Coppell TV Repair's video channel at RUclips serves two main purposes: to prove our customers (and potential customers) that the boards we process are indeed functional and to educate general public about certain DIY troubleshooting techniques and repairs of LCD, LED, OLED and plasma TVs.
We do not make a video of every board we repair - only certain ones - and we do not aim to be an all-around education solution either.
We try to organize videos so that one can find the educational ones more easily; we'll either put them in a separate group (if RUclips allows that) or just have a keyword such as "HOWTO" or "how to" in the title.
Then again we often include useful information when displaying a board's functionality so it probably works well to check everything that is related.
Happy hacking!

I may have messed up the models in the video, so here are the correct ones: The board shown is for M60-C3. it might as well have been from M70-C3, they are compatible. The TV itself is P702ui-B3. It is nearly identical with M70-C3 so the main boards from one can go to the other, but there will be difference in the picture in each case because the dynamic LED drivers work slightly differently, m...

I’m curious, why do so many of the original EEPROMs fail on these TVs?
How much to fix one I have this monitor wo t power on.....
There can be different reasons why the monitor is not starting - bad power supply board, bad main board, bad LCD, maybe bad T-CON and maybe bad LED driver....haven't seen all of those situations individually yet, but definitely the first three...so I can't tell you how much it will cost to fix without knowing which one is bad. If you want to have us test and possibly repair the power supply the link is in the video description. If the main fuse on the power is open then the monitor will be totally dead no matter what and the power board will be bad too. Do not attempt to replace the fuse, it is a result, not a source of the problem.

Thank you
Thank You Post
Do you need the remote, because I'm missing the remote. When I plug it in
I do not understand the question, sorry. We do not need any remotes, we have plenty.

Hello! After repair kit i’ve got picture but red sprayed on the increase contrast and fets are extremely hot and some diods too..Please do you know whats the reason for it?Nice video btw..Thanks in advance
My guess is you have a damage to a component in a control circuit for some of the FETs and they do not work in proper mode - usually a resistor or a smaller switching transistor that is semi-burned and changing the activation levels of the MOSFET. Could be also something that was scratched off during work on the board, I've seen both happen at times over the years. Unfortunately can't be more specific. It's one of the things that, when it happens, you are very lucky it didn't cause immediate failure the moment the board was put to work....but then you have to find it and that can be rather difficult without at least a good working board to compare against, let alone a scope with known wave forms.
@@coppelltvrepair Or it’s about shitty parts from Aliexpress..i have changed ic502 and q531 and clean all the contacts and tight all screws,still the same..all the resistors around fets are ok…maybe the panel is half dead?Maybe i should lower the vsus?Thanks on quick response btw..
@@TheDevilcuteGr Yes, if you ordered parts from China it can definitely be that too. I assumed you used our repair kit with parts that we use and know to be good. We did receive a fair amount of bad parts from China over the years despite of working mostly with the same vendors.
I have no power at all on the cold side. On hot side I've got 315V on pin 7/8 of the ic. Also on pin 1/4 of the transformer. I replaced the known a6069h ic, and the resistor r7900, checked the caps around it and the zener diodes Iam out of options. Maybe transformer broken? Dps-162kp-1
Hardly the transformer. Not impossible, of course, but not likely and relatively easy to test. When transformers fail they do one of 2 things: short out (burned insulation on the copper wiring leading to short and wire shortening leading to lower resistance/higher current, which in turn lead to overload and burnout) or burn out break the circuit, which is established with a simple meter. Anything else, while always possible, is very unlikely.
Good, informative vid
Hi. I have a BN44-00874F with a blown CP809 blue capacitor. I was thinking to just replace the other (3) as well (CP810, 811, 812). I can't quite read whats printed on the other ones, I believe it says R221 2KVK 1851? Did you replace with a different value? Besides that and the main fuse (T6.3AH250V) located at FP801S, do you recommend any other parts to be replaced? Oh, one last thing... the power button on the bottom middle part of the screen frame looks like it shorted out. May or may not be related to this but im having trouble removing it to see the whole board. Any issue with those? My TV is the UN82RU8000 btw.
I recommend all the parts that we sell in the repair kit for this board be replaced at the same time. In some cases you may need more than what's in the kit too. Can't say anything about the power button. It hardly ever needs attention.
I fixed mine by turning off pixel cleaning every ten minutes to off
Personally I would sawzawll what's left of the fender off and keep going. 😆
Does this use the same power button/joystick as the 34UM95? Looking for the right part for the monitor in your video, which you mislabeled slightly 68, not 69. ;)
It is very similar, but I do not think it is the same - I believe the connectors are different and the resistances corresponding to different buttons are also different. Not 100% certain, but you should be able to easily tell if you have the old button from 29UM68-P. And if you have a faulty button board that is different you can send it to us for repair.
In this video we see that this white silicone (potting compound?) around the PFC MOSFET was removed. The PSU seems to get returned to the customer without this compound restored. Since I have the same PSU repaired, I am asking myself what this white compound is used for. When they put it on vertically mounted resistors or on on axial capacitors mounted laying down on the PCB the purpose is clear: To prevent the effects of vibration or to prevent that these components move. However, the MOSFETs are mounted to a heat sink and should not move at all. Also, in the video we can see that there is a diode mounted to the same heat sink which did not get any potting compound at all. So, my question is. Do they put the compound to the MOSFETs for some else purpose? E.g. to limit the damage if the component blows? Or to prevent dirt accumulation between the high voltage legs?
I will not answer the question on why Samsung is putting silicone on the MOSFETs. It should be them who should answer that question so there is no doubt for making guesses. I will say, however, that they have been producing power boards for decades before starting to use the said silicone and those older boards often lasted a whole lot longer before failing compared to the new ones Which is one reason we do not put silicone back after repair.

