Hi Nick. Your channel is fantastic. I have a Sony XBR-75X900E that does not power on. No standby light. I am able to measure 3.3V on the standby line, but do not get anything when measuring the 12 volt line to the mainboard. I jumpered the standby, Power On, and Tcon On lines and was able to get 12 Volts to the Tcon line, but still nothing on the 12 volt line to the mainboard. Do you still think it could be the mainboard/emmc chip or do you think it is the rare power supply board failure, and if so, which power supply board. If I'm not wrong, this tv has 2 power supply boards. Any tips on what I should test next to diagnose the problem? Thanks.
This is going to be one where I would say I don't know the answer without being there to do the test myself. Here is the thing, the 75" 900E model may be designed a bit differently and you may need an extra jumper to activate that 12v line. Based on statistics and probability it's your mainboard that is bad and needs to be repaired.
Sorry, we go through too much trouble and spend too much money acquiring good software to give it away for free. It's also not our IP so I can't legally sell it to you. If you have a defective mainboard we would be happy to fix it for you at our flat rate service fee. Once the mainboard is fixed and working you could then remove the eMMC chip off the board and clone the chip.
Remarkable. This exact tv model failed with the boot loop 4 years ago. Got it repaired under an extended warranty which had them replace the main board and flash the firmware. It has been used sparingly since then. It actually hasn't even been turned on in a month, and of course the same issue just popped up again today. This time, no power at all. Sony tv fails every 4-5 years meanswhile I have a samsung and panasonic LCDs going strong after 12-14
You most likely have another mainboard failure on that TV, unfortunately. As for the following statement, I would like to make an amendment if that's okay You had said: "Sony TV fails every 4-5 years mean while I have a Samsung and Panasonic LCDs going strong after 12-14" The amendment is the following: "Older LCD TVs last for 12-14 years whereas newer sets fail within 4-5 years" When people say "they don't make them like they used to" this is very true! The reason is that this is something I have noticed happening with all brands, Samsung and Panasonic included. They all built their sets better in the past, they lasted longer and were more serviceable as well. Now if you tell this to any reps, of any brand they will tell you that newer sets have way more technology and moving parts and thus have a higher chance of something breaking, which in their defense is true. Let me know what you think and if you agree or disagree.
@@NicksTVRepair I definitely agree that a lot of it has to do with how complex TVs are getting today. I had an earlier model Samsung plasma that had a thread on avsforum hundreds of pages long because the TV had a common defect where the screen would sparkle after a year or two. Samsung never admitted any defect. This exact model actually had its base warranty extended from 1 year to 5 years because Sony admitted there was a defect where one of the later firmware updates started causing a lot of tv sets started to fail. I guess it's good that Sony TVs can be repaired fairly easily. But the idea of poassibly having to repair the main board every 4-5 years is insane.
Yeah, this is true. From a customer standpoint, you would expect your appliances to last longer than that. It is weird though because you expect to do yearly maintenance on other things such as your car. Personally, I would prefer to pay more upfront for a higher quality product that would require only certain parts to be replaced every 5 years but have a screen that lasts at least 20 years. Those replacement parts would need to be made available by the manufacturer for at least 10 years after the manufacturing date. I mean if I said that to any large business, they would laugh at me but can you imagine how much less we would be throwing away. This would reduce the amount of metals and chemicals we toss into landfills significantly.
wow this was very helpful have a 55A9G OLED im told the board is no longer available that means the chip is not available correct ? hat to throw a 4 grand set into the garbage over a simple chip end of life issue. fortunately had an extended warranty for a new replacement set but still hate to throw thin into the trash😥
What is the issue you are experiencing with your TV? Chips are typically used across many models, so it's not because a circuit board is no longer available for your specific model TV that the components are all out of stock as well. We are able to get components for many circuit boards that are completely out of stock and have been for years. In fact, a large portion of our repairs are for discontinued circuit boards that are no longer available. I would highly recommend you give me the full list of symptoms you are experiencing with your 55A9G and I will tell you if I can fix it or not.
