You need to change that supercapacitor if you haven't done so already it is corroding your motherboard and your printer will be dead in 3-6 months if you don't
Dude!!! You are the fricking MAN. Just did the procedure you described at the 3:50 mark and it worked like a champ. Thanks for taking the time to make this video.
Thanks! The fix worked for my MFC-L2720DW. The hardest part was re-installing the plastic side panel. I admit that my soldering was kind of bad but I tested with a DVM before re-assembling.
WOW! Mr. Jones' turn-on sequence worked for me immediately. Without his help, I would have had to buy a new printer--and of course the outage came at a time I urgently needed print-outs.
I was sitting in front of my L2700DN which also didnt want to switch on and luckily found your Video. I was instantly able to get it back to work with the reset procedure. Thanks man, you saved me a few hundred bugs for a new printer.
You can't imagine, i'm so thankful for this video. I just bought a new toner and the very next day i turned of the printer and it didn't want to start anymore.
Thank you so much. We had a bad storm with lightening that struck very close. My computer router got fried and my printer would not turn back on. It was due to your video that I now have a working printer. Your reset technique worked great. Thanks again.
MFC-9130CW has 2 capacitors! Good thing I ordered an extra. 1 extra screw to remove from cover, and a metal shield over the mother board. Even though a different unit it was helpful to see your approach to removing the cover. I love how removing covers sounds like you're breaking them. Sometimes you are.
@@nathanblades3395 you have to change the super capacitor otherwise in 3-6 month's it won't turn on at all. Not being able to turn on is a sign the capacitor is starting to leak and corroded the board

Hi Terry, I'm from US, California. we own a Brother HL-L2380DW, bought new several years ago. It's been lightly used. when we don't use it, we unplug it from wall. Several months ago, it refused to turn on. After looking at some of on-line fixes (before seeing yours), I was able to turn it on after a few tries (press and hold the turn on/off button, and plug the power). But recently, the "trick" no longer works even after many tries. the screen would keep flashing but doesn't turn on. I researched on-line again for the fixes, and found your repair UA-cams. I opened the side cover, checked the board, and found that the board looks the same as your UA-cam model. So I went ahead ordered your Supercapacitor (which took more than 2 weeks to arrive!). I replaced the capacitor, but to my surprise, now the screen is not even flashing, and there is no sign of life of the printer even I tried the "reset". I did everything very carefully, and I think I am pretty good on electronics repairs and using soldering tool (mine is 40W I believe). So this is pretty much a mystery to me... I then opened the cover on the other side where the power board is located. The power board looks similar to the one you demonstrated on the UA-cam, but not exactly the same. It does have 2 fuses which are all good after checking, and there is no sign of anything turned, or mold. I measured the voltages at the connector (8-pin) the 2x 24V are presents (24.5V) ... what could be wrong according to your experience? I just don't like to throw away things like this which are well engineered and lightly used (we might have just printed less than 500 pages!). Thanks in advance for your advice!
Yes unfortunately the window of opportunity to repair your printer had passed. As you have now learnt you must replace the supercapacitor when it reaches the "having to power it on whilst holding the button down stage". If you don't replace the supercapacitor and you keep turning it on using the power button method eventually the main board gets wrecked completely. If you had replaced the supercapacitor at the very moment the problem began your printer would still be functioning today and would continue to work for the next 5 years. It is also important that the supercapacitor gets replaced from the topside and not pulling the motherboard out flipping it over and replacing it from the bottom side just because you want to do a nice clean job, the boards are multilayered not two sided and the risk of damaging internal board layers is very high. The moment the problem begins the supercapacitor must be replaced or with in 3 months you'll have to buy a new printer
Make sure you change the supercapacitor asap! failed capacitors leak their alkaline contents and corrode the main board. Then the printer is Truly dead.
I ran into this problem after having turned off my printer during vacation 😱 and with great disbelief and a heavily raised eyebrow I watched your video, read the description of the video and a bit of the comment section before trying it. Holy moly: it works 🙃! Feels like a feature and not a bug. Infinite thanks! 😇
Hi Terry, i did the repair and it works, now my computer can't communicate to the printer. Screen says receiving data. FIXED! I did a firm ware update and restarted computer, all good!