I have a Vizio E550i-B2E with the same symptoms. Brought it to a fellow ham radio operator and he soldered it. Now it works great. Thanks!.
Thank you for your video. I got a replacement M60-C3 power supply for a Vizio TV that a neighbor gave me and the TV worked for at least 5 years after that. In May of this year, I saw that part of the backlight near the top and bottom edge would be off, like a dark shadow in a 4 inch or so area across it. I pulled the plug for some seconds and plugged it back in and that reset made it work again. However that was a red flag of it failing and within a handful of weeks, it was dead. No picture. So I found a replacement board and bought it and replaced it and it's been working again for about 6 weeks. However, twice now in the past two weeks, I've seen a similar part of the display near the top backlight off and again unplug and replug and it resets. But I am highly nervous that this probably refurbed board is soon to fail. I wrote to the selling company and sadly they only have 30 day warranty. I wrote to their tech support and I'm waiting for a reply. I haven't looked at the caps yet. I honestly don't remember with my old board, if the caps were bulging. Not that I noticed. Is it possible that something else is putting stress on the PS board to cause it to fail? Update: A tech from the shop for the PS board is saying that it's possible there could be some failing in the LED driver board or Main board causing the symptoms, which, in turn, can cause the PS board to also fail if not repaired. Update 2: I was able to get an LED Driver board for a very reasonable price. I plan to replace that first when it arrives.
As far as possibilities go nearly everything is possible. I do not think there is anything that presses against the board in the TV nor do I think this has anything to do with capacitors. You got two old boards that have worked about the same amount of time and one of them may or may not have been reconditioned and it may or may not have been done properly (if at all). So it is not surprising to get about the same life expectancy with about the same failure symptom out of them.
I have a 65" TCL TV Service No. 65S421TCAA --- If you let the TV sit off for a day or so, when you turn it on the TCL logo will flash full brightness for literally 1/60th of a second (I recorded slow motion on my phone) then go black. You can hear the menu sound effects, and it works "just fine" but no picture. Sometimes if you hold your head just right, and the angle of the room light is just right, you can make out SUPER DUPER FAINT - I MEAN REALLY FAINT text on the screen....sometimes. After researching - I'm thinking it is something to do with the TCON board - any ideas? THANK YOU!
Im having the same problem with my 65 tcl 65s455-CA
Basically, the TV tech that brought you the TV is completely useless as a tech.
My same TV powers on then shuts right off after 4 seconds is that the power board (only gets to Vizio logo and shuts off)
Usually it is not the power board.

Hi i got a samsung odessay g9 it was working perfectly but suddently it lost power i tried everything but its not even turning on. can you please suggest what can be the issue?
If there is a LED that turns on and shows color then I'd say the panel is likely bad. If the unit is all bricked and shows no signs of life whatsoever then it may be a bad power board or a bad main board. Both are preferred to a bad panel.
Hi I wanted to thank you for this video. I found a tv in the alley behind my house and was able to fix it using this. I’m glad it was saved from being thrown away.
Hello I bought this monitor, whenever I connect the display port cable the display shows as nvfailsafe and the resolution is set to 640x480 I've tried many dp - dp cables and a mini dp - dp, I'm confused
i have a question if youd be able to answer. i have a g9 and it boot loops every 15 seconds even with a new board and power supply and everything else unplugged. does it have to be connected to a tcon and mine could be bad?
As you can tell by the messages at our website we are currently in vacation mode. I can't tell from the top of my gead if this could be caused by the panel, but I am quite certain there are plenty of Samsung models from the QN series - if not all - that power cycle when the LCD has gone bad. This was not the case in previous generations, not to mention the LCD panels did not go bad nearly as often until about 2015-2018. All major OEMs figured that LED strips and panels are the two things not worth replacing, so those are the two things that now tend to fail the moat. Though, again, that can be model specific.
@@coppelltvrepair thank you for answering then while away i appreciate that. just desperate since ive tried it with everything disconnected as a diagnostic step and connected again, with a different power supply and main board and it acts the same with the boot loop. dont know if i have a second bad power supply or the tcon is bad and the board refuses to boot without it. samsung told me to find third party repair and no one works on displays that i call

@@brentbarham3157 My 2c guess would be that you have a bad panel. The T-CON board is not likely going to be bad - it is possible, of course, but usually ends up being waste of time investigating like with your power and main boards.

Hello! I have a Vizio M60-C3, and everything works, EXCEPT, there is no light coming thru the display. I have sound, there is even a picture, but no light whatsoever. I used a small flash light and can see an image.. My question is, what would I need to replace to remedy this problem? The LED's themselves, or the LED driver/power board? I appreciate any info or tips you can provide! Thank you for your time, and I hope you have a wonderful weekend! Kindest regards ☺️
No way of knowing from here if your LEDs or the LED driver is bad. More often than not is the LEDs, but I've seen the LED driver go bad sometimes too. It should be fairly cheap on ebay so you may want to replace it as means of elimination. or go for a new TV altogether - replacing the LEDd is a PiTA and first time users often mess it up.
