RUclips have demonetized my channel, all because of the Jimi Hendrix video I improved and uploaded that went viral AND CAN BE FOUND HERE ruclips.net/video/liG349SoF_U/видео.html . I no longer earn anything from my printer repair videos while they still profit from them. Support for the channel can be made at the link in the video description.
@@denisdb725 Having trouble interpreting your comment denis, Are you saying your glad?
@@denisdb725 Please explain Denis, why should they have demonitized my RUclips channel from the very start?
@@denisdb725 So I see Denis, you clearly have a lot of time to whinge and complain and wish ill of other people yet you also expect at the same time people to give you everything to you on a platter. Yes I am very rude to lazy people who expect me to offer up all of the knowledge in my head for free so that you can then go give your money to someone else benefiting them and their family. This was clearly your intent when you asked "what are the values of the supercaps" rather than clicking on the link to my website and buying it there. Do you think that this is fair that you come to my RUclips channel get everything you need to solve your problem then give your money to someone else with them doing absolutely nothing to get your money? I don't think that is very fair at all and shame on you for trying to take advantage of me then when not getting what you want verbally abusing me. Its a very nice home you live in as i've seen from your own YT videos much nicer than mine SO YOU CLEARLY ARE NOT POOR and I bet you own more than 1 property.
The power on trick helped me! Replaced toner then printer would not power on! Tried everything to no avail! Then watched the first part of this video and did the plug in while holding down power button! It came on! Thanks!
Your printer is not fixed you need to change the supercapacitor . You old supercapacitor will be leaking and corroding the board.
Absolutely brilliant, thank you!! I tried the unplug / press power for ten secs, release, press and hold power switch and connect power cable and it worked!! You’re a lifesaver!
Your printer is still broken, you need to replace the failed supercapacitor before it becomes permanent off.
Legend, would never have guessed this fix
Did work for my Brother DCP 9022CDW. It has two capacitors at the same area. I only did replace the one at the back! THANK YOU!
Just ordered. Thank you very much. I am still in shock at how Brother is not having a blanket recall... I am glad I found your channel. Thanks again mate!!
It is reasonable Wear and tear not a defect.
Worked First try with this method! Thank you so much for making this. Sometime seeing work from start to finish is better than repair cut aways
OMG! I fixed it by following your steps, it is absolutely Amazing! I can't explain the operating principle.
Helped out a bunch getting my daughter's homework printed in time. Thanks.
...aaaand it works again. Many thanks for putting this video up. I suspect my previous brother printer suffered the same issue, but I didn't find the video in time for that one. So it goes...
Thank you. I was able to turn on again. Great help I appreciate it !
Thank you!!!! This turned my MFC-L2740DW back on!! I only had to watch 3:43min of the video!
The clock is ticking for you, you need to replace the supercapacitor on your printers mainboard as it has started to leak. If you don't replace it you will need to buy a new motherboard or new printer in the next 3-6 months
This is the video that relates to your printer ruclips.net/video/OgkHv1c01tQ/видео.html
Where can the super capacitor be purchased? I’m in the US
Thank you !!! Took multiple tries but eventually the power came back on !😃
You're a genius mate. I had the same issue and did the steps. Lo and Behold, its powering on!!
You need to replace your supercapacitor. The one currently on your circuit board will be starting to leak it's alkaline guts which then corrode the motherboard.
The power button trick worked like a sharm on MFC-L2700DW. Thank you good sir. I should replace that supercap though.
Thank you Terry. A bloody legendary effort. Appreciated very much...😀😀
yeh I have a MFC-L3750CDW and this worked, thank you so much!!
Thank you, it was very helpful 😊
You are the best ! Thanks a lot! I need my printer seriously and your video save me 🥰🎉🎉🎉🎉🥳🥳🥳
Thanks for that! Life savior
Appreciate the troubleshooting guide
Thank you so much for your video, it fixes my issue.
You sir are a legend !!! Was able to get it going again
fantastic mate! reset worked a treat for me :) :) subbed and liked as a thank you.
lifesaver.thank you ❤❤❤
You just save me £400, Thank You big time!!!!

thanks for posting
Thank you sooo much for this - it worked!!!
