Title: Problem Filco Majestouch 104 (1st generation)
Post by: ryuzBIM on Sat, 28 April 2012, 16:48:23
Hi,
I just bought a used Filco Majestouch with mx Brown, everything was looking good until i noticed a problem.
Sometimes "r" key input is registered twice wich is quite annoying.
Do you think the keyboarrd i just bought is dead ? Or can i repair this easily ?

Thanks

Pretty straight forward fix.. check solder points, if good, then it's the switch.

I think they're plate mounted, so you probably wouldn't want to desolder the entire board just to swap out one switch.. so you get a good knife, and CUT out the top of the switch carefully. and replace the innards of that ONE switch with a repalcement.

Oh ok i see thank you, i'm gonna check everything :)
I was kind of worried about desolder the entire board but your way seems pretty fast.

TP4 spreading FUD again. You only need to desolder ONE switch to swap the switch.

So the best thing to do is to desolder and swap the switch anyway ?
Thank you laffindude :)

If you're comfortable with soldering, sure. MJ1 are easier to desolder since they don't use through hole soldering.

There could be something stuck in the switch, try blasting it with compressed air before you replace it.

Explain how he's gonna lift the entire plate by only desoldering 1 switch...

You don't. Switch lifts out.

Desolder both points on the switch and then push from behind on the center....very easy.

I've had two Majestouch 1s do this.

One of them had a switch that wasn't snapped into the plate properly before soldering, and it was supported only by the solder joint, which started to come apart. This was a known manufacturing fault that was resolved with the Majestouch 2. The switch itself could be pressed down a millimetre or so, and then snapped into place properly and died. It needed re-soldering.

The other one, the switch just needed some WD40, apparently.

I'd be weary of peeled traces when the switch get seated into the plate after it has been soldered.
