Thank you very much for the video. It was able to get a machine that been bead for more than 6 month because we can’t find a place that have a replacement board. Only take about 1.5 hr for me to replace those capacitor and machine come back to live, call the customer back that we tell them her old machine is back to live and seeing how happy and excited she was make my day.
Thanks for the taking the time to post this video. My wife has been starting up her Designer SE with a blow dryer for a year and a half now. I too had seen in the post by Flackmonkey how he had heated the capacitors to start his mother's machine. I finally got around to ordering capacitors as listed in your video. I ordered 2 sets of them and it was only a little over $60 delivered to Canada. The link to the manual made it fairly easy to get into the unit. I first replaced the capacitors on the power supply and the problem persisted. I then moved to the main board and replaced the remaining capacitors. Upon reassembly there were no flashing lights and it powered up just like new. I highly recommend taking pictures of the main board and everything else as you disassemble so that you can ensure everything goes back together the way it was. It is easy to plug a ribbon cable into the wrong spot causing your machine to operate in reverse only. Lol... My wife is happy to have her machine back to normal and I have another project off the list. Thank you!

Same problem; machine would not turn on cold. I replaced 5 of the 6 capacitors ( I forgot to order the 6th and didn't replace the 10v 1000mfd in upper right corner). The machine turned on perfectly. Thanks!
In video at 0:44 it says that 16v 1000 uF need to be close to same size as original, but i comment you 16v 47 uF should be. Which is right? Thanks for the video.
My designer se is blinking again I have replace the pc board twice since I purchased it. So disappointed they want another $600.00 to fix it and could take months to get the board fixed. Wish you were near me to repair it. Lee
Hector . . . was changing out my needle centering stepper motor. When I pulled the front case away from the machine, the large ribbon cable came off the mother board before I was able to see which 20 (40) pin connector it was plugged in to. There's one at the top and one on the side, just right of it. Stepper motor works now, but can't get material to move forward when sewing. Thanks
Debbie, it sounds like you have a feed dog issue. Although if the connector came off that easy, I would suggest to unconnect then reconnect all connections. That may be a pain if you have put the machine back together.
@@hectorguerra5544 I'm dying right now seeing there was something on here about the motherboard! Viking wants a fortune to replace the motherboard and I can't afford a new machine right now. The screen flickered for a long time.. I brought it in and of course that day it stopped flickering when the person from repair gave it back to me. Said they found nothing and 2 weeks later--- unusable! any ideas??
@@laurenmichelle5713 When you say unusable, do you mean the machine will not turn on at all and /or will not flicker at all? If the machine has no power at all then they disconnect something in the machine, other wise it should still flicker. If the machine had or has the same issues(lights flicker on and off) as stated in the video, the fix is to change all capacitors in both the power supply and the main motherboard. You will have to have someone in your area with electronic technical experience to do the job. The machines plastic shell must be taken apart to get to the boards. I too was going to take it to a dealer in San Antonio but then found out that my wife was going to get charge $2,000.00, at that point I fix it my self. Before I repaired my wife's machine I took the back off. This will expose the power supply. Then I took a blow dryer and heated up the power supply and the machine started to work. It turns out that by heating up the capacitors on the board and the motherboard they change values and the machine will work until you turn it off. The main motherboard is behind the screen. I aimed the blow dryer at the power supply and some of the hot air went into and behind the motherboard.
A straight pen was atop the upper tension dials... I attempted to retrieve with a tweezer. The pin fell into the housing. How do I remove the front plate to retrieve the pin?
@@hectorguerra5544 Thank you for your quick response; sorry mine was not so quickly. My sewing buddy who also was a HQ dealer at one time, advised me that the pin could have fallen to the bottom. So, I did as she said and turned the wheel very slowly.... was fine and nothing happened. So, I am back with the machine. TY again.
@@hectorguerra5544 Hi Hector. I am not getting an "About" tab on your homepage to let me PM you. I would rather not put my email out in clear text in RUclips comments.
My Viking Rose sewing machine the stitch won't increase from a 2.5 and I messed with the screw that controls stitch length any ideas? Would appreciate your help!
Donna, I am not a sewing technician. I am an EE major with 7 years of electronic tech experience. You will need to take your machine to an authorized dealer and have it serviced.
Got my Viking designer se from my aunt's estate. It worked about 1/2 hour and went dark. Took it for repair and they charged me to clean it and didn't fix it. Replaced transformer, but can't find replacement motherboard anywhere on the Web. Test equipment is pretty expensive. Any ideas on a replacement board? Janice T.
I would first try replacing the capacitor on the main board otherwise you will have to take the machine to an authorized Husqvarna dealer and have them repair/replace the main board. It will be expensive.
My wife has been using a hair dryer to slightly warm her SE. She just heats the area around where the power supply plugs into the machine and it fires up in after a minute or two every time. I am now going to change out the capacitors to fix it permanently as she is threatening to buy an new machine! :)