Great video, any chance the power supply video can be shown? This trick did not work so Im sure its the power supply as you mentioned. If its the fuse im wondering if I can just go up a knotch that way it doesnt blow again. thank you.
Do the test three times in a row just to be sure. In a lot of the cases I see now due to the age of the printer it is not a dead power supply causing it not turn on. The supercapacitor can leak it's alkaline contents on the main board which corrodes it and kills the main board in the process
Hello Terry, I was wonder in the case that it doesn't turn on with the method shown you had said it could be the power supply possibly being shot. Is there a way to replace the power supply on a MFCL2710DW model? Thankyou
Thank you for the video. My Brother MFC-L2700DW would not turn on. Your 4 steps got it back up and running ... so, it does appear to be a capacitor issue. I've saved the links to this video and your website if I decide to repair it. I was getting ready to buy a faster printer (not an AIO) with a larger tray even though I was sick over the money I had just spent for a new drum and toner.
Hello I'm writing from Rome. My quite new Brother printer is the basic L2375DW which had replaced a similar but older very sturdy model. Well, the new one konked out suddenly. The printer repair shop told me it was capacitor failure as its outflow current was half the normal current) (??). Anyway I tried the reset system several times but it didn't work. As you said at the very beginning , if the reset doesn't work then it's not the capacitor and not to try it out. Quite confused now. Does this mean the new machine is dead or is there another maybe complicated reason? Thanks so much, hope you can answer me on the what to do now question. I had also watched your soldering video, very interesting and very detailed. Thanks so much, Kate
I’m sorry for the inconvenience. I really appreciate this. The printer turns on the problem that I’m having is the temporary thing that I was doing turning off the printer waiting a couple of minutes and then plugging the extension at the same time. That part is no longer working. I’m able to print things but I’m unable to use the Bluetooth. It’s no longer letting me send Bluetooth with my printer. Don’t know if this is what you mean but I appreciate you thank you.
my dcp-L2520DWR printer shows flashing squares on the display every 3 seconds when the power cable is turned on, what could have broken? I did not find a super capacitor on the main board
I have the L2740. When I turn it on, the screen turns on but it's blank (no logo), none of the buttons light up. The screen then turns off and I can hear the printer's initiating sequence (motors, fans start moving). Then a "click" noise happens and the printer shuts off. I tried to do the reset like you showed, but the machine still behaves the same. Would appreciate to get your take Mr. Jones!
Thank you.... Thank you very much. I had a paper jam, turned the printer off and it would turn back on. It would have been ok, but I was a work and the next shift was coming on. Again Thank you.
You need to change the supercapacitor on the motherboard. The fact that you couldn't turn your printer on is a sign that the super capacitor has failed and is about to leak. You have about 3 months before the printer is dead completely
I have a dcp 8110 that will not turn on after initially it is used. You have to leave it for 20 minutes before you can get it to turn on. Can you help me thanks Jon
@@TerryJonesPrinterRepairs How soon will the repair needs to be done before it fails again completely? and I wasn't able to find your other video which shows how to replace the capacitor. Thanks again.
Thank you for your great advice! I have a quick question. I turned my printer off a few days ago by holding the power button down until it shut off. I don't think I ever did that before. Then I couldn't get it to start back up until I reset it per your procedure. But now it stays on, and even if I unplug it and plug back in, it turns on like normal without having to perform the reset procedure. Do you think I still need to replace the super cap?
Probably not but you need to take the side cover off and look at the area around the super capacitor on the main board to see if it's starting to corrode.
Okay, I pulled that cover off again to look around the super capacitor, and saw no corrosion at all. Man that cover is a bugger to get back on! But I got it back on and everything is back up and running well again. Thank you for all help!
