are you saying that you think the failure of the diode is due to a manufacturing defect as opposed to a poor pcb/circuit design?

[@MirchiBoy]

Hi Tampa Tec. I have a Vizio M60-C3 coming into my shop tomorrow for a backlight job. Do you recall if the M-series has those damn internal clips that make removing the back cover near impossible to remove without destroying the TV?I had an E60 on the bench here last year and it took nearly 3 hours to get the back cover off,and my hands and arms were just BLOOD.I finally just went for it and RIPPED it off.Somehow I didnt destroy the TV set. If this M60 is the same design,Im turning the job down.Thanks!

[@redneckgearheadgarage495]

I grew up dirt poor. My brothers and I picked up walnuts and sold them to buy an old 1978 ke100 dirt bike. We pushed it more than we rode it. One day I asked my stepdad about it. He said "figure out how it works and find out why it's not." I expressed concern that I didn't know how and didn't want to break it further. His response has stuck with me for 30 years. "It's already broke, you can either figure out how it works or make it unfixable, either way you have little to lose." I now fix things for a living (manufacturing maintenance) I also have a really nice cook stove, dish washer that I got for next to nothing and have repaired for pennies, now I am working on a 4k tv for my sons room.

A couple of years ago, your videos inspired me to try fixing an old powered subwoofer that I got at a thrift store for $10 rather than simply returning it - I ended up learning how to diagnose the power supply board and found the main filter caps on the output of the power supply were shot. Got new ones in and it's been working great ever since! So glad to see that you're uploading videos again.

[@FrugalRepair]

I'm so happy to hear! That is a great story and I hope I can inspire even more people to try tackling a repair they might be intimidated to try. Yes, I am back to putting out videos.

I bought a brand new acer monitor from amazon. I had to travel to middle east for work. When I was there I had to change the power cables because they don't fit in middle eastern sockets. After two day the power cable melted inside my monitor and broke down the three pin connecter and the monitor shut off completely. I bought the monitor for about 700$ dollars and I was sad to see it break down that quickly. I thought about using the warranty on it but it would take so much time to ship a broken monitor to U.S have it fix and brought back to the middle east plus I didn't think they would accept it because the reason it broken down was because of a faulty power cable that I bought where I lived. I decide to take the monitor apart with no prior experience on how to fix them but basic electronics knowledge. I got to the power board of the monitor and it seems like everything was working fine except for the 3 pin connect input that melt down. I ordered a replacement for it for 0.35 cents. I desolder the old one and put the new one back in and that easily everything worked and I saved myself upwards 600$ trying to buy a new one. It felt great when it turned on and it got me interested in repairing electronics.

You can flood solder over the resistor and pick it up with your tweezers, or you can snip the resister in half and pick it up one half at a time.

Maybe you could help me Jesse Warren...I have a 75 inch LG 4k it's not even a year old yet and has horizontal lines at the bottom of it....everything g else works fine on it.....I reset it back to factory settings lines go away and then over time lines come back? Any suggestions on how to fix it?

[@garester94501]

Thanks for always making videos that are simple, concise and thoroughly informative at the same time. I'm electronically-inclined, but this is a whole new level. Your videos give me the courage to delve deeper into electronics repair. I've repaired several tv's, most with pretty minor issues. My favorite was a $4,000 marine radar/depth/speed/chartplotter MFD (multi-function display) I found labeled as "broken". It was a pretty simple repair. Now I have a super fancy MFD for my boat which I would NEVER be able to afford.

Trying to flatten out the resistor after one side has already been soldered down could just result in a stress fracture in the resistor.

Many years ago I fixed a $500 BenQ LCD with $20 of parts off eBay. The fault was so common that people packaged up the components with instructions on how to fix the power supply. My biggest repair was fixing an Aurora 5000 solar inverter that developed an E031 error. This is a very common fault on pre 2014 models. Replacing two $3 relays did the trick and the $2000 bit of gear is back in service.

One of my favorite electronic repairs videos that I've ever seen! I just bought this Vizio TV M65-in 4K quantum TV just like you.

I've been repairing things for years - but one of my favourite repairs was one a few months ago - in laws had a HDTV DVR which hadn't worked properly for years (we had been living in another country for some of that time) and FIL asked me to have a look at it because they wanted to use it again - it would power up, but not see the internal hard drive (but the hard drive would spin up). I opened it up and inspected the PSU - saw two swollen caps, replaced them, and it worked again! I felt like a magician.

I tried to repair my parents' 50 inch LG TV that broke down. The ESR meter helped identify a couple of caps that were bad, replaced them and a couple of resistors still no-go. I wanted to check the voltages but my dad didn't let me test with the board plugged in lol. If the problem is in the power transformers, or IC chips, I have no idea how to diagnose those things :(

[@FrugalRepair]

Thanks for commenting! Testing the output voltages on the power supply is one of the first things to check. You want to make sure you know what board contains the problem. I'm sure you can search online how to test the mosfets (the power transistors). Testing for shorted mosfets may be another next step.

[@cpoco]

Awesome! Very clear instructions (which is very much appreciated). I have a surround sound amp that has been out of action for some time now that I still can't figure out what the issue is... the front display comes on but no sound out of the speakers. Hopefully I can learn from you and eventually figure it out.

[@FrugalRepair]

Thank you! I hope that I can help. I'd love to hear that you got it repaired. I'm not sure I can say much about the it. Do any of the capacitors look funny?

