Hello, first time caller, long time listener. i bought a used Majestouch Tactile Touch ~5 months ago and recently it's started acting up. all the keycaps and such looked brand new when i got it, however i noticed the other day that the white sticker on the back saying "DO NOT REMOVE" has been punctured (probably by a screw driver).
The problem:
sometimes i press n and get nnnn, same with l, t, and i think backspace.
Diagnosis (so far):
1. i suspected a virus at first but i have tried other keyboards on my comp and none have exhibited such a problem.
2. i removed the n key cap with the tool i got and it's clean under there, and the switch seems to have no resistance when pressing down on it.
3. i think i did spill some diet coke on it once, but i turned it over and cleaned it out right away. that was some time ago too, i think this maybe the source of my problem however.
so basically, i need some help diagnosing the problem. do you experienced peoples think it's the switches themselves? is it possibly a problem with the circuit board? Should i attempt to spray some sort of fluids down into the afflicted switches?
Thanks for the help,
Bret

Key chatter isn't an unheard of problem with Filcos. I finished up scrapping mine for parts after that started. Good luck with finding a solution.
-
Liquids aren't a requirement for a Filco to have key chatter problems. But yeah, liquids wouldn't help matters.
-
let's just say this is a key chatter problem, does it only happen on filcos? also, is it possible to buy a cherry corp. lt. gray 104 key mech board in the states? i have looked on amazon and cherry's website but cannot find what i'm looking for. also looking at this board (http://www.amazon.com/SLIM-KEYS-MECH-KEYBKEYSWITCHES-TAMPOPRINT/dp/B003620BDK/ref=sr_1_58?s=STORE&ie=UTF8&qid=1280960382&sr=1-58), anyone know what kind of switches it has, and where is the ~ key?

The only piece of advice I can offer is booting from a liveCD/liveDVD/liveUSB (eg. a Linux liveCD) to order to completely rule out a software problem (as unlikely as it is). That way you completely change your software stack from the lowest level possible and up. I use it as a standard procedure every time a computer component shows signs of failure.
I don't think it is a software problem though.

It has low-travel mechanical switches. Not the nicest for typing on, or so it has been said.
-
it's fixed, i just squirted a little wd-40 into the few switches and i can type
n n n n n n n n n n n n
again with no problems.
i am afraid it may come back though and i checked mouser but i don't see cherry browns on there, anybody know where to get them?
p.s. i real want that realforce board but 250 seems like too much to me.

Just a note: I believe DeOxit to be more suitable for that purpose, since it is a specialized "contact enhancer" (and also slightly lubricating).
-
ya the WD was really just a test to see if that fixed the problem. I'm going to disassemble the whole thing, clean it with contact cleaner and re-lubricate with that dry teflon lubricant dupont makes. i noticed that people recommend grease but that will just attract more dirt i think.
Is there no one who knows where to get cherry brown mx switches in case i need to replace one?

I am amazed this relatively horribly expensive keyboard line has so many simple-yet-hard-to-solve problems with it.

Yeah, the Chicony KB-5191 that I'm *****ing about in another thread is probably coated with a seven-year-old Diet Coke spill.
