How do I take my viking lily 555 apart safely, to fix and clean myself. I cant afford to take it to a dealer.

Computerized touchscreen machine, so it sounds like a software boot issue. The only way to fix is dealer service.

check with your local repair shop

I just repaired a Husqvarna Viking Lily (555?) in which the orange backlight of the LCD was lit but the display and the rest of the machine was otherwise inoperative.

There was a bad 470uF 25V capacitor on the main circuit board that read 50uF when I took it out. I replaced it. I also replaced the 4.7uF 63V one nearest to it but I dont think it was bad.

The machine came back to life straight away. There was horrible ripple on the 5V supply before and afterwards it was still about 1V AC but much better than before. Maybe putting in a larger cap would be sensible, or even a Low ESR model. Its the rightmost capacitor in the picture, blue, third largest, horizontal orientation.

I used the service manual from here, it shows how to disassemble the machine and take the PCB out:https://download.cloudatcost.com/download/ex36merptmkszez76il2jplsi

Hope this helps somebody.

Make sure the presser foot is in the up position. This will open up the tension disks. It takes a lot of patience to remove imbedded thread. Use tweezers to grab the thread. Rock the handwheel backwards and forwards to help release the thread. If all that fails, have it cleaned by an authorized Husqvarna Viking dealer. You can find your nearest dealer at the viking website - http://www.huqvarnaviking.com/us

use the tool in your accessory box, otherwise take the machine to your authorized Viking dealer and have them put a new bulb in.

If still an issue, suggest you visit an authorized Husqvarna Viking dealer for assistance. They are usually eager to help. You can locate a dealer near you by visiting the husqvarna viking website and clicking on the Dealer link on the left-hand side of the page - http://www.husqvarnaviking.com

Good luck.

Check with your local Husqvarna Viking dealer. That is what they are there for.
The foot control is a little pricey for that machine, but why would you want to take a risk on cheapening your experience with your machine that you "ADORE" by trying to take the cheap way out in getting a part for it.
Get what you need and continue to "ADORE" your machine.

Try ebay or contact an authorized Husqvarna Viking dealer. They should be able to order you a replacement manual. Check Husqvarna Viking website for dealer closest too you.

I have had this problem, easily fixed by twisting the rubber knob that is in contact with the spool to the left.