@@NicksTVRepair unit first started having problems managing HDMI connections. sometimes they wouldn't be recognized. other times streaming devices wouldn't work that were connected to the HDMI ports . i assumed it was either a problem with the streaming devices or the router. the unit is connect via Ethernet. after swapping out cables and resetting the set it worked for a while until connected my apple tv as soon as it defaulted to dolby vision. that's when the screen started to flicker turned the unit off. when attempting to turn it on it when into a restart loop mode . it would power on the sony logo would show then cut itself on then on again over and over. attempted to discharge the unit by unplugging all devices and the tv itself holding the power button down. then attempted what tech support called a hard reset. was able to get the green lite only to have go back into the loop again. asked the tech do you want to come out and see. he said no i've already ordered the parts i know exactly what that is you need a new main board and pwr supply. the pwr supply was was easy it was the OEM board that was continuously on backorder. spoke to my local repair tech he said he could fix as long as it wasnt the Emmc chip because it has proprietary software and the unit may or may not functions without the OEM version along with board he claimed sony does that to protect themselves
Based on the information provided I would tend to believe the defective part is not the eMMC but the main processor chip. The reason is because the eMMC when it fails wouldn't cause the HDMI to stop functioning, however the HDMI processing all occurs on the processor itself. When the processor fails it can also start causing symptoms similar to the eMMC as it stops communicating with it properly which is why you are experiencing the boot loop fault. With that said, of course it is possible that both are failing and both require repairs, and if that's the case then that is something we can take care of for you. Your local tech doesn't have the tools and software for this repair, this is normal, in fact no one does other than us. We are the only ones currently able to perform the repair of this specific mainboard. This is a very niche and advanced repair only a few hundred companies in the world have the tools required to perform it, and almost none of those companies are involved in fixing TVs. You can no longer find new replacement mainboards for this model, they are discontinued and only used / for parts boards are available on eBay or for sale from recycling companies with very low to no quality control. If you are looking for a sure thing, properly tested mainboard, the only way for that to happen would be to send your original for us to fix. nickselectronics.com/products/xbr-55a9g
Good afternoon Nick I ran into a problem with this exact set however I did a factory reset and I do not have the special NFC touch remote that it is asking for. Is there any other way to get a pass this screen I heard maybe a USB mouse would work?
Hello Nicks, I found a donor TV with a broken screen and moved all the components to the TV and the picture did not appear, I updated the software and finally the picture does not appear but a song appeared in the background and with this can you help me download software - maybe that's why it's not updated. I understood that in order to be able to see the display, the motherboard needs to be reprogrammed
If the picture is not appearing it's most likely because the ribbons are not properly inserted. This is the most common reason you don't get picture after replacing a mainboard or swaping out the T-con. Reseat your ribbons, that should do the trick.
Hi NIck, have you seen an issue with the HDR10 not working? I can not use devices with 4K HDR10, such as a fire stick, because the tv will not give me video. I had to change the device to be only 1080. Another issue I'm seeing is that the 3D glasses do not sync. I can see the tv indicated 3D input.
No I have not seen that issue before. What model number is your TV? You may need to replace the mainboard or have it fixed if no replacements are available.
Hi Nick, I watched one of your video regarding pairing a new board thru USB firmware update. I replaced T-Con board for my Sony KD46X8500F TV (No VGH voltage even ribbon cable to the panel were unplug). Then after new T-Con replaced, even my Backlight don't turn ON. The LED flash alternate Green & white. I tried all your method, ten to 20 times, leave it for 6-8hr, didn't work. Rename file name, didn't work. I am wondering, will doing a Factory Reset help? What actually happen when we do a Factory reset? will it pair a new board? Thanks in advance.
