Hi Nick, thanks a lot for the video, I got my main board out, I just want to find out if you think that is my problem, how long does the new main board take to get it?
We have 2 options linked in the video description, 1 is a repair of your original which is cheaper, that is usually 3-5 business days for the repair + shipping both ways, and we have some for sale as well which is a more expensive option but also would be faster. We typically ship them out within 24h of the purchase and the speed of shipping depends on the shipping speed you select at check out and your location. 2 days with priority mail shipping if you live nearby.
You can check EMC without removing using ISP connection to verify is it any software issue or EMC life is completed I’m doing this job almost 10 year but I’m very happy to see you’re doing well
Hii
Do you have any video tutorial to learn how to do it ?
thank you
You can use ISP but one of the components on the board will block you from reading the emmc chip, it must be removed if you can find which one it is
@DSM090
Just buy the XGECU T56 Pro with the 156 emmc socket. Set the settings to 3.3 volts in the options folder and 8 MHz. On the top of the program to the left, choose the model number of your emmc. Then click analysis IC at the bottom to the right to make sure the emmc you have in the programmer is good or not, assuming you do have a good emmc. If the emmc is good, go to the top and click read. After reading just name the file whatever you want but don't change the ending of it, for example if it ends in the word BIN do not change or delete it. Now, insert a blank emmc into the socket and click erase, then go to the top where it says project p and open project. Choose the emmc file you saved or a file called ghost and write it to the blank emmc.
Why is the "setting have bus with 8-bit" instead of 1 bit.
I noticed that the emmc you're reading is from samsung, I never seen an emmc chip from Samsung in a Hisense TV
Hisense usually uses SKHynix chips. So if you take a look at the video the first chip we put in was SKHynix and that was the original chip that was on that bad board. The second chip taken from the known good board was probably a repaired board.
As for the 8-bit vs 1-bit, I believe that is the read speed. So 8 is just faster than 1.
@@NicksTVRepair
Thanks for answering my question. When I try to use 8-bit with my T56 it doesn't read the Hisense TV emmc chip
Hi Nick, I have the exact same TV - the TV loads to the main screen allows me to quickly scroll then shuts down in roughly 10 seconds.....are we looking at the main board your working on in this video or the power main board??
If you have the exact same TV as I do in the video then you most likely have a mainboard fault.
The board we are fixing in the video is the mainboard. The power supply board is the one that you plug in the power cable that connects the wall outlet to the TV.
Hi, my hisense stanby light flashes 5 times the stays on...tcon or power supply board? Any thoughts
It's best if you provide the model number of your TV but based on what you described I would say neither of those.
Most likely it is a mainboard fault or panel fault. I would need more information to be able to better answer the question.
i have this exact tv, overall its been solid but about 1 year in, the eeprom failed and hisense thankfully sent a tech out to replace it. several years later we're in 2024 and the tv is just soooo laggy. i am doing a factory reset today, but am going to see if this addresses how slow the tv runs...
Factory resets and software updates are always good to do. If neither resolves your fault then it is likely that your mainboard is defective and the eMMC chip will need to be replaced.
We do have a flat rate service and offer a 1-year warranty with all our repairs if you are interested in sending it in.
Hi i have a Hisense 43h7050d that needed a wifi module replacement. Upon replacing it, the TV no longer powers on. The LED light is on but neither the tv button nor the remote powers the TV on. Any recommendations for how to proceed? I am thinking about replacing the main board as there is power. Any help would be greatly appreciated!
What you are describing is one of those bizarre situations with no explanations. Replacing the wifi should not have caused your mainboard to go out. With that said I would agree with you that your next move should be to replace the mainboard. However, I will also say this. Once the TV is working, don't use the TV's built-in smart features, get a Roku or Firestick. Even if the TV already is a Roku TV or Fire TV it is best to use each company's own external device. This will #1 help extend the life of your TV by using the chips inside the external device more than the ones inside the TV and thus relieve some of that workload off your TV.
#2 The external device will have a version of the apps that are superior and will allow you to navigate faster and smoother.
Hello Nick i have a Hisense 75H6510G with same failure and looks like mainboard part is 273565 and is not longer available on sale, could you fix it and if you have a new one which one is the cost for the new one
I don't have mainboards for sale for the 75" model only the 70" version, but I do fix the 75" mainbaord. Here is the repair service listing which we do provide a 1 Year warranty with the repair:
nickselectronics.com/products/75h6510g
Do you really need to program with jtag, or can you just install it? will the TV work or is that where FW, etc is stored?
