[@TerryJonesPrinterRepairs]

@@denisdb725 Please explain Denis, why should they have demonitized my KZbin channel from the very start?

[@TerryJonesPrinterRepairs]

@@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 KZbin 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!

[@TerryJonesPrinterRepairs]

Your printer is not fixed you need to change the supercapacitor . You old supercapacitor will be leaking and corroding the board.

[@dinorocos8546]

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!

[@TerryJonesPrinterRepairs]

Your printer is still broken, you need to replace the failed supercapacitor before it becomes permanent off.

[@jonnymakers9560]

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!

[@ibrahimapaydin3457]

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.

[@TerryJonesPrinterRepairs]

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

[@TerryJonesPrinterRepairs]

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.

[@garyharrisonuk]

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.

[@ricohsil6261]

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?

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. 😕

[@brianbaker359]

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?

[@jackbarrett3599]

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

[@RaMpAgE3007]

I tried to get to the power supply on mine. The bin it went.

[@TerryJonesPrinterRepairs]

Well if you want to fish it out of the bin here is the video that shows you how to remove the power supply kzbin.info/www/bejne/nmfJkpx6rpqmicU remember it's not necessarily the power supply causing your printer not to turn on.

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?

[@TerryJonesPrinterRepairs]

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

[@Defcon2000]

@@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?)

[@nelsl9796]

Thank you. The reset worked.

[@TerryJonesPrinterRepairs]

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, 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?

[@TerryJonesPrinterRepairs]

@@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.