In my early days of repair, my favorite repair was tape decks that ate tapes. I was a curious kid and figured out after disassembly of a couple that the drive belt had stretched and could no long apply enough torque. I found an old electronics shop in town and they sold me the correct square belt and my tape deck was back in action. The belt was prob only a dollar at that time. I went on to fix a number of walkmans too. It was a very satisfying repair.

[@pacman5113]

I got started repairing things like this in the same way! I loved to visit pawn shops around Army posts. I discovered one of them had an overflowing dumpster in the back that was full of stereo components. I asked if I could take them and they were more than happy to let me have whatever I wanted. I salvaged expensive receivers, record players, etc, etc. Some of them didn't work simply because the glass fuse inside was blown. Built my first good stereo system for almost free and a little time. I learned to solder and read diagrams in the process. Eventually I built about 20 computers for my own use and learned to repair them as well. Years later, guitar repair became another hobby that was profitable. It's a great thing to learn, especially if you are not wanting to go to work for someone else for a living.

I've been repairing PC for over 25 years now. It's amazing how much good parts were thrown away over the years I have been working on it. Majority of the issues were minor fixes like the one on video and some were even ridiculous like missing jumpers or seating issue. I get that not all are savvy with fixing but things like incorrect seating should be an obvious thing any one could fix. I partially blame it on companies like Apple and other manufacturers actively discouraging people to open their own devices.

My favorite Repair was fixing a 50in Visio monitor with a friend of mine. (Unfortunately he had to order the parts of the powerboard from China and that took alittle while) but We got it working and Its still working to this day. Ever since then, Ive been collecting monitors for me to repair. My Current projects are: a 28inch Viewsonic 2858SML computer monitor that keeps blowing the same Cap (3 so far) and I cant figure out what is shorting that thing. a 50inch Panasonic TC-40AS520U - That powers up but shuts down shortly after powering up. I was able to determine the issue was a bad transistor but thanks to Panasonic they dont make it easy for you to know exactly WHAT parts (or types) of components you need other than general. I believe I have the right one, I just need to solder it and test it (I just dont have an iron tiny enough for the job i need to perform) A 50inch Samsung that works but.... the screen is physically damaged so Im going to take the power board and other board out and sell it. Love your video!

[@FrugalRepair]

Thanks! Great to hear about all of the projects. Hope you can get those two repaired!

[@jimlocke9320]

My "educated guess" is that the resistor is in series with the diode. When the diode failed short circuit, it put too much current through the resistor, causing it to overheat and fail. My suggestion would be to substitute a different diode with higher ratings: a higher forward current rating and higher PIV (peak inverse voltage). The diode may be under rated if failing in multiple TV sets. This would be a design issue, something the manufacturer should address. My inclination would be to substitute a more readily available through hole resistor (one with leads) for the surface mount resistor. However, the resistor did behave as a fuse, protecting other components. The through hole resistor might not do that. So, only replace it with an identical surface mount resistor.

[@FrugalRepair]

Thanks for your thoughts. Yes, the resistor is in series with the diode. I would like to get a schematic of this board to get a better sense of the design and perhaps, the failure. It seems to be either bad design specs or a batch of bad diodes.

[@infotechyeti]

[@FrugalRepair]

Thanks! I don’t know that model , is there any clues online? I’d start by checking for standard voltages and disconnecting boards isolate any potential short circuits. But sounds worth fixing! Are there any boards that sell a lot on eBay? That is usually a clue of a common issue.

Hey Reece, I’ve been trying to figure out what is wrong with my m65-c1, also isn’t turning on. However, the p/s is giving me a steady 19v when I tested it. Additionally, the LED that was blinking for you, well, isn’t even on at all for me. Should that be a pretty good indicator that there is a main board issue? My dad said he’d just replace the TV but I don’t want that. I really want to show him that I can use my brain to diagnose the problem and then, god willing, fix it.

Hope to hear from you, thanks, Morgan

[@FrugalRepair]

I think there is a common main board issue that you might want to research. There are some repair services on eBay that list descriptions for the repair. I’d check those first and maybe ask some questions about the repair. Sorry I can give you more since I haven’t looked into the main board on this model.

Hello - I have two 55" LG TV's that are not functioning at all. They are both model LG 55LB5550-UV. Both TV's were bought within a month of each other and they both stopped working. I have no picture except occasional flashing "snow." The picture flashes for a moment then goes away. I bought a power supply board and the TV module main board. I replacement boards (assuming they are good boards) and nothing still. Do have any wisdom you are willing to share?

[@FrugalRepair]

Did you rule out that it is the backlight going (gone) bad? Your comment about flash and goes away indicates to me to check the backlight first. Is there sound? And after the picture flashes, have you gotten close to the screen with a flashlight to see if you can see anything at all (snow or otherwise). I don't know the history of that model, maybe a common issue you can find online? If it's not the backlight, I would disconnect things trying to isolate the fault. Disconnect anything you don't need to turn the tv on. You can even (after you have unplgged the tv) disconnect one of the cables that comes out of the tcon board. This will drive half of the screen, the other side should be white. Then try vice versa. You're looking for a potential bad buffer board or lcd panel.

Even tightening the thread screw did not stop the spinning. I am an IT guy, but navigating broken electronics is beyond me. After getting the back off, I saw the male connector wire going to the motherboard was twisted and snapped. Yep, someone fat fingered it and tightened it until it snapped.

Which board do you think it could be???? Any advice is very welcomed! Thank you...

[@FrugalRepair]

If it lights up and you see the screen briefly then it goes black but sound is still there... that sounds like a classic symptom of failed led backlights. Turn it on and after the screen goes black (and you still hear sound), get really close with a flashlight to the screen and you should see an image (if you see anything at all then it means the problem is the backlight).