I have a MFC-L2720DW, and a similar problem. After reading the comments here I've decided that I should look into the process of updating the firmware. After a power outage my printer is cycling on over and over. The scanner head moves a few steps and then the printer resets and starts all over again. I'm stuck in that loop. The scanner head eventually makes it to the end and can go no further so the drive belt just clicks over the cogs and then the printer resets again. I opened it up and reversed the belt to return the scanner head to home and the same process repeats - scanner moving a few steps with each automatic reset until it hits the end of the track and just clicks. I have tried the reset but I can't seem to interrupt the power cycling loop. I'll try to replace the super-cap if you think that will solve it.
Unfortunately you have left it too late you needed to change your supercapacitor a few months ago. You will find your motherboard will have a section that is corroded from the alkaline salts inside the supercapacitor leaking out this is why it keeps turning itself off and on rebooting endlessly. You need to replace your motherboard
@Terry Jones Printer Repairs thank you for the diagnosis. Is the motherboard an easy worthwhile repair for someone without much soldering skill? I think we might just cut our losses and get a new laser printer instead of pouring more time into this one. It is 6 or 7 years old and has seen lots of use. Something robust and more basic with wireless printing if you have any recommendations. Fax not required, could drop photocopying and scanning if that makes it less likely to fail. We've liked Brother over the last 15 or so years.
Replaced Super Capacitor & it absolutely fixed the power-switch issue!! However, I'm getting an ADF cover open error message that I can't clear.... paper isn't jammed or stuck in ADF. Any suggestions? Thanks
Thanks for replying. A connector came loose after transporting the Brother MFC-L2700DW home from the workshop. Reconnected it & everything works great. Thanks for saving me the $250 for a new printer!! Please keep posting for your community followers!
I found I was unable to solder to the remnants of the supercap. I un-soldered everything and soldered my new supercap onto the pads of the motherboard. It worked fine. + is up[ in case you were wondering.
See the message from the guy above who let it go too late, you have to change the supercapacitor if you want a printer that works in 3 months, being unable to turn the printer on is a sign the capacitor is starting to leak and is about to corrode your motherboard.
Also, looking for continuation of this UA-cam because it only goes up to removing the capacitor, but not soldering new one in. I’ll look around for that
Hi, I came across your video. I am having problems with my printer. What part of the printer is damage at this point. The temporary solution of turning off and then turning on, has been working for sometime, but it’s no longer working. What The name of the part that I need to purchase to fix this problem
Too late Buddy you now need a new printer. As explained in all the videos when you cannot turn your printer on by using the power button the supercapacitor has failed and is leaking it's alkaline contents onto the motherboard. Using the reset method does get it to turn on but if you do not replace the supercapacitor immediately your motherboard gets damaged from corrosion.
Annoying shits are a plague on us all. Thank you very much for this tutorial, which reinforces my suspicion that getting necessary home gadgets to work involves a form of magic not based in any logico-deductive paradigm. Notwithstanding that, I’m most grateful. Cheers from El Lay
Have an MFC-2720DW. The unit does turn on and the brother logo appears. Fan and various rollers etc. will go through the initial start up procedure. Then the screen will remain white with Brother logo for various lengths of time before you hear a click and it will start the entire process over again. Seems like it will continue to do this forever, it has randomly completed start up during this cycling and started working for me twice since the problem began. When it loses power or there is a flicker it returns to this state and will not complete power up.
Very informitive video thank you so much! I have the same printer as shown in the video (Brother MFC-L2740DW). However my printer receives power but the screen blinks white. Other computers do not recognize this as a printer anymore. Will your method work for my issue or is my printer a brick. It would be great to hear what you have to say. Thank you.
No you have a blow-up main board or scanner replacing the capacitor will not fix your problem. Unplug all cables from the motherboard accept the power supply and the screen cable to isolate if it's an external part other than the main board that has failed.
Thanks for the video Terry. My MFC 2700dw was unplugged for a week and now only the buttons below the LCD stay on meanwhile the LCD flashes without staying on. How do I fix this printer to stay on?
The clock is ticking you need to change the dead supercapacitor, that dead supercapacitor starts to leak alkaline salts when it fails and corrodes the bottom right corner of the motherboard.
