Thank you for this!
I just replaced the main board on my friend's 65X900C and it was blinking green/red when I turned it on.
Then I unplugged it, put in a USB with the firmware and plugged it in again.
It started playing music while the LED was still blinking! :) Black screen still...
Now it's blinking white continuously for quite a long time. I'm worried it might be frozen. How long does the firmware step last usually?
what does this repair cost?
My KD-55X8509C went into a boot loop today and I fixed it the same day, although I may've been really lucky. I'll tell my story / experience in case it helps others. Over the past week my TV was operating very slowly (response to remote), then it started to not open apps, then it refused to even change channel input. Throughout that time I did several software restarts (Settings, About, Restart menu options) which normally used fix any problems for at least a few days, but these recent restarts weren't making the TV work any better. So as the TV was barely functioning I decided to do a software-based factory setting reset (from the menu) and when it rebooted that's when the boot loop problem happened. I'd always see the Sony logo upon reboot but the Android logo animation afterwards froze anywhere between 1 to say 15 seconds at most (typical around 4 seconds though) then it rebooted constantly. I did multiple power cycles (unplugging for 10 minutes at a time) and on power on / restart attempts I'd try both the holding power button and power and volume down button when plugging back in, but I simply never got it to force a factory reset (big wobbly circle thing that I was expecting). I left it reboot cycling for a while and it'd occasionally get to a point of just freezing on the android logo and stay frozen. After watching this video here for help I thought my TV was toast as I wasn't prepared to spend a bunch of money replacing the mainboard or EMMC chip only for it to probably play up again down the line. I even ended up in a local TV store eyeing up a replacement until I decided to just go home and try again with the Sony, even though I thought that it was junk by that point. It again did several more boot loop cycles but then the TV suddenly completed the android logo animation and it went to the factory reset menu (the start of the very initial setup process)! A glimmer of hope. However this menu was slow as hell, the music in background & the interface in general was constantly stuttering, and when I eventually managed to complete the initial setup it went back to the very start of the menu settings again!! At one point of that initial setup menu it got stuck for ages on the "checking for updates" screen, but it never found anything despite an ariel and ethernet lead being plugged in. I confirmed the ethernet was functioning by asking to read some online policy (which it had to use a web-page for to display the info). As I was now stuck in a factory reset menu loop I saw no other option but to do another full power cycle and the TV went back to boot looping for ages again. After more power cycles it eventually got to the "checking for updates" screen again (with the same poorly functioning menu) except this time I put in an USB stick containing the latest firmware update - the TV instantly started to copy the update from the stick to the TV, it then did the entire firmware update flawlessly, and at the end of it I was again back at the factory reset menu / process except this time it just worked as it should. After going through the setup process the TV was simply back to working 100% normally, well for now at least! As it's essentially a fresh install (alike a new Windows installation) it's running faster & better than ever!! I now have a lot of customisations to do again due to everything being reset, but it's alive!!!!! Maybe I was really lucky on this one as it seems to be an entirely software-based fault that was essentially fixed by having the TV's software removed & replaced with the latest firmware once I got passed the extremely janky / unstable / corrupt software from before. Obviously if it'd been an actual hardware fault then you can't update around that in software, but my point being is that boot loops can seemingly sometimes "just" be software faults that can be flashed out if you just persist with it and be very patient! Oh and shame on Sony - I don't know what their current TVs are like but these 2015 based units feel like a substandard prototype that somehow got released passed their quality department!
In my experience, the fault that occurs is not usually a software based fault. It is a hardware fault on the EMMC chip which holds the software and thus causes symptoms that appear to be software based.
On emmc or SSD chips will start developing bad blocks overtime as they age and go past their expected read write life cycles. It is possible that the new software is different in a way that it is either not using the blocks which have failed or has none critical code occupying those blocks making it seemed fixed.
If you are scared of having your mainboard fixed because the fault could come back, you should be terrified of this fix.
With that being said, please follow up with us on this because I am curious to know how long this will last.
A proper repair would be to have a new emmc installed as that will be a proper long term repair, or replace the mainboard with a new one.