Interestlingly, after watching this video, I plan on replacing my esr tester with the one shown, I mean, the review here and on amazon and other places, it seems to be one of the best, and maybe what I have are good but they aren't really the greatest either, and I also wonder about a soldering/desoldering station, but I sure won't spend over $1500 for one for what little I ever do, but maybe I could look again at something that is better a setup than I have used, ...very interesting..... Anyway, I think this stuff sounds easy enough with the right tools and minimal experience, but I of course have former training, military and college, not that it really matters since I still feel like I am not experienced completely for most things, but do own some tools except a oscilloscope, but I bet there are many expensive machines out there not working owned by people who are told it would be cheaper to buy new, ...all over some issues most would have never realized would crop up so soon. Wow, now that is what I talk about, fixing things that can be fixed, but wow, I was thinking those SE's were newer, but yeah, I've done electrolytic change outs on old electronics from the 50's 60's, 70s', and even on computer motherboard once. That tester, ...seems like I have an equivalent but not as expensive or complex. But testing the capacitors for out of tolerance is I suppose better than just replacing all of them, but really, seems like you did. Mouser.com. yeah, that;s a good place for parts. When a person looks at even older high end viking machines, like the old #1 1200 I have, a mid 90's machine, a person can see on circuit boards for sale the massive size capacitors on the boards just itching to go out or already out of tolerance, after all this time, like I bought some spare circuit boards still installed in the side of the case,...just in case,....not cause I figure the capacitors will get my machine back going someday but only due to the imbedded logic on the microchips, for that old style heavy duty machine. But wow, that SE, I don't know much about what years those were made, somewhere in the last ten years maybe, unsure, but that was very interesting the board and what is on it, and the tools you used. I almost wonder if there was proper cooling of the electronics, or they got too hot due to environmental conditions, ...or the machines just run too hot, I can think of ways to fix those problems like I have on other equipment and computers, sometimes a person has to just get on down and drill extra vent holes and or attach a small fan to draw through the machine in various spots, like on computers or specialized audio equipment, or other......I do know one thing, the poster of this here knows more about electronics repair than I do, better tools too, great job, maybe he is a technician or an engineer already, or a computer tech.
By the way, alot of folks could learn a few things about electronics repair and with a few tools for not alot of money, even watching youtube videos,...and capacitors generally have a value stamped on them so a person knows what value to replace them with, or those worrying about knowing what caps to buy, I mean, come on.....its not really that hard to determine replacement values for caps, or anything else, I guess its diagnosing where the fault lies, sometimes its easy to see a burn out part, sometimes a person can detect a bad solder joint, but there are a lack of electronics repair people in this country cause its turned into a throw away world, so paying for repairs has gotten impossible, errr, to find anyone to do them, but like when I was a kid, those electronic project kits at radio shack were popular,...for kids, I forgot so much that I had to buy several of those recently to play around with, and some books, but eh, I am so lazy I could be an "expert" right now, but I don't do repairs anymore on vintage audio equipment,...ended up with too much of a collection, and have lack of knowledge of advanced modification of electronics,...errr, its all in the books and internet. Another thing to mention is safety, there is a safety factor to observe with capacitors, expecially the high capacity capacitors used on power supplies for appliances like microwaves,...well, unsure about the new inverter microwaves.......ya know, I wonder if the caps and alot of the components that were original were cheap chinese grade low quality caps,....used in a high end machine, it wouldn't surprise me, at one time about ten years ago I had so many electronics die on me prematurely that I was buying the extended warranties AND using them, it was crazy, I had only considered extended warranties in the past, but then I kept hearing about relatives having hd expensive tv's power supplies burn out after six months, all tied into hdmi use of blue rays, ...happened to me, ..twice, ..a computer burned out a cap on a motherboard of mine, I was dumbfounded, I actually desoldered it and replaced it, ...carefully....I think I know why, but this is already too long,..I mean, I really really enjoyed this video, thanks much.
Hector. Thank You. This solution fixed my two late 90's Husqvarna Viking Rose Type 600's. When the first went blank around 2013 I saw no obvious causes to the issue and found no leads on the internet to tell me what could be the issue. I know at the time I saw other people had posted that their LCD screens were also going blank. For various reasons I only replaced 3 of my 5 capacitors and they both came back to life.

great work... i have rubby.. can i change oils inside or never needs?
In video at 0:44 it says that 16v 1000 uF need to be close to same size as original, but i comment you 16v 47 uF should be. Which is right? Thanks for the video.
I mean physical size as well as electrical capacitance and voltage.

What specific capacitor on the motherboard is most apt to cause the flashing light proplem?
Not sure which one but to get the board out is a chore and it would be in your best interest to replace all of them.
I was able to fix mine with new capacitors, in 2020 you can't even find a bord for it. ( pre covid)
A straight pen was atop the upper tension dials... I attempted to retrieve with a tweezer. The pin fell into the housing. How do I remove the front plate to retrieve the pin?
If your machine is a Viking Designer SE you will have to remove both the back and front pannels.

Ok that makes sense. The pin would be under the feed dog area and should not be in the way.
