Husqvarna Viking Designer SE repair 

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!

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.

shes a lucky lady to have such a smart hubby..

Thanks for your video. had the same symptom with Designer SE, I replace all the capacitors on the main board. All good now

Just remember I repaired the machine Feb of 2018 so part numbers may have changed.

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!

This is exactly what is wrong with mine, it now takes an hour and a half to turn on, I wish you were my neighbor

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.

I was able to fix mine with new capacitors, in 2020 you can't even find a bord for it. ( pre covid)

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

great work... i have rubby.. can i change oils inside or never needs?

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

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.

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. For Rose owners I have posted this video for their reference. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wbhzDcVioww.html Thanks again.

What specific capacitor on the motherboard is most apt to cause the flashing light proplem?

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?

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!

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.

What is the MUSIC score you used on this video?

Did we ever get a part # list? It seems like what I am finding on Mouser, you have to buy a batch of 100 or so.

Buongiorno anche la mia macchina da cucire ha lo stesso problema, sono andata sul sito muouser.com ma non sono riuscita a trovare i condensatori, mi daresti i codici per ordinarli, o c'è un kit già pronto? Un' altra cosa la prima scheda è quella sotto la macchina da cucire mentre la seconda scheda è quella del display? potresti rispondermi in monjja@libero.it.. grazie