I am having a similar issue in which my printer model MFC-L8610 CDW will not power on but the power light it solid green. Any ideas? I tried your reset procedure but failed.
You need to plug a usb cable direct from your printer to your computer and run the firmware update tool and update the firmware. The printer has been turned off in the middle of a firmware update.
Hi Terry, I have a MFC-J475DW that stopped turning on after I unplugged it and plugged it back in. When I did the reset procedure, the lcd screen quickly flashed white, then turned off. Since it still turned on, I went ahead and replaced the supercapacitor; however, it is still behaving the same way. Any ideas what's going on, and what I can do to fix it? Thank you!
Did you install the new super cap the right way around? Some replacement supercaps are acually labelled the wrong way around. + is - All super caps have the same physical layout simply install the new one "looking the same way" and ignor the + and - symbols. An entire batch I received from china recently was back to front.
If it's an old wifi router your using you need to change the network settings in the printer to a static IP address and communicate with the printer by IP address. The down side of this is any Apple products will have trouble communicating with the printer. If your router is new leave the printer network settings set to auto IP and communicate by Node Name. If you are using wifi boosters or repeaters on your network you must connect the printer to your primary wifi router by either wifi or cable connection.
Hey bro I have got MFC-L2713DW I have tried everything it still doesn't work. I think the problem is not in the capacitor. It doesn't turn on with your method. Can you please help me to fix it. Thanks
I am dealing with something similar with my Brother MFC-9970CDW. When you turn on the machine the screen with brother logo comes on for a few seconds and the printer makes all sorts of noises as its warming up etc but then it dies, the fax/scan/copy buttons stay lit though (for some reason the Fax button is dimmer than the other two). The machine doesnt have an actual power button on the front, just a power switch on the side. Before I commit to buying a PCB is there a way to do a power reset on these machines to see if the problem is actually the PCB if not something else? Any help would be greatly appreciated, thank you.
plug a usb cable from your computer directly to the printer then download the firmware update tool from brothers website and update the printers firmware.
@@TerryJonesPrinterRepairs Thank you, that didnt do anything :/. I have disassembled everything and right now have the PCB and power supply board in front of me lol, not sure what to do at this point, I can invest $80 and get replacement boards but that would require a month long wait. Any thing I can test to see if its faulty and may be replace it? The capacitors on the power supply board are covered on the solder side with a plate that holds some components in place. The plates and the components are soldered onto the board, not sure if it'd be worth trying to take everything off as replacement board is $30ish.
Hi Terry. I confirmed the issue was the capacitor with your test sequence and ordered one. During that test I noticed during that the printer had stopped connecting to the WiFi network. Replacing the capacitor fixed the power issue but WiFi still doesn't connect (not able to connect to the WiFi network although it does see some of them; maybe receive is working but transmit is not???) Not really a big problem as I was able to hard wire to an ethernet port on my router. However knowing that the printer is now impaired should I ever need to move it to a location away from a router ... does it seem to be a frequent occurrence that the capacitor blowing fries the WiFi card? Is there a replacement part for the WiFi card - I noticed a daughter board plugged in to the main processor board and thought that may be a WiFi card. I have the MFC-L2740DW product. At any rate, thank you so much for saving me the money to replace the printer right out. It is much appreciated.
@@TerryJonesPrinterRepairs Hi Terry - Thank You for the reply. Sorry I am late responding as I don't sign in much. I am in the US. Everything has been working fine using the ethernet cable. I just asked the original question to see if you had seen the capacitor issue take out anything else with it. I am happy as is and the printer is still working great. Have a great week!
Great info, but the video cuts out at 15 minutes for me. Do you have the rest of the video somewhere? Also, you mention creating a video testing a regular capacitor, but I can’t find it on your channel. Did you ever try that?
According to your video I have a bad PSU on my 2750DW. I have been unable to find a solution to this problem on youtube. Have you made a video about this or do you know a video that is at least partially applicable to this model?