If you plan on buying a new set, just be aware new sets have the same faults repair or replace, you are expected to get the same life out of both options in my experience.
@@NicksTVRepair Thanks for your response, all understood and I don't disagree with you. I have a lot of experience with PCs so I totally get the bad blocks / sectors issues. For that reason I've decided to not customise my settings anymore than necessary just to try and avoid any further data writing. I still feel that this could be a software fault alone as using PCs for comparison it obviously doesn't take much to completely brick a PC which can often be fixed with a complete wipe & reinstall of Windows or simple bios flash / reset. Plus I also know how slow the CPU is on this TV and gets behind on processing very easily & frequently, which combined with the fact that I eventually got to the system software menu led me to believe the likelihood that the hardware was ok and the software was either corrupt or just messed up enough to cause a system-perceived false process failure state / data hanging resulting in boot looping. On day 2 now and my TV started just fine and was very responsive! I know it could die anytime, and yes also getting a new TV doesn't mean that'll be problem-free, but I also like to get the most life reasonably possible out of anything and begrudge buying a replacement until I know it's not worth using anymore or was just unfixable. That said, based on how the TV is working right now it seems that it has a new lease of life so I'll take that. I'll definitely update here if / when anything changes.
@@LargeStyle hello, great repair, I have a bravia kd-55af9 which restarts in a loop every 40sec, how do you think I should proceed?
Is it still working?
@@seesikopterYes. Only problem I've had since I reflashed firmware was my PC's GPU wasn't always able to handshake with the TV properly causing it to not identify what specific set it was & only offered 1080p instead of 4K, but that could easily have been due to a DP to HDMI adapter I was using. Changed connection to USB C to HDMI and it recognises TV as Sony 4K and everything has been working flawlessly since. (Re) flashing firmware is therefore worth a try if boot-looping in case of software corruption, and it's a free step to take (aside from a USB stick). Just takes persistence & patience, but that paid off for me in the end and I'm so glad I restored it instead of giving up.
Just an FYI make sure the repair center you take it to does this type of work. I took in my xbr 49x800e to a local repair shop that claims they do software reflash but they will only try to perform a software update via usb. I explained to them this will not work since the beginning but they claimed they knew what they were doing.
Sometimes it's a software fault and a re-flash can work, but a lot of the time I have found that the eMMC itself has a hardware fault and thus has to be replaced. The other risk with fixing it with just a reflash of the same eMMC is that it can be a temp fix and 1 week or 3 months later the fault comes right back and the eMMC has to be replaced which means with a reflash a lot of the time is temporary. So if you are paying someone to only fix it for a few weeks or a few months, you are wasting money.
Hi, I just want to say thank you! your videos help me from identify the problem to fix the problem. My TV sony XBR -65X850E works again! Thank you for sharing the knowledge.
You are welcome!
OK great video, but I have a Xbr-55x900E with the same cycling issues on booting up to the android , then shutting off. I disassembled TV to the backlights
and then turned on , and noticed 3 leds on 1 strip did not light up in the boot process. So I am wondering if this is another repair issue, other than the chip repair, or does the chip solve this problem too.
Bootloop fault = mainboard failure.
The unit is probably boot looping before your TV can fully illuminate and trigger the 4 or 6 blink code.
This means you have 2 failures. Fix the LED failure first because that's the tougher one and riskier one. Then if you want to send in your mainboard for repair we can take care of that issue for you but it would make more sense to resolve the backllight failure first.
Hi, my Sony KD-55x7500F has the same problem, Android keeps reloading and back on continuously...would i do the same as your video is showing? To change the chip? Where could i get the chip?
Tks for the comments.
I can't know for sure, it's possible your EMMC needs to be replaced but it's possible your CPU is bad and needs to be replaced. Most likely the EMMC but can't know for sure.
I don't think anyone sells the chip prepgrogrammed for your TV specifically.
Is there any reason why on future TVs that the eMMC chip couldn't be converted into a form that was easily user/field technician replaceable? As I recall, there was a time when MMC (Multi-Media Card) chips were actually used as an easily ejectable memory card for storage on portable devices. Why couldn't this chip just be accessible as a card from the side of the TV where the end user or a field tech could simply just eject it and replace it with a new one? It sure seems like that would save a lot of time, energy and effort when it comes to resolving problems like this.
