My Viking 190 sewing machine is stuck on backstitch. We opened it up and the mechanical parts all appear to be functioning properly, so it must be somewhere in the electrical/computer? The machine worked fine 6 months ago, then put it in the closet. Pulled it out for some mending and it won't sew forward--only backstitch.
Found the problem (s) with Viking stuck on backstitch!!!
Two problems:
A: machine is "gummed-up" form old grease.
Solution: degrease machine with a high quality degreaser.. I used a spray electrical degreaser from an automotive store. Turn the machine up-side-down to preform this!
Then relubricate machine. Use a high quality sweing machine lubricant! Also lubricate the inner parts with a qigh quality "Sewing machine" oil.
B: Found that the return spring from foreward to backward was tired.
Soultion: Replace with slightly stronger spring from local hardware store.
If you need pictures, I took very detailed pictures of the reverse mechanism and "return to forward" spring.

Two reasons the machine won’t go into reverse:
A: the machine is “Gummed-up” from old grease and oil.
B: The return spring is WEAK.
See attached photo.
The red arrow points to a spring that is weak. Replace it with a new spring from the hardware store. (Technically, I replaced the spring with a stronger spring ($.69) than the original equipment spring, works great!)
The area behind the blue arrow is where a cam reverses the sewing machine. Press the reverse button several times and you will see which parts move. Clean and re-lubricate these items.
This is where the machine is most likely “gummed-up”. Over the years the oils and greases gel. Being that sewing machines are intricate light duty vessels, the gelling of the oils and greases make it hard for the machine to operate correctly.
Procedure:
Buy an electrical degreaser (spray can) with straw sprayer from an automotive store ($6.50). I turned my machine “upside-down” and cleaned it with an electrical degreaser. (Turn upside-down because the sprayed electrical degreaser will drip and run onto parts that you don’t want to degrease.) Only spray the moving cam behind the blue arrow. Use the straw extender that is provided with the degreaser can to perform this procedure. This is because you only want to degrease the reverse mechanism and not other parts. Re-lubricate with “sewing machine oil” ONLY! This is important as the viscosity of this oil is correct for sewing machines. (oil $6.50)
Total cost is less than $15.oo to fix.
I can supply you with additional pictures if needed.
Get a spring that has hooks on both ends. If unavailable, cut new spring to desired length and use needle nose pliers to form your own hook on one end. The new spring doesn’t have to be exactly the same diameter as the old spring. The most important aspect of the new spring is the length and elasticity.

Machine would not go into reverse. Turned machine upside-down and now it is stuck in reverse and won't go foreward. Need explosive parts manual.

Thanks...
Is this a good machine found it for sale $25 with no electrical cord? What do you think
I've downloaded the update and unzipped it on my desktop as required, it appears on my USB stick after I run the update, but once I plug it into the sewing machine it doesn't recognize the file, so nothing happens.