I have a DCP-L2550DW which was unplugged and now refuses to turn on. There were no issues with it before this happened. I tried the unplug/plug/hold-power-button sequence and the machine is unresponsive. Brother refuses to honor the warranty because I do not have a receipt (bought it new from a private party). Should I replace both the capacitor and the PSU?
@@TerryJonesPrinterRepairs The local authorized dealer was nice enough to order and sell a power board to me. Just installed it and it powered on immediately. Should I bother repairing the old one? The entire board cost $35. The website you list has the capacitor for $28. Seems like a better deal to replace the entire shebang
New subscriber watching from Al Khafji Saudi Arabia. Sir i have MFC L8690dcw my problem is NO DISPLAY but there is power indicator light. Any help im very appreciated thank you...
Interesting. Unfortunately my 2730DW isn't quite doing that. When I plug it in, I get the green LED, but nothing else. No sounds, no chime, no display. Holding the power button while plugging in doesn't do anything. It is interesting when I plug in USB, the Brother software recognizes it as a 2730DW, but I can't firmware update it - the tool is useless. It recognizes the printer and when I click next/continue it looks like it's doing something, it gets to 100% and I have option to continue to update another unit or click done or finish, at which point the update tool just closes. No effect on the printer itself - as nothing is on the LCD. When I connect it to my LAN via ethernet, nothing happens, probably because the ethernet is not enabled. Not sure how I can get the screen working or even if I can be sure what the problem even is. Just green light on the power when plugged in. When I hold the power, it doesn't turn off the printer or do anything . None of the other buttons are responsive, likely because the screen has nothing on it. Any ideas would be welcome
What SUPER CAPACITOR do I buy? There is a 1x, 2x, and 3x. It states that one must buy 2 to get fast delivery. Does 2x mean two capacitors or two times power as the 1x? Thank you.
I had turned off the printer in preparation for power outages during the hurricane here in Florida. When power was restored and I turned the printer on; nothing happened.
The discharge on the capacitor trick by holding the power button down and then plugging back in while holding the power button worked.

Does this mean the new machine is dead or is there another maybe complicated reason? Thanks so much, hope you can answer me on the what to do now question. I had also watched your soldering video, very interesting and very detailed. Thanks so much, Kate
OMG! Thanks! My printer just turned on! Thanks so much.
You need to change the supercapacitor. Failure to replace it will mean a completely dead printer in 6 months
I’m sorry for the inconvenience. I really appreciate this. The printer turns on the problem that I’m having is the temporary thing that I was doing turning off the printer waiting a couple of minutes and then plugging the extension at the same time. That part is no longer working. I’m able to print things but I’m unable to use the Bluetooth. It’s no longer letting me send Bluetooth with my printer. Don’t know if this is what you mean but I appreciate you thank you.
Thank you so much! I turned on the printer by watching your video!
Thank you Sir. my printer worked rightaway after your trick
The repair worked perfectly, thanks a lot! Did you get around to trying to replace the supercap with a regular capacitor?
THANK YOU for saving me a load of time and potentially money!!
my dcp-L2520DWR printer shows flashing squares on the display every 3 seconds when the power cable is turned on, what could have broken? I did not find a super capacitor on the main board
THANK YOU SO MUCH , SO GOOD OF YOU TO SHARE THIS. IT WORKS!!!
I have the L2740. When I turn it on, the screen turns on but it's blank (no logo), none of the buttons light up. The screen then turns off and I can hear the printer's initiating sequence (motors, fans start moving). Then a "click" noise happens and the printer shuts off. I tried to do the reset like you showed, but the machine still behaves the same. Would appreciate to get your take Mr. Jones!
Thank you.... Thank you very much. I had a paper jam, turned the printer off and it would turn back on. It would have been ok, but I was a work and the next shift was coming on. Again Thank you.
You need to change the supercapacitor on the motherboard. The fact that you couldn't turn your printer on is a sign that the super capacitor has failed and is about to leak. You have about 3 months before the printer is dead completely
@TerryJonesPrinterRepairs Thank you I will let management know. 👍🏽
I have a dcp 8110 that will not turn on after initially it is used. You have to leave it for 20 minutes before you can get it to turn on. Can you help me thanks Jon
Your solution resolved my "power on" problem.