Hello Kim, Something isin't right with one of the boards, the software you are using, of the flashdrive. If you tried everything in the video then it should have worked. Recheck all of your connections on all boards, try using a different flashdrive, and make sure its 4gb or larger. Make sure the drive is formated to fat32 and has no other files or folders on the drive. Make sure the file is not inside of a folder or compressed/ziped. Try again maybe using different USB ports. Maybe the USB port you tried is broken or damaged.
Hola Nick. Te escribo desde Argentina. Tengo un Sony igual al del video con el siguiente problema: La TV funciona bien por 5 o 6 horas y luego se apaga destellando el led rojo 6 veces. Hasta ahi todo indicaría problemas es el backlight. Al intentar encenderla nuevamente de inmediato logra encender pero con el backlight destellando por sectores y la imagen con un brillo totalmente excesivo como si estuviera fallando el IC corrector de gama de la pantalla, funciona por unos segundos de esa forma y luego entra en protección nuevamente con 6 destellos. Al desconectarla de la red eléctrica por unas horas vuelve a funcionar normalmente. Agradezco tu ayuda. Saludos
hello I follow your channel and I learn a lot I'm Carlos I live in Brazil I would like if possible to help me with the equipment you use to record an emmc bga memory I saw that you use a recorder I have a recorder but I know how to record the file in the memory you saw that the copy appears in a folder with several files could you record a video on how to read and write correctly these memories in mc nand bga? Thanks
Each device is different, unless you have the same device as we do, then it may not be as usefull as you may think. We have 2 different types of EMMC readers and they have dramactiaclly different steps needed to properly work. Please do not reply to the comment, but instead start a new comment (I don't get reply notifications, only for new comments) and provide the model of your device so I can confirm if it will be more or less the same as ours.
@NicksTVRepair - I have this exact model TV, Most of your Sony TV repairs seem to involve replacing bad chips. Mine has an intermittent main board. In that the TV appears to be dead, but if I tap all over the main board, it will come back to life. My question is- Do these Sony boards ever suffer from heat related cold solder joints and can baking or a heat gun fix my problem? Thanks!
In my experience almost never bad solder joints. 99% of the time it's either an eMMC, HDMI processor, a lightning strike or power surge damages the processor. With that said, it's not impossible, just improbable.
@@NicksTVRepairthanks for your reply! So you're saying that in general Sony TVs don't suffer from the BGA solder problams that Vizios and LGs do? If I do have a damaged chip of any kind, would tapping on the board get it working temporarily? This TV will work for short periods of time (usually until I turn it off) and then to power up the next time I have to do the tapping routine.
Correct Sony TVs don't suffer from the same cracked solder joint faults we see a lot with 4k Vizio sets. LG doesn't really suffer from that issue either. The LG sets from 2009-2015 perhaps did but not the newer 4k sets from the last 5-7 years. Now with that said some of the Sony sets and LG sets do get CPU failures, but cracked joints are not the fault, it's internal failure of the processor in which case they need to be replaced not reflowed. This situation where tapping the CPU allows it to work, I have not seen with any of the Sonys made from 2013 and up. I have fixed over 2000 mainboards and have not seen cracked joints on them. It's 90% of the time failed eMMC, 5% shorted HDMI processor, or 5% failed CPU that needs replacement. Never really seen cracked joints on these before. With that said, it doesn't mean it's impossible. Just very unlikely. If the chip was damaged typically tapping it would not fix it no.
Hi Nick, I have a Sony Bravia KD65XF9005 tv that stopped working. The t-con was changed on it and the red and green light started flashing. I did the software update, now it turns on, the light turns on white and shrinks and is felt on the led on the commands on the remote control and sound when I enter the Menu, the lights are on at the back but no picture. I decided to take the motherboard because there are no specialized people to repair it and I found it on a TV with a broken screen, what do you think?
Fane, It sounds like you don't have proper communication between the new Mainboard and the screen. Most likely this is due to the ribbons not being seated properly. I would recommend having all ribbons from the mainboard to the T-con to be reseated as well as the ribbons going from the T-con to the panel. This should resolve the issue.