The eMMC chips when you purchase them are blank. It's like buying a hard drive. When you buy a hard drive it doesn't come pre-loaded with the MAC OS or Windows 11 already on it. You have to install that program on the harddrive and then tell the motherboard's bios to use it to boot off when the computer is turned on.
It's kind of the same thing here. If I put a blank eMMC chip on the board, I wouldn't be able to turn the TV on. It would act as if it's completely dead.
This is why these repairs are difficult, you have to have that very unique software that will allow this specific TV to turn on. There is almost 0 cross-compatibility with the software either. Getting that software in the first place is half the battle.
Hi, my Hisense 50H78G power light blinks 5 times and then stays on. No picture or sound, and nothing shows on the screen when I flash light on the TV. Should I just go ahead and replace the main board? Thanks in advance and really appreciate your work.
Based on the information provided yes I would agree that you most likely have a mainboard fault. However there is a small chance you could also have a panel fault.
What software and equipment do you use for checking the MMC chip?
Most often it is the Easy Jtag+ but we have also been using this tool as well recently:

i have the same issue. model 65Q8G. any remedy for this issue. can i do diy?
Hello,
If you are experiencing the same issue with your TV, then most likely you have the same fault. Your mainboard is going out and needs to be repaired. Unfortunately these mainboards are out of stock, so replacing it is almost impossible. If you did want to send it in for repair, we should be able to fix it.
Please contact us directly if you would like to send it in for repair (contact info is in the video description)
Hi Nick, I wish I would have seen this video sooner.
My 70inch hisense tv turns on then freezes at the logo and then turns off. I took it to a repair shop and the guy said it was not worth repairing. I did a little research (emphasis on little) and I ended up ordering a repair kit including the main and power boards. I came across your video as I wait for delivery of the kit. I thought it was going to be a simple matter of changing out the main boards but now I realize that the new board is going to be clean. What do you suggest I do?
The replacement board is going to be clean? I am not sure I understand. If you are getting a replacement board it should work fine provided it's working and not broken. Now the only downfall is you may not know how much use it has had in the past and how much longer it will last, which is the advantage of the repair since we put a brand new eMMC chip on there.
When you get it just make sure to do a factory reset and software update. As long as it goes through both no problem then you should be fine. If it hangs up on the reset or software update then you know it was/is going to go out soon and should return it.
@@NicksTVRepair I will cancel my order and send you the board. How much will this cost me?
@capricarlo what ended up being the problem? Have the same issue!
Advanced level, nice job.
Thank you!
That's how we start most of our repair services.

Nick great video I have a 58H6570G HISENSE its turning on and shows the screen Hisense android tv and shut down . I tried reset from power button and from remote didn't work. is there a hard reset from the motherboard.
Actually there should be a reset button on the back of the TV near the HDMI ports.
@@NicksTVRepair Thank you for responding I checked and I don't think the model that I have has that reset button I have been looking for it but did not find it.
I watched few videos where it showed how to reset the remote which I tried and it also showed how to reset the TV and I tried that but that did not work I believe the TV got reset and it went ahead from the Android TV screen and started showing me the option to connect to the Wi-Fi and connect with the Google.
I did connect the TV to the Wi-Fi and as soon as I move forward with more options it keeps getting shut down and I had to restart hit again multiple times.
Now when I restart it shows me the Android screen it moves further and shows me my Google account I move forward with all the acceptance of agreement and changes and then it keeps resetting and shutting down.
I thought that the remote could be the problem so I removed the batteries of the remote and kept it on the side and downloaded remote TV app from the high sense on my Android phone and tried to connect the TV with that app and was able to successfully connect it and move it forward with few selections of the setup but then again the TV keeps getting shut down every few minutes.
Can you Help and guide me how I can find a hard reset button on the motherboard which would help me to reset this back to factory settings I'm an electronics engineer and I'm sure if you can guide me through the steps I can reset the motherboard which might help to resolve this problem thank you.
@@NicksTVRepair I was able to get the TV to get to home screen connected WiFi and LAN , logged in with google account but as soon as it gets to Home screen it shuts down any recommendations.