Do I still need to replace the capacitor?
Thanks a bunch.
yes, it has failed and will be starting to leak its alkaline contents which corrode the motherboard.
@@TerryJonesPrinterRepairs How soon will the repair needs to be done before it fails again completely?
and I wasn't able to find your other video which shows how to replace the capacitor.
Thanks again.

Thank you for your great advice! I have a quick question. I turned my printer off a few days ago by holding the power button down until it shut off. I don't think I ever did that before. Then I couldn't get it to start back up until I reset it per your procedure. But now it stays on, and even if I unplug it and plug back in, it turns on like normal without having to perform the reset procedure. Do you think I still need to replace the super cap?
Probably not but you need to take the side cover off and look at the area around the super capacitor on the main board to see if it's starting to corrode.
Okay, I pulled that cover off again to look around the super capacitor, and saw no corrosion at all. Man that cover is a bugger to get back on! But I got it back on and everything is back up and running well again. Thank you for all help!
Ok, I ordered the part from you. Do you also have a video for a layman on how you solder it back in? Thank you

I have a MFC-L2720DW, and a similar problem. After reading the comments here I've decided that I should look into the process of updating the firmware. After a power outage my printer is cycling on over and over. The scanner head moves a few steps and then the printer resets and starts all over again. I'm stuck in that loop. The scanner head eventually makes it to the end and can go no further so the drive belt just clicks over the cogs and then the printer resets again. I opened it up and reversed the belt to return the scanner head to home and the same process repeats - scanner moving a few steps with each automatic reset until it hits the end of the track and just clicks. I have tried the reset but I can't seem to interrupt the power cycling loop. I'll try to replace the super-cap if you think that will solve it.
Unfortunately you have left it too late you needed to change your supercapacitor a few months ago. You will find your motherboard will have a section that is corroded from the alkaline salts inside the supercapacitor leaking out this is why it keeps turning itself off and on rebooting endlessly. You need to replace your motherboard
@Terry Jones Printer Repairs thank you for the diagnosis. Is the motherboard an easy worthwhile repair for someone without much soldering skill? I think we might just cut our losses and get a new laser printer instead of pouring more time into this one. It is 6 or 7 years old and has seen lots of use. Something robust and more basic with wireless printing if you have any recommendations. Fax not required, could drop photocopying and scanning if that makes it less likely to fail. We've liked Brother over the last 15 or so years.
Terry, this is very helpful. Thanks. Do you know if this would also apply to the MFC-7440N ?
Thank you! Life saver!
Replaced Super Capacitor & it absolutely fixed the power-switch issue!! However, I'm getting an ADF cover open error message that I can't clear.... paper isn't jammed or stuck in ADF. Any suggestions? Thanks
What model printer
Thanks for replying. A connector came loose after transporting the Brother MFC-L2700DW home from the workshop. Reconnected it & everything works great. Thanks for saving me the $250 for a new printer!! Please keep posting for your community followers!
I found I was unable to solder to the remnants of the supercap. I un-soldered everything and soldered my new supercap onto the pads of the motherboard. It worked fine. + is up[ in case you were wondering.
thank you so much, it works!! i really thought my printer was destroyed.
My god this is a live saver, thanks a lot for your video!
Thank you! Did the reset and it works..all that it needed
See the message from the guy above who let it go too late, you have to change the supercapacitor if you want a printer that works in 3 months, being unable to turn the printer on is a sign the capacitor is starting to leak and is about to corrode your motherboard.
Also, looking for continuation of this UA-cam because it only goes up to removing the capacitor, but not soldering new one in. I’ll look around for that

Hi, I came across your video. I am having problems with my printer. What part of the printer is damage at this point. The temporary solution of turning off and then turning on, has been working for sometime, but it’s no longer working. What The name of the part that I need to purchase to fix this problem
Too late Buddy you now need a new printer. As explained in all the videos when you cannot turn your printer on by using the power button the supercapacitor has failed and is leaking it's alkaline contents onto the motherboard. Using the reset method does get it to turn on but if you do not replace the supercapacitor immediately your motherboard gets damaged from corrosion.