Your are a the best bro
Thank you so much
Hi Sir, thanks a lot for the great and detailed 2 Videos about the MFC L3770 CDW.
* Maybe same day or few days after printing 90 pages (duplex) with non-brother toners, my printer same model was also dead.
The issue is, that no light, no sound is coming from the printer anymore.
* So I went through the instructions on Brother homepage to revive the capacitor (not worked out)
* I replaced the diode on the power board thinking the power board was blown off.
* Fuses were unsoldered and checked > okay.
* I ordered a new power board and tried it today. > still not working (100€ cost, trying to send it back)
What could I try next? Any Ideas where I could look into ?
I was thinking whether the touchpad / board could be malfunctioned. Any suggestions, how to check it. I unscrewed the cover off, but see a thin cable-ribbon. No idea how to check this.
Other idea is to replace the capacitor on the main board, but since the revival tries failed, I am not sure whether this could help.
Looking forward for your ideas and suggestions.
You are the BEST!!!!!!!!!!!!!! I was flustered and stressed thank you sooooo much!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Helped so much thankyou
Bedankt
Thank you. The reset worked.
You still need to replace the capacitor to fix it properly by replacing the supercapacitor. Everytime the printer goes into sleep mode you will not be able to turn it on or wake it when you send a print job. If you keep running it with the failed capacitor the board Burns out.
@@TerryJonesPrinterRepairs thank you, will look into it. this issue started a couple nights go when i was printing something and forgot i left one of the paper drawers open, from there it was saying something about cooling down on the screen.
Perfect, thanks mate!!!
cool, my friend always shoot in manual mode to stop focus shifting all the time :) manual ISO setting and use a tripod with 90deg arm for hands free shooting,
U beauty first fix worked
It worked🎉 😂
Thank you it’s works
MFC-3750CDW here, about 1.5 years old. I just discovered that it won't turn on. I had to do the press-hold twice before it came alive, but I guess that means the super cap is kaput. 😕
Thank you
thank you sir
I have got a 2 year old HL-L8260CDW which is dead. I didn't know about the power on trick before I shipped it down. On my printer, the capacitor is not there. The factory solder pads are there. Have Brother updated the printers to not use the super capacitor because of the trouble they caused. Is it moved to a different place?
The printer was bought new and I am the first person to open it.
Hello
I dont have similare issue , the mine has a light but wont turn on, maybe power suply card ?
Thanks for help
Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I have a DCPL2550DW and I think, based on not being able to get the thing started in the way you demonstrated at the beginning of the video, that the power supply is shot. Very frustrating, as I've only had the thing for 2 years or so. I was wondering if you have any insight wrt why this might have happened? Could it be that the wiring in my place is shoddy in some way? Or are these things just not really built-to-last?
Thanks,
Jack
Good afternoon, Brother L 8650 DW when you turn it on, only the screen with the logo and digital dialing turns on, then it disappears, the logo remains. Previously, it was possible to start by unplugging the 220 pin from the rear, but now it doesn’t help, is it the power supply or super capaсitor?
I had some electrical issues with my neutral wire in our service shutoff and the voltage must have fluctuated and it destroyed the circuit board in my stove/oven, my satellite tv receiver and my brother mfc-j485dw even though they were all turned off.
Which component on the printer circuit board would likely be susceptible as I haven’t yet opened it up to check if there are any obvious visual signs of burning or melting?
Very informative and great troubleshooting videos! With rated life cycle of the super capacitors going down, would you suggest turning these printers off when not in use or still leave them on?
You can turn them off if you're using genuine toner cartridges if you're using non genuine or refilled cartridges the printer must be turned on 24hrs a day
@@TerryJonesPrinterRepairs Thanks for the great video, very interesting!
What do you mean though with " if you're using non genuine or refilled cartridges the printer must be turned on 24hrs a day"?
Is there a specific reason for that? (Or was that a joke?)
@@Defcon2000 non genuine chips have a battery on them that goes dead within 72 hours of the printed being turned off
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
I have the same issue with the green light, would be great to get an answer.
@@ps4benzol734 Same issue here - just a green light but nothing else
Yay, that's mines problem
This is exactly what I need. What are the specs of that super capacitor or where can I order one? Thanks for the video!

