Title: Novatouch - Some keys stopped working, any fix?
Post by: Hauksort on Wed, 23 September 2015, 15:20:55
Hey!
First off, no clue where to put this, might be better under some sort of support section. (:
I have a CM Novatouch TKL that has a few 'broken' keys, since my cat spilled water on it a few months ago. The keys are the shift key, '<','z','x' and the escape key. I followed some steps of a recovery post Ripster re-posted on another forum. I cleaned the PCB but nothing else changed, the same keys are still not functional. Is there anything I can do to fix the keys somehow? No clue if it's the switch or the PCB or anything else really, considering I'm pretty new to this.
I have another keyboard, a Razer Black Widow Ultimate 2011 edition that I have as a spare keyboard.I honestly don't like the switches at all compared to the ones on the Novatouch, so I'd prefer to not use it at all.
If there is no way to fix the switches or the PCB on the Novatouch, is there any way to splice the keyboards somehow to at least make the Novatouch as functional as possible?

I really appreciate all answers, thanks in advance!

Edit; changed the title a little bit!

Unfortunately Novatouch uses Topre switches and Razer uses probably Kailh switches (or Cherry, depending on its age) and they are completely incompatible.

I don't think I've heard of anyone spilling liquid on a keyboard with Topre switches before, hence little experience in how to clean one.

I'd guess that the contacts and everything would have to be super clean for the capacitative contacts to work, so you might have to disassemble and wipe the innards down with some sort of, maybe, rubbing alcohol.

But don't do that until someone else can chime in whether it is a good idea or not.  At least it might give you an idea what you might be down for.

The Razer keyboard has Cherry MX Blue switches. Now that I've been using the Novatouch for so long I don't feel too good using these switches, they're so noisy and don't feel as good imo haha
If there's no way at all to fix the keys on the Novatouch I guess I'll get a Realforce when I can afford it.
I don't have an issue disassembling the Novatouch as I've done it a few times now without any issues.

Unless you try thoroughly cleaning the contacts, and/or swapping some dome around, I don't think so.

But please wait and hopefully someone else with knowledge of the Novatouch will chime in.

THROW THE KEYBOARD AWAY. IT'S DEAD.

Haha, well it's definitely not dead, a few keys aren't functional. So that won't happen until I've managed to ruin it completely somehow!

Thank you!

I would try doing this:


Finally you could sell it for a discounted price and get a used Realforce instead

If cleaning the keyboard as apolotary suggested doesn't work, you could take the purple sliders out of the keyboard and sell them to someone here. You could easily recoup at least half of what you paid for the Novatouch in the first place.

Just pick a solder iron and replace a switch. Oh wait. :-X

Haha, I was stupid enough to leave a half full glass of water near the keyboard while at school. When I came back my mousemat was soaked and the glass was tipped over, so I immediately checked the keyboard for damage and dried it. For some reason she prefers my water over her own ):

Err, not exactly haha

Edit; Cleaned the PCB and the keys are still not working.

As I'm living in Norway it probably wouldn't be worth selling the sliders considering the costs of shipping them etc. (?)

Our cat does the same thing. Drinks out of our cups instead of the water bowl if we let him.

I'm guessing something must have shorted then, maybe a digital potentiometer, as that's what registers key presses on a Topre board IIRC. A multimeter might be able to tell you if that's the case. I'm not sure how many the Novatouch has, but my HHKB has 5 or 6 of them as I recall. This Deskthority thread (http://deskthority.net/keyboards-f2/adventures-in-topre-land-t7436.html) shows where they are on a Leopold FC660C if you want to see what they look like and try to test them on yours.

You can probably get away with shipping the sliders in a padded envelope, so I imagine the shipping wouldn't be too bad if you decide to go that route. I get stuff overseas this way all the time. If you do decide to sell the sliders, let me know :)

I honestly can't be bothered to see if anything has shorted, but it probably has. If I decide to sell the sliders I'll definitely let you know!  :)
I guess I'll have to keep on struggling without the keys, and who needs those keys anyway.. pffft