Annoying shits are a plague on us all. Thank you very much for this tutorial, which reinforces my suspicion that getting necessary home gadgets to work involves a form of magic not based in any logico-deductive paradigm. Notwithstanding that, I’m most grateful. Cheers from El Lay
Have an MFC-2720DW. The unit does turn on and the brother logo appears. Fan and various rollers etc. will go through the initial start up procedure. Then the screen will remain white with Brother logo for various lengths of time before you hear a click and it will start the entire process over again. Seems like it will continue to do this forever, it has randomly completed start up during this cycling and started working for me twice since the problem began. When it loses power or there is a flicker it returns to this state and will not complete power up.
Plug in a USB cable directly from the printer to your laptop and update the printers firmware
Very informitive video thank you so much! I have the same printer as shown in the video (Brother MFC-L2740DW). However my printer receives power but the screen blinks white. Other computers do not recognize this as a printer anymore. Will your method work for my issue or is my printer a brick. It would be great to hear what you have to say. Thank you.
No you have a blow-up main board or scanner replacing the capacitor will not fix your problem. Unplug all cables from the motherboard accept the power supply and the screen cable to isolate if it's an external part other than the main board that has failed.
Thanks for the video Terry. My MFC 2700dw was unplugged for a week and now only the buttons below the LCD stay on meanwhile the LCD flashes without staying on. How do I fix this printer to stay on?
perform the reset procedure in the video
Yes your little Hack did work ; it came on ; thanks for your help
clocks ticking you need to change that super cap as your failed one will be leaking and corroding the board
I just had this problem. Thanks my brother.❤
The clock is ticking you need to change the supercapacitor
So you think that’s going to happen again?
How do I fix this problem? It’s a good printer. This is the first time this happens to me.

I just was thinking to buy a new printer. you saved me a printer
The clock is ticking you need to change the dead supercapacitor, that dead supercapacitor starts to leak alkaline salts when it fails and corrodes the bottom right corner of the motherboard.
I am having a similar issue in which my printer model MFC-L8610 CDW will not power on but the power light it solid green. Any ideas? I tried your reset procedure but failed.
You need to plug a usb cable direct from your printer to your computer and run the firmware update tool and update the firmware. The printer has been turned off in the middle of a firmware update.
Hi Terry, I have a MFC-J475DW that stopped turning on after I unplugged it and plugged it back in. When I did the reset procedure, the lcd screen quickly flashed white, then turned off. Since it still turned on, I went ahead and replaced the supercapacitor; however, it is still behaving the same way.
Any ideas what's going on, and what I can do to fix it?
Thank you!
Did you install the new super cap the right way around? Some replacement supercaps are acually labelled the wrong way around. + is - All super caps have the same physical layout simply install the new one "looking the same way" and ignor the + and - symbols. An entire batch I received from china recently was back to front.
That worked. Thanks. Any idea how to get my L2700DW from dropping off the network?
If it's an old wifi router your using you need to change the network settings in the printer to a static IP address and communicate with the printer by IP address. The down side of this is any Apple products will have trouble communicating with the printer. If your router is new leave the printer network settings set to auto IP and communicate by Node Name. If you are using wifi boosters or repeaters on your network you must connect the printer to your primary wifi router by either wifi or cable connection.
My MFC-J6510DW won't light up/turn on. Is there a solution? Thanks
Yes buy new printer that printer is 20 years old you've had it long enough
Hey bro I have got MFC-L2713DW I have tried everything it still doesn't work. I think the problem is not in the capacitor. It doesn't turn on with your method. Can you please help me to fix it. Thanks
Thank you so much, it worked just fine for me !!!!