It would be very cool to see that but I don't think we ever will.
Hi
My sony x90e
Suddenly while watching tv
The remote stopped responding. I
Just thought it will be fine after a power reset or hard rest .
But now after the hard rest.
My tv is stuck at language selection screen. Where my remote does not respond nor the buttons on the back responding aswell.
When i use the buttons on the back of tv. The volume works fine.
Need some help
What can be done here
Hello,
Without knowing the full model number of your TV, I don't really know which set you have and won't be able to help you as much.
But it sounds like you have a mainboard fault due to the EMMC chip just like we do in this video.
You could try downloading a software update directly from sony onto a flashdrive and force update the TV. If this doesn't work however it means you have a more severe hardware fault meaning your EMMC chip needs to be replaced.
Thank you! Will be in contact!
Wonderful!
Same problem on XBR-75X900H except that here, sometime it get stuck on "updating..." Like it was doing a firmware update.
That is a very common fault we service often accross many models including yours. You will need to either replace your mainboard, or send yours in for repair. If you would like to send in your mainboard to our repair facility I would suggest you send us an email directly or fill out the contact form on our website and provide us the model number and symptoms you are experiencing with your set.
Our contact info can be found in the video description
felicidades compañero
Where can the chip be purchased or what is the exact chip model that needs to be installed?
Hello Collins0126
The part number of the chip is printed on the chip itself. But if you buy the chip, it will be blank. Meaning it won't be programmed with the operating system software you need to operate the TV. Once installed on the board and the board is in your TV, it will act completely dead. In order for it to work, you will need to program it using a specialized eMMC programmer. They cost between $300-$1,500 depending on the kind you get.
We do not sell the chips preprogrammed, and we do not recommend you purchase a preprogrammed chip and attempt to install it yourself. The replacement process requires advanced tools and skills to be properly installed. If you attempt the repair yourself it is highly likely you will damage the board beyond repair.
This is why we offer an affordable flat-rate repair service and will perform this repair for you with an almost 100% success rate.
If you have any additional questions, do not hesitate to reach out.
Thank you
Or you could just buy a new board and flash the firmware get it from Sony put it on a usb no need for that expensive machine they do a chip replacement just buy the.m board they Range from 100-200 dollars new
Hello, I recently switched from Direct tv to Fios TV and I'm noticing that when I start the TV I see the sony logo then the android logo and eventually the TV starts up(I have never seen these before and Ive had the TV for quite a few years) . I never had this issue happen before, not sure if switching providers had anything to do with it or is there an issue with my TV. Have you ever heard of this? Can this be shut off? Thank you
There is most likely a power saver mode that is on which completely turns your TV off 100% when not in use. Most likely that was no on prior. There should be in your settings an option for the TV to stay on and when powered "off", only the screen and backlight turn off but the TV stays in a partialy on mode. This way when you press the power button the next time, the set turns on very quickly.
Every version of the sony software is different, depending on what version software you are on, the navigation to that setting may be different.
is this the same tv with backlight problem..
It is, we had a backlight fault and for the mainboard we service them so we just put in a customers bad mainboard in the TV to show the cycling fault and then repaired it.
@@NicksTVRepair Thank you for sharing 😊🙂...Can I ask for a detailed video about flashing software directly in NAND.
I have XBR-65X950H similar problems on and off red flashlights
Hello,
A red flashing light is actually very different. And the very specific amount of times the light flashes will completely change what is wrong with the TV and what needs to be done. A 7 or 8 blink code = mainboard, a 4 or 6 blin code = LED strip repair.
It is very important for you to count exactly how many times the red light flashes. Once you have that number, let me know and I can confirm what your fault is.
@@NicksTVRepair how would you/could you fix the 4 red blink code?
XBR-49X800D my Sony tv turned on it doesn’t turn back on. Then maybe hours later has a mind of its own. Turns on. Is it the same fix? I didn’t see you showing how to open to get into the tv. If I take it to shop how much you think they would charge me? I don’t want to get rid of it. Tv color is amazing.