Hi Nicks, I found a donor TV with a broken screen and moved all the components to the TV and the picture did not appear, I updated the software and finally the picture does not appear but a song appeared in the background and with this can you help me download the software maybe that's why it's not updated.
I mention that I did a factory reset from the on and low volume buttons and the exact same black screen and with the song in the background, does something have to be rewritten on the motherboard as you show in the clip?
@@fanebriciMy prior statement still stands. It sounds like you don't have proper communication between the new Mainboard and the screen. Most likely this is due to the ribbons not being seated properly. I would recommend having all ribbons from the mainboard to the T-con to be reseated as well as the ribbons going from the T-con to the panel. This should resolve the issue. One step further Replace the ribbons using the ones from the donor TV in case the original are damaged.
i fixed this same tv with no power just by reinstalling firmware from usb, before i put usb there were no power at all no light after placing usb and plug it in outlet i pressed power button and it just goes to installing firmware works great for almost a year
Hey, that's awesome! That doesn't always work, in fact, most of the time it won't but if it does that's great. It usually means that the software you installed is a different version which most likely has no critical data in the bad blocks of the EMMC chip meaning it will allow the chip to work for a small amount of time before failing again. Sometimes it means you can get the set working for another few weeks, or a few months and I have heard of people getting another year out of their set before it eventually failed again. Rarely does it give a long-term solution however because this is not a software fault, as shown in the video the EMMC chip fails on a hardware level. Sometimes the failure is more severe sometimes it is less severe.
@@NicksTVRepair good to know thank you, it just sucks that they put those bad chips that fail easy from logical point if you dont use your smart tv as a smart tv only for watching tv it should last much longer as i think installing apps too many times breaks emmc
@@BUTKO1991 I don't know how to prove it but yes I have that same theory and we have talked about that with my techs that using a fire stick, roku or other external device to access smart apps should help extend the life of the TVs.
Hope you don't mind asking. I live in the UK, so no competition :). I've mentioned that I plan to start fixing EMMC in Sony TVs. Would you recommend any particular programmer for them and software? Thank you :).
Probably the easyJtag Plus since that's the one we use. But its very expensive. You can probably get away with a much cheaper one, however this is the only we we have used so I don't know how good or bad the others are in comparison.
Hi i am trying to connect my ps5 to this which it is detecting but always saying no signal. I have tried on other tv it works well but csnt play on this. Please help
It is possible it is a fault with the TVs mainboard, but it is also possible it's an issue with the signal type. Plug the PS5 into another TV and go to the picture display settings. Make sure to set it to auto. Then try it on the TV again. If you still have issues then I would have you double check to see if other HDMI devices work on the TV. If that is the case then you may want to try a software update or factory reset of the TV or PS5. If other HDMI devices also don't work on the TV then I would recommend you send us your mainbaord for repair as your TV mainboard most likely has failed and will need servicing.
Ps5 is on auto only. The tv detects and shows the playstation is connected but when switching to hdmi it shows no signal. Tried to connect my laptop also but still showed no signal. I also tried factory reset but its still not working. Tried a lot of settings changes also. Plus I stay in India so it will be a little tough to ship the tv abroad.
Hi nick! Love your channel 🎉! I have the same tv, bought the mb and replace it, but i dont get any picture, at the beginning i saw green and orange blinking light, did the usb thing with the software but keeps blinking white and i dont get any picture at all... Please help 😅
The pairing process takes between 30 minutes to 1 hour sometimes. You have to wait for it to stop blinking then it should shut off and turn back on with the picture. If it starts blinking orange and green again then you have to do the pairing a second time. Yes often it needs to be done twice this is normal. If you still have issues I would recommend doing it a third time. If you still have issues then look into reseating your ribbons, and trying again. This should resolve the fault. If it does not then it's entirely possible you received a defective board. If you need more help I would suggest you contact us directly via email or fill out the contact form on our website. Both can be found in the video description.
