K1 (2040) speaker dead

[Ruchan Ozatay]

Hi guys,

To day, first time I started to use my K1 (2040) with headphone (headphone for walkman) and it worked perfectly. After a while I disconnect headphone to use it with its own speaker but the speaker didn't work. I checked headphone again and again it was OK but when I disconnect it there was no voice heard from the speaker. Speaker was completely dead.

 

Can some one tell me what happened?  before I open the K1 for checking.  

 

Any answer and advice would be appreciated.

Ruchan,

When you plug the headphones in the jack is designed to disconnect the
speaker, of course.  For some reason, when you removed the headphone plug,
the little contact which is supposed to snap back into contact to make the
speaker work again, is not doing so.  You may have used a plug which
possibly was not a standard size which deformed the inner workings of the
jack.

You will probably have to open it up.

Ruchan,

This is a known problem with both the K1 and K2.  The earphone jack goes bad.  Must
replace it.  Quite a chore.

Right now the jack on my K2 is open on the speaker side, just like your's.  I've already
replaced the jack on my K1 and was hoping I wouldn't have to do this on the K2, but alas,
it is now also broken.

My seven-year-old K2 has yet to experience a phones jack problem. That might
be just luck, but I have done something a little different that might help
as well.

I use a lightweight pigtail with a plug in the K2 instead of hooking the
phones directly to the jack. I did that because my favorite phones had a
1/4" plug on the end, and I did not want to subject the jack to the stresses
involved in using an adapter stuck directly into the front panel.

Looking at any in-line adapter, it's pretty obvious that any side force on
phones end of the adapter will be increased by 10-fold (or more) inside the
jack as the plug moves slightly in the sleeve. That means that an accidental
tug on the phones wire of only an ounce or two can translate into a pound or
more of force being shoved against the mechanism inside the jack as the plug
rocks within the limits allowed by the ground sleeve. It's not much better
if a miniature phone plug with an inch-long stiff finger grip is used.

I used a miniature right-angle plug for the rig end so that if the line was
tugged, there'd be no mechanical leverage at work to increase the force on
the jack mechanism.

I don't know if that's why I still have not had to replace my phones jack
after 7 years of heavy use. Knowing how I can accidentally run out of phones
cable at times while I'm operating, it seemed a good idea to take the
precaution, Hi!