I am dealing with something similar with my Brother MFC-9970CDW. When you turn on the machine the screen with brother logo comes on for a few seconds and the printer makes all sorts of noises as its warming up etc but then it dies, the fax/scan/copy buttons stay lit though (for some reason the Fax button is dimmer than the other two). The machine doesnt have an actual power button on the front, just a power switch on the side. Before I commit to buying a PCB is there a way to do a power reset on these machines to see if the problem is actually the PCB if not something else? Any help would be greatly appreciated, thank you.
plug a usb cable from your computer directly to the printer then download the firmware update tool from brothers website and update the printers firmware.
@@TerryJonesPrinterRepairs Thank you, that didnt do anything :/. I have disassembled everything and right now have the PCB and power supply board in front of me lol, not sure what to do at this point, I can invest $80 and get replacement boards but that would require a month long wait. Any thing I can test to see if its faulty and may be replace it? The capacitors on the power supply board are covered on the solder side with a plate that holds some components in place. The plates and the components are soldered onto the board, not sure if it'd be worth trying to take everything off as replacement board is $30ish.
Worked perfectly. Thank you so much!
fantastic working solution
Seriously thank you so much!
Hi Terry. I confirmed the issue was the capacitor with your test sequence and ordered one. During that test I noticed during that the printer had stopped connecting to the WiFi network.
Replacing the capacitor fixed the power issue but WiFi still doesn't connect (not able to connect to the WiFi network although it does see some of them; maybe receive is working but transmit is not???)
Not really a big problem as I was able to hard wire to an ethernet port on my router. However knowing that the printer is now impaired should I ever need to move it to a location away from a router ... does it seem to be a frequent occurrence that the capacitor blowing fries the WiFi card? Is there a replacement part for the WiFi card - I noticed a daughter board plugged in to the main processor board and thought that may be a WiFi card. I have the MFC-L2740DW product.
At any rate, thank you so much for saving me the money to replace the printer right out. It is much appreciated.
Are you based in Australia and do you have a Telstra WIFI Modem Router by chance?
@@TerryJonesPrinterRepairs Hi Terry - Thank You for the reply. Sorry I am late responding as I don't sign in much. I am in the US. Everything has been working fine using the ethernet cable. I just asked the original question to see if you had seen the capacitor issue take out anything else with it. I am happy as is and the printer is still working great. Have a great week!

According to your video I have a bad PSU on my 2750DW. I have been unable to find a solution to this problem on youtube. Have you made a video about this or do you know a video that is at least partially applicable to this model?
I have a DCP-L2550DW which was unplugged and now refuses to turn on. There were no issues with it before this happened. I tried the unplug/plug/hold-power-button sequence and the machine is unresponsive. Brother refuses to honor the warranty because I do not have a receipt (bought it new from a private party). Should I replace both the capacitor and the PSU?
Just the power supply
@@TerryJonesPrinterRepairs The local authorized dealer was nice enough to order and sell a power board to me. Just installed it and it powered on immediately. Should I bother repairing the old one? The entire board cost $35. The website you list has the capacitor for $28. Seems like a better deal to replace the entire shebang

Great Video! Now just need to change the capacitor!
I visited your website, but can't find the parts for the model #: mfc-L2740. Am I missing something?
I only have some of the parts I sell listed, What do you require?
Interesting. Unfortunately my 2730DW isn't quite doing that. When I plug it in, I get the green LED, but nothing else. No sounds, no chime, no display. Holding the power button while plugging in doesn't do anything. It is interesting when I plug in USB, the Brother software recognizes it as a 2730DW, but I can't firmware update it - the tool is useless. It recognizes the printer and when I click next/continue it looks like it's doing something, it gets to 100% and I have option to continue to update another unit or click done or finish, at which point the update tool just closes. No effect on the printer itself - as nothing is on the LCD. When I connect it to my LAN via ethernet, nothing happens, probably because the ethernet is not enabled. Not sure how I can get the screen working or even if I can be sure what the problem even is. Just green light on the power when plugged in. When I hold the power, it doesn't turn off the printer or do anything . None of the other buttons are responsive, likely because the screen has nothing on it. Any ideas would be welcome
