Kork Ex-800, Buttons can be rebuilt!! Yay! (EX only not Poly Sorry!)

Kork Ex-800, Buttons can be rebuilt!! Yay! (EX only not Poly Sorry!)

2007-01-05 by Erik Hines

Just some info for EX owners: put down your solder guns, The buttons
on this puppy can be refurbished easily! With the help I got from you
guys on button replacement, I went in for 'surgery'. After removing
the top board, and closely looking at the buttons, I noticed they are
a simple 5 part assembly that can be taken apart and cleaned! My
buttons are working like new again (and no pesky solder burns)!! Once
you remove the top board and remove the 2 cables, look closely at the
buttons underside. There are 2 black 'clips' that attach the button
face to the actual switch. Carefully and slightly wedge a small
flathead screwdriver at the bottom corner edge of the clips to
release it from the tab and remove the button face. Next, you want to
carefully use a pair of small tech pliers to 'pinch' close the white
botton shaft that is held to the switch by two small tabs at the top
and bottom of the switch (be careful here, you can easily lose the
internal contact inside the switch, I recommend working on a clean
table or in a clean room) Once that is removed, you should see the
copper side of the internal contact, I had to tip the board upside
down to remove the contact, put in a safe place.. Next, get some
alcohol, and about 10 q-tips. Roll the q-tip between your figers so
that it will fit inside the hole in the switch where the contact was,
dip in alcohol and insert into the hole, rotating the q-tip to remove
debris. Next, use the other end of the q-tip (and alcohol) to clean
BOTH sides of the internal contact you removed, clean well, as this
is the part with the most debris. Replace the contact into the hole
(copper side up), replace the white button shaft (tabs top and
bottom) and finnaly the button face..Voila!! A brand new
(refurbished) button... Do the buttons one at a time, or else your
asking for trouble losing the contacts..Should takE about AN HOUR TO
DO ALL 15!!

Hi Erik,

I really think we should post your directions onto a web site
somewhere since fixing those buttons is probably a number one
maintenance issue for many Poly and EX owners.

I could put a page together on my MKIII blog. I might call it the
maintenance and repair page.

With your permission of course.

Mike.

I agree, and give you full permission to post the details wherever
they would be helpful. Pictures are probably necessary for beginners
as well, unfortunately the pics I have are from a cell phone, but
still might help...

Thanks a lot Erik!

The pictures look great, I think they should definitely help a few of
the fellow EX'ers out there...