Model- 58H6570G HI SENSE
@@NicksTVRepair Hi Do you think you can suggest more the TV is now turning on but there is not reset button on this model and we tried everything else but it gets to home screen and shuts down. I just thought the way you posted the video you can help to fix it or repair it- i have a 58H6570G HISENSE
@@NicksTVRepairhey there! Great Video! But yeah, I can’t find ANY RESET button ANYWHERE! The model I’ve got is: 65H6510G Mine is turning on, showing Hisense Android Tv (all along the red light blinks twice), and then it auto powers back down. I’ve done the unplug & wait & plug back in= 👎🏻 Then, unplug & hold power button on tv down for 30 sec, plug back in & wait 60 sec, then power button tap to turn on & same thing…2 red light flashes, Hisense Android Tv on screen, then auto power down. I live in a small town, no repair ppl around these parts; so I’m thinking to replace the main board because 🤦🏼♀️ can’t do the whole replace emm…(emm whatever that thing was called), so yeah….I need to find a way to HARD/FACTORY RESET this darn thing (if you may have found a way to do so) or am I stuck replacing the entire Main Board? I have no clue how I ended up buying the one freakin’ tv model that ain’t got no factory reset on the actual tv itself. 🤦🏼♀️🤦🏼♀️🤦🏼♀️ I’m pretty electronically inclined, but where can I get a new main board from? Does Walmart sell these things or Best Buy? Or, do I HAVE to order one? Thanks so much again for your video! It’s an eye opener, but I still have SO MANY QUESTIONS!!!!??!?🤣 hope to hear back ASAP!
My 75h6570g tv is stuck on the main screen logo with pixilated line across the top
I would recommend you send me an email directly with a picture of the line you are seeing on screen. This way I can help you identify if you have both a panel failure and a mainboard failure or if the line is perhaps caused by the faulty mainboard. Our contact information is located in the video description.
My Hisense A6 UND 4k 70 does the same thing, show Logo then it shuts off 😢
It's fixable per the video! We have a mail-in repair service available, we can fix the board for you, and we also have the boards available for sale. The links to our services and boards for sale are in the video description
I have 2 power boards I purchased for the 70H6570G if you would like them. Seems my issue is possibly a main board. Only boots up for 1 second then shuts off and continues to cycle indefinitely.
Yeah, it sounds like a mainboard fault.
I appreciate the offer but do not need the power supply boards as I have never encountered a bad power supply for this model before. 100% of the time I fixed this TV, it was 95% of the time mainboard failure and 5% of the time LED failure. Because of this, I do not have a need for a spare power supply.
If you want to send in your mainbaord for repair, we offer a 1-year warranty on our services and also have them for sale if you would rather not send yours in.

@@NicksTVRepair what's the turnaround time for main board repair?
3-5 business days is our advertised turnaround time for most repairs.
@@NicksTVRepair with the repair do I keep all my data? Do you just transfer the data to a new chip or will it be more like a hard reset?
The eMMC chip that holds all of your data is corrupted and broken on a hardware level. We would not be able to retrieve the data from it. That chip will be thrown out and a new one with a fresh initial factory setup version will be installed instead. So it would be like a hard reset.
What’s goin on bro my hi sense turns on shows android blinks red at the bottom and turns off. Is it the main board/ mmc piece
Hello,
The fault you are describing does sound a lot like a mainboard failure due to a defective eMMC chip yes.
Hi there, my Hisense 70H6570G tv won’t turn on. The red light comes on, but it will not turn on. The light blinks every 30 seconds or so, but it won’t turn on. Not a problem with the remote (fresh batteries). Everything I’m reading online indicates that it might be a main board issue. How would I go about diagnosing/fixing that?
The only other reason this could be happening is because you have an LED backlight failure. To test that you would need an LED tester.
Otherwise, there aren't any other steps for you to take. You can either purchase an LED tester to rule out your LED strips (not likely) or you can send in your mainboard for us to live test and fix for you. We offer a flat rate service which is linked in the video description below. If we find the mainboard to be fully functional, we will simply send it back with a refund minus our testing bench fee.
Please contact us directly if you have any more questions.
Thank you
Hello Nick I have the same problem that you showed in your video. How could I have this problem fixed
Always interesting. just ordered a jtag plus, my sony 65" has the same error.
Do you have a good board to copy software from?
Very impressive!
Thank you!
Could u still use the TV and apps if u just install a power bored
So the circuit board we are fixing in this video is a mainboard. When you replace the eMMC chip, a small amount of apps will no longer work. However, a good portion of apps will still work just fine. Using a Firestick, Roku device, Apple TV, google Chromecast or another similar device will circumvent this issue.
If you replace the mainboard with a used one, you won't have that issue but you also risk having a repeat failure soon.