@@NicksTVRepair thanks for taking the time to answer! Is there a way to make last more the emmc? Of prevent the failure? With the Mobo I have right now with bad emmc, can you fix it? How much would it cost?
I have this tv, and wifi doesent work anymore. It shows my networks, it will simply not connect, it is updated, anyone know of this tv just doesent suppert it anymore, i reset the tv and everything.
My recommendation is to not get that fixed and instead get an amazon firestick that has it's own built in WIFI. The fire sticks have better versions of the apps than any smart TV does, so faster/smoother navigation and more up to date apps.
It’s crazy how many people would just throw out the whole device instead of thinking to try to get it fixed.
Yes it's crazy how many people ask what I do and then respond with "oh that's a thing? I didn't even know you could fix a TV"
With the emmc chip replacement will I lose the native Netflix and Hulu apps?
Yes unfortunately that will always be the case. Fortunately these apps are accessible via dozens of other devices.
@@NicksTVRepairthanks.
there is a solution to reverse engineering key from broken emmc if this data surivive and put to new chip.
@@ukaszjarznicki9049 Yes but the EMMC is damaged beyond that point most of the time. It's less than 50% of the time that it's healthy enough.
very neat work😊❤

Hi Nick. Your channel is fantastic. I have a Sony XBR-75X900E that does not power on. No standby light.

Correct Sony TVs don't suffer from the same cracked solder joint faults we see a lot with 4k Vizio sets. LG doesn't really suffer from that issue either. The LG sets from 2009-2015 perhaps did but not the newer 4k sets from the last 5-7 years. Now with that said some of the Sony sets and LG sets do get CPU failures, but cracked joints are not the fault, it's internal failure of the processor in which case they need to be replaced not reflowed.
This situation where tapping the CPU allows it to work, I have not seen with any of the Sonys made from 2013 and up. I have fixed over 2000 mainboards and have not seen cracked joints on them. It's 90% of the time failed eMMC, 5% shorted HDMI processor, or 5% failed CPU that needs replacement. Never really seen cracked joints on these before. With that said, it doesn't mean it's impossible. Just very unlikely. If the chip was damaged typically tapping it would not fix it no.
Hi Nick, I have a Sony Bravia KD65XF9005 tv that stopped working. The t-con was changed on it and the red and green light started flashing. I did the software update, now it turns on, the light turns on white and shrinks and is felt on the led on the commands on the remote control and sound when I enter the Menu, the lights are on at the back but no picture. I decided to take the motherboard because there are no specialized people to repair it and I found it on a TV with a broken screen, what do you think?
Fane,
It sounds like you don't have proper communication between the new Mainboard and the screen. Most likely this is due to the ribbons not being seated properly. I would recommend having all ribbons from the mainboard to the T-con to be reseated as well as the ribbons going from the T-con to the panel. This should resolve the issue.
Hi Nicks, I found a donor TV with a broken screen and moved all the components to the TV and the picture did not appear, I updated the software and finally the picture does not appear but a song appeared in the background and with this can you help me download the software maybe that's why it's not updated.
I mention that I did a factory reset from the on and low volume buttons and the exact same black screen and with the song in the background, does something have to be rewritten on the motherboard as you show in the clip?
@@fanebriciMy prior statement still stands.

One step further
Replace the ribbons using the ones from the donor TV in case the original are damaged.
i fixed this same tv with no power just by reinstalling firmware from usb, before i put usb there were no power at all no light after placing usb and plug it in outlet i pressed power button and it just goes to installing firmware works great for almost a year
Hey, that's awesome! That doesn't always work, in fact, most of the time it won't but if it does that's great. It usually means that the software you installed is a different version which most likely has no critical data in the bad blocks of the EMMC chip meaning it will allow the chip to work for a small amount of time before failing again. Sometimes it means you can get the set working for another few weeks, or a few months and I have heard of people getting another year out of their set before it eventually failed again. Rarely does it give a long-term solution however because this is not a software fault, as shown in the video the EMMC chip fails on a hardware level. Sometimes the failure is more severe sometimes it is less severe.