Can it be the plug on cord that might be bad?
I can't give you a quote without really knowing what is wrong with the set. I believe you may have a bad mainboard but I would suggest performing a software update and factory reset first as that may be all you need to do.
Your TV is not the same as the one I work on in this video, so the back cover removal process would be very different.
The plug and cord are not bad, I have never seen that be the fault on any TV before unless it was due to physical damage from a pet chewing through the cord.
@@NicksTVRepair Thank you for replying. Appreciate it.
What about if replace whole main board ?
The problem with that is the boards are no longer available for sale. If they are available they are extremely expensive. There are some sellers as well on ebay with used boards but those are often defective and don't work.
can i buy from u programmed emmc for sony 55w800c?
Hello Crypto dream
While we don't technically have them for sale, I think we can do that. Please send us an email directly or fill out one of the forms on our contact us page and provide the full model number of the TV and part number of the circuit board you are trying to fix.
How many people have the equipment at home to do this? What am I supposed to do with the information? I might as well taken it into a shop and pay a bunch of money.
I think you may have missed the point of the video.
We are showing you how you can fix it yourself so that you don't have to pay a bunch of money as you are suggesting. We give you the information you need to diagnose the unit, and identify the defective part. Now you know you can either purchase a replacement mainboard, and install it to fix your TV, or send your defective one to our repairshop and we can do the component level repair for you. We send it back and you install it back into your TV. This way you can get your TV back up and running for a fraction of the price of a new one and or cheaper than if you had someone else do the diagnostics and part replacement for you.
Does that make sense?
Hi, i have the sony xbr 75x950h. The tv turns on android boot logo comes on then goes to main tv screen. After about 10 to 15 seconds it shuts off and gives me 4 blinking lights. Id like to try to repair it, if it is possible. Any suggestions?
Most often the 4 blinks are LED backlight failure. Sometimes it's the LED driver board that fails. Since the driver circuit board is much cheaper and easier to replace I would recommend trying that first. If that doesn't work then it would suggest you need to replace your LED backlight.
Well I hv sony tv come on and some time go to main screen and then turn off and start blinking red light 6 time .. what could be done to fix the issue
This is an LED failure. Replace the LED strips to fix it.
I have an XBR-65X900F that is doing the bootloop is this the same fix?
Yes even though your TV is a bit of a different newer model the fault is the same. You wouldn't be using the exact same chip of course, but it would still be an EMMC fault.
We do have a flat-rate repair service for your mainboard which comes with a 1 Year warranty on the repair. For more info/details check the listing linked below:

Good afternoon, could you help me? I have this TV, but I've never been able to enable the Sony logo to appear as soon as I turn it on. Could you tell me how I can do it? You seem to me to have a good understanding of these TVs. Thanks.
"I've never been able to enable the Sony logo to appear"
A quick google search brought me to the sony support site and reads the following:
"Go to Settings
For models released in 2019 or later: use the Quick Settings button
On the remote control, press the (Quick Settings) button.
Select (Settings).
For other models: use the HOME button
On the remote control, press the HOME button.
Select (Settings).
The next steps will depend on your TV menu options:
Select Channels & Inputs → Info banner → set to disable
Select Watching TV → Info banner → Hidden or set to disable
Select Channels → Info banner → Hidden or Off
Select Channel setup → Info banner → Off or set to disable"
@@NicksTVRepair Unbelievable but disabling the info banner fixed my problem and the tv doesn't power on, on loop anymore and the videos now play
Do you still fix the problem
Yes we do
Emmc dump files already flashed?? on your new emmc??
Yes the EMMC is already programmed.
What about RPMB, does netflix work, and screen mirroring and other smart function?
Most smart functions will work, Netflix, Hulu and prime video however will have issues.
We recomend using external streaming devices to use those apps.
@@NicksTVRepair why do the apps error after the fix? thanks
Hi do you copy the unzipped latest firmware form sony to new EMMC chip?
no that's different software. The software we use to program an eMMC chip is taken directly off an eMMC. We clone it from an eMMC chip that was removed from a good working board that has been factory reset typically.
