- Second time attempting to resuscitate this Husqvarna Viking 940. Trying to find the fault in this machine and not break it further.

Troubleshooting a non-working machine is an art. Having the right tools, access to replacement parts, a suitable workbench, plenty of light, determination, and grit (and maybe a little luck) are what make a great troubleshooter. The DESIRE to fix broken thing is something you are born with and the feeling of accomplishment when you get it right is immeasurable. -- You are doing all of us like you a great service by your videos. May you continue so for the next 40 years.
So true, it is an art. Thanks so much for the kind words.
I have a Husqvarna Viking 990 Prisma, mint condition all complete, all accessories and books. It is amazing.
Same, got it when I was 12 😊 about to have the capacitors etc replaced just to be sure the electronics are taken care of. Unfortunately Husqvarna saved on electronics quality back in the days
Wes, Thanks for sharing your skills and knowledge. Also thank you for your Service, and congratulations on your retirement. I got "the bug" when my wife started quilting and wanted a "featherweight" to take to classes. I've restored a half dozen 301, 4 and 500 series machines from watching Andy Tube. We bought our first embroidery machine today, a Husqvarna Designer SE and I watched several of your video's yesterday. It's in perfect working order, but I had looked at some that had bad screens, problems, etc. I'm thinking of buying a Pfaff for $100 and seeing if I can bring it back to life. I absolutely hate our throw away society today. Hoping it's only capacitors, I sent you and inquiry on your site. Thanks again for Everything. Ken
I had one of these from 1986-2020 when I gifted it. It had a failed circuit board at about five years, replaced under warranty against the will of the questionable ethics repair shop. After that it was trouble free. I kind of miss it.
Another informative chat! Thanks for posting this video!
Very nice video, it sound like my sewing machine issue...I will try to apply this guidance
I'm trying to fix the prisma 980 but it goes nuts when I press the pedal it goes fast with no slow start... Im stuck 😒 I replaced some caps and other parts but it goes to fast... Could you have an idea where I have to do next? Maybe a DA converter died? So that you step on the pedal it goes max 😬 help is needed. Pedal is ok kind regards Albert
I love my machine and do not want to part with it, I know it top to bottom.
I have a 2008 Chevy cobalt that I love and do not want a new car even with it having 159.000 miles on it. Best car I have ever owned. I know it top to bottom.
I would question, what the DC voltages are on the outputs of the transformer board, well that and the amps.
Good video. Haven't worked on many sewing machines, my field is mechanical/electronics, so let me know if I am incorrect about anything I say. Checking (testing) a capacitor in circuit with a multimeter set to the capacitance or resistance scale will tell you nothing useful about the capacitor except, in resistance scale it may show that the capacitor or circuit is shorted which equals a problem. The only way to properly test a capacitor is out of circuit and check for capacitance or, preferably, ESR with the appropriate meter. Question, have you checked the output and input from foot pedal to machine since it was returned with this problem. Good video, waiting to see what fixes this one. Thank You...
Yes, removing it is better, but checking it in the circuit can let you know if it is a dead short. Also, I have experienced capacitors that read properly on the ESR but are bad when under load. There is probably an expensive tool to check this, or just replace the capacitor, lol.
I had Husqvarna/Viking I bought in 1980 and it was wonderful for 25 years...until my pet rabbit chewed the cord to the foot pedal. I could not find a replacement. Silly me, I gave it away.
I don't remember the model number. It wasn't computerized so I don't think it was this one. I prefer analog, not digital.
Yep those pesky
over heated burnt out,
electronic components.

I have had several of those and am not impressed at all with the build quality of the machines. I even have a NOS circuit board for the model 990 that will probably go into the trash.