@@TerryJonesPrinterRepairs Thank you, sir! I'll check it out! One more question, what was your reason for not removing the board from the printer and working on it that way?
@@Shillkith removing the board and removing from the underside creates a new layer of unnecessary risk. The boards are not double sided but are multilayered. Removing through the board can break internal layered connections rendering the whole main board and printer scrap.
Do you need to replace capacitor? Can you just leave it on?
What happens when you leave dead batteries in something? That Supercapacitor is soldered directly to the motherboard. What do you think will happen.
@@TerryJonesPrinterRepairs I have no idea.
Dear Terry, where to buy the capacitor? My L3770 has the green power blinking and won’t turn on the panel. Is it due to this capacitor issue ?Thanks.
www.fixitfastelectronics.com
I tried to get to the power supply on mine. The bin it went.
Well if you want to fish it out of the bin here is the video that shows you how to remove the power supply ruclips.net/video/h6faiDy5sSc/видео.html remember it's not necessarily the power supply causing your printer not to turn on.
Hi Would this super capacitor issue also apply on brother L8699CDW ? I have two machines with same issue, i can see power button lights up but won’t turn on,
Tried reset more than three times but still not power up
You have a firmware issue. Plug a USB cable from your laptop directly to the printer and update the firmware
hi Terry, my problem is similar, I have a brother 8900. when the machine is turned on the green light is on ..LCD is dark nothing else comes on.... any feedback
You have interrupted the printer in the middle of doing an update and have bricked it. You need to run the update again with a USB cable direct from the printer to your laptop
@@TerryJonesPrinterRepairs Terry any feedback to to remedy this crux if you know, screen still black ... Thanks
Are you working in an aviary or a wild place?
Hey, I have a similar issue with an MFC-L3730CDN. It shows a green light (stays on) when plugged in and does not start with any of the shown methods.
Alright expect a video soon
@@TerryJonesPrinterRepairs I have this same issue. Please help!
@@TerryJonesPrinterRepairs Thank you for the reply, looking forward to the video!
Hello Friend i need help
I have dcp 3550 there is a light but wont turn on, any Idea?
You have interfered with the printer while it was halfway through doing a firmware update. The result is a bricked printer. You will need to update printers firmware through a USB cable connected directly to a PC
If i succès to fix it i send you gift from France i promess you
@@TerryJonesPrinterRepairs
Hello i updated and now it seems to works because i hear the fan and the bip but it still no display.
Hi
terry how are you? Thanks for your video if you don't mind i have a question?
A customer brought me a brother mfc 7360 it goes on normally abut when i make a copy it goes off & on automatically can you help me please?
Does it go on and off when you print a user data list under "print reports"
@@TerryJonesPrinterRepairs yep it's keep going on & off after i plug it to the power now.
Thanks for your instant reply.
@@7amdi79 The Laser motor is more than likely faulty.
@@TerryJonesPrinterRepairs thank you so much i suspected the fuser unite & disassembled it & checked it by the avo but it's ok thank you again.
@@7amdi79 compare the laser motor spin-up and spin-down sound to that of another printer that uses the same toner cartridge just see if there's any audible difference. Also check the drum and toner cartridge are not crap compatible but are good compatible or genuine.
I have a Brother MFC-L8900cdw green light by the power button is on but the rest of the machine is dead. any ideas? I already did your test here and nothing
You turned the machine off while it was in the middle of doing a firmware update. Now it is bricked, as in a big square heavy object that does nothing. I have a pay-per-view video coming up that shows you how to fix your problem.
@@TerryJonesPrinterRepairs ok let me know how when available pls
Mine is MFC 9140cdn power board replaced but still no power. Any advice please
Have you done the test outlined in this video at the start
@@TerryJonesPrinterRepairs yes I did
@@brotuvic789 then your motherboard is faulty
@@TerryJonesPrinterRepairs okay any idea when I can get the part? I'm in Nigeria
Mine is MFC 9140cdn it just comes up and trips off again, and does so repeatedly
The network adaptor is damaged on the motherboard. You need to replace the motherboard. You can use another 9140 or you can use a 9330 and update to wifi capabilities
@@TerryJonesPrinterRepairs thank you for this
Thank You so so much
Thanks ❤