@@NicksTVRepair Thanks
Xbr65x900f blue screen sounds and movements but no picture..replace the man and t con board still same..😢
Rayon,
You may have a panel fault. This is an odd symptom that I am not familiar with. I would recommend you reach out to a local TV shop to have them take a look at it. This one may need eyes directly on the set.

Same exact failure it's just your eMMC chip triggers the fault with a bit more delay than the one in the video. The faulty part and repair are still identical.

Hi, what happen when you put a new emmc chip ? Is it just the app like netflix and youtube that doesnt work ? the rest is just the same ? you can still read a video from a usb key plugged on the tv ? thank you !
You can still use any app you want, you just have to do it from a different device plugged into the TV like a firestick, roku, apple TV, your cable box has apps as well you can access.
The native apps however and it's not all of them but a few won't work due to encryption. You can still play a video from a USB, you can still use all of your HDMI ports, you can still use your antenna, you can still access apps but you have to do it using an external device which most likely will navigate faster, and smoother than the built in app anyways.

Sorry we don't have a dump of that eMMC. We only service USA models.
I have a Sony XBR-77-A80J have similar issue shows upto sony logo and then Shuts off and tries to boot up again and shuts off... 4 blinking red lights. sometimes It will get pass the sony logo and get into Andriod or even menu but eventually it will shut off with a Clicking sound and 4 blinking red lights. cycle repeats. can it be the Mainboard EEMC or power supply >?
Unfortunately, 4 blinks is going to typically be the backlight. Since this is an OLED model the backlight is embedded into the screen and can not be replaced.
There is a tiny little chance it's a power supply or LED driver board fault but in my experience most often it's a panel failure. (panel = screen/LED backlight)
@@NicksTVRepair can you do the BL_ERR bypass with this TV or no ?
Unfortunately, you can't do the BL_ERR bypass with this one, well you can but it won't work. However, I am responding to you again because I just had this exact model come into our shop also with a 4-blink code. My tech deemed it a bad panel, but I may be calling the customer back soon as I am taking a closer look at it right now and there is a chance it could be a power supply fault. I am still working on it and testing further. The issue is that OLED models are harder to diagnose and test since the LEDs are embedded into the screen.
Do you still have this TV? I might be able to help you fix it but will need another day or two to get more info on it.
@@NicksTVRepair yes I still have the TV.. Keep me posted waiting to hear from you…
@@NicksTVRepair please keep me posted on your findings with the TV Sony XBR-77-A80J hopefully you can do some magic to it and save it :D as I still have the TV and waiting to see if you are able to help me save the TV. TIA.
Soft ware cost
The too to program the chips is very expensive, the software itself that we program onto the chips, you can't buy, Sony doesn't sell it, we had to get it from a new board.
Brother how to cpu programming rpmb key .mtk cpu
I am not sure I follow. Are you talking about programing the CPU? If so please contact me directly I would love to know / learn how to do that. Do you have a video showing how to do that?

I have a solid blue light and the sony logo twice then nothing :(
That is a more unique fault but most likely still related to a defective mainboard. I would recommend you reach out to us directly via our email or by filling out our contact form. Both can be found in the video description. Please provide your exact TV model number so that we may be better able to assist you.
Same problem yes 😢
This is one of the most common faults we see with these Sony sets. If you want help to fix your board, we have a link in the video description!
Jeeeezush hang on a minute while I set up my tv repair factory with all the professional gear and machinery in it 🙄🤬
Haha true, for this one it does require more advanced equipment and skills if you want to fix it yourself on a component level.
The selfish goal here is that I am advertising my services, the less selfish goal is that I am also showing you a step by step process of exactly how you can fix it if you do have that equipment or if you are a TV shop. I also want to show less tech savy DIYers that even though all the mainboards are out of stock, you can still have your TV fix and save money, you might just need a little help from the pros in that instance.
Any whtsapp or any communication num pls
Sorry we don't do that.
If you would like to communicate with us, please do so via the contact info provided in the video description.