@@NicksTVRepair good to know thank you, it just sucks that they put those bad chips that fail easy from logical point if you dont use your smart tv as a smart tv only for watching tv it should last much longer as i think installing apps too many times breaks emmc
@@BUTKO1991 I don't know how to prove it but yes I have that same theory and we have talked about that with my techs that using a fire stick, roku or other external device to access smart apps should help extend the life of the TVs.
Nick im in canada. Can u send me an emmc for the xbr 55x850c mainboard pre programmed? Here theres not a lot of people who do the emmc programming.
Sorry we don't sell emmc chips. We only do board repairs
Hope you don't mind asking. I live in the UK, so no competition :). I've mentioned that I plan to start fixing EMMC in Sony TVs. Would you recommend any particular programmer for them and software? Thank you :).
Probably the easyJtag Plus since that's the one we use. But its very expensive. You can probably get away with a much cheaper one, however this is the only we we have used so I don't know how good or bad the others are in comparison.
@@NicksTVRepair thank you :). Is it come with a software, or any software will do for it?
@@screen-protector It will have it's own system/software
@@NicksTVRepair thank you.
Hi i am trying to connect my ps5 to this which it is detecting but always saying no signal. I have tried on other tv it works well but csnt play on this. Please help
It is possible it is a fault with the TVs mainboard, but it is also possible it's an issue with the signal type. Plug the PS5 into another TV and go to the picture display settings. Make sure to set it to auto. Then try it on the TV again.
If you still have issues then I would have you double check to see if other HDMI devices work on the TV. If that is the case then you may want to try a software update or factory reset of the TV or PS5. If other HDMI devices also don't work on the TV then I would recommend you send us your mainbaord for repair as your TV mainboard most likely has failed and will need servicing.
Ps5 is on auto only. The tv detects and shows the playstation is connected but when switching to hdmi it shows no signal. Tried to connect my laptop also but still showed no signal. I also tried factory reset but its still not working. Tried a lot of settings changes also. Plus I stay in India so it will be a little tough to ship the tv abroad.
Hi nick! Love your channel 🎉!
I have the same tv, bought the mb and replace it, but i dont get any picture, at the beginning i saw green and orange blinking light, did the usb thing with the software but keeps blinking white and i dont get any picture at all...
Please help 😅
The pairing process takes between 30 minutes to 1 hour sometimes. You have to wait for it to stop blinking then it should shut off and turn back on with the picture. If it starts blinking orange and green again then you have to do the pairing a second time.
Yes often it needs to be done twice this is normal.
If you still have issues I would recommend doing it a third time. If you still have issues then look into reseating your ribbons, and trying again.
This should resolve the fault.
If it does not then it's entirely possible you received a defective board.
If you need more help I would suggest you contact us directly via email or fill out the contact form on our website. Both can be found in the video description.
@@NicksTVRepair thanks for taking the time to answer!
Is there a way to make last more the emmc? Of prevent the failure?
With the Mobo I have right now with bad emmc, can you fix it? How much would it cost?
I need emmc fimware sir.
please help me
That may not be something we can assist with.
Hi friend can send me the emmc firmware?
Sorry we don't do that right now.
I have a Sony xbr-55x850c blinking led 6 times
6 blinks means LED failure. You will need to replace your LED strips to fix that fault.
I want kd55x9500g emmc dump file please send me
Sorry we don't have any software for none USA models
I have this tv, and wifi doesent work anymore. It shows my networks, it will simply not connect, it is updated, anyone know of this tv just doesent suppert it anymore, i reset the tv and everything.
My recommendation is to not get that fixed and instead get an amazon firestick that has it's own built in WIFI. The fire sticks have better versions of the apps than any smart TV does, so faster/smoother navigation and more up to date apps.