If you replace the power supply (I have never seen one for this model fail), it will not affect the apps.
@@NicksTVRepair
Why can't you get all the apps to work are you missing the key for it, can't it be uploaded to the emmc after the read and write is finished
Hello I have a problem with my Hisense smart TV vida 52 inch it's keeps going on and off when I turn it on like every after 2 minutes at times 2 hours
Mhmm, intermittent issues usually means it could be a lot of different things. I would suggest providing me with the model number so I can get a better idea of what TV you have. Hisense made a lot of different tvs. Knowing which one you have specifically would help me better understand what issues you may have.
@@NicksTVRepair Model 50A6100UW
It's Modal 50A6100UW . thank you for the great work
You guys are good!
I appreciate the kind words
Got the same tv. No lights no power tried different batteries and cords no power at all. Power supply?
It could still be a mainboard. The eMMC chip is known to sometimes fail in a way that it produces a no power symptom. I really wouldn't know for sure unless you brought in either the TV or sent in the mainboard and power supply to our shop for testing and troubleshooting.
Thanks. no lights even on the sensor on the bottom by the logo
So this is what happened to my tv I called support they told me to update it now it doesn't turn on at all so I was wondering if I buy a new Main bored it fixes everything
It's crazy because it was downloading the update but I just didn't turn on after
Yeah that's common and it's almost certainly because of the mainboard.
Now as for "fixes everything", I don't know what other issues you have so I couldn't guarantee it would fix "everything"
@@NicksTVRepair and when I first had the problem I got a notification on my tv about storage delete to save I was wondering why is that because I only had 3 apps downloaded so I turned off the TV to fix it then the TV would try to boot just like this video but shut off I call support they told me to download an update it was downloading then it restarted just never turned on after that I did everything they said I don't know thanks for replying
Yeah that for sure mainboard failure
Can I send you a Hisense Main board with this problem for repair?
You sure can! We have links in the video description to our flat rate repair service.
We offer a 1 Year warranty on all our services! If you have any questions, don't hestiate to reach out. We also have our contact us page linked in the video description as well as our contact form.
Nice job, i had one of these with the same issue. Hisense would not help by sending any firmware.
Yeah that's why we had to purchase a new board first to grab the software from it before we could shoot the video and do the component level repair of the original defective mainboard.
But now that you have the software, you have it for life.
Can you elaborate on what you used to do thus job. It seems like an infrared heater that you program a heating profile. Am I right, secondly you have a vacuum pickup. Is this part of the infrared heating tool? What programmer do you use to read and write the emmc?
How much do you sell the main board
@@angelosanagnostou5550
The rework machine we use for the soldering work is a ZM-R5860C BGA rework station upgraded. The vacuum pickup tool is built into the machine. It uses both infrared heating and convection.
We use the Jtag Plus for the EMMC reading and writing.
Hey nick my hisense tv has a white background, and I don't know what to order. Model number is 43h4030f4
I am not familiar with this model but with a quick search on google I found this tv model only has 1 circuit board. Not knowing what is wrong with it I would believe this to be the natural first step to take.
If that does not resolve the fault then you may have a panel failure which would require a hands on repair from a tech.
75h6570g screen will flash then go dark and blinks 20 times any idea thanks
That sounds more like a backlight failure
Do you know a good seller for the led strips
I don't have these otherwise I would point you to our store. The next best would be Shopjimmy:
www.shopjimmy.com/hisense-svh700a31-led-backlight-strips-8-70h6570g/
70H6570G.
TV turns on and shows android screen for a second then turns off and is followed by 3 flashes on power light.
Is there a fix?
Mhmm, I want to say that it is a mainboard fault but I fear it could also be the LED backlight. You would need to test your LED strips using an LED tester. If you want to send in your mainbaord, we can also live test it in our TV and confirm the fault. If the fault is with the mainboard, we will proceed with the repairs, if it's fully functional we will send it back to you with a refund minus our bench fee.
For more information on that, you can visit our repair service listing linked in the video description, or if you have any more questions, you can reach out to us. Our contact info and link to our contact form are also in the video description.
Great job can you send me the part number?
Hey Felix,
All of the information is provided in the video description. We have the part numbers, board numbers, and links to both new modules for sale that you can outright purchase, or if you want to save money, and spend less, you can send in your original defective mainboard for repair.
I don't like to provide links in comments because it is a bad habit as it is easy to impersonate on RUclips and scammers are everywhere! This is why I typically refer people to just check the video description since that is where we put all of the information.
