Hey, all! I've come across this forum on numerous occasions on my quest to fix this problem... I've been unsuccessful so I've come for help. I heard Filcos were pretty good keyboards, so I got one new on Amazon for only $100. I've had it for only 4 months or so, but many keys are giving me trouble. I have to pound on them slowly, one by one for them to register or not repeat... so it's taking a long time to type this for a person who's used to 90 wpm. o-o It seems like a localized issue-- the problem keys are T, Y, U, I, O, H, J, K, L, V, B, N, and M. It's starting to occur in left shift, too. Granted, I'm a pretty heavy smoker, but I dust thoroughly every month. I've checked for residue with a damp q-tip to no avail and air dusted inside the switches while they were depressed. I've never spilled any liquids on the keyboard. I don't really know anything about keyboards and I'm not sure what to do. I feel like there's something like stuck under the switches, or maybe if these particular keys have a shared source of power (
) that could be failing. I don't really know about warranty stuff, and I'm not sure if the presence of ash/hair (I have long, thick hair and shed a lot
) would void the warranty anyway. I don't mind getting down and dirty, though. Any advice would be appreciated. The model in question is a Filco Majestouch-2 Ninja FKBN104M/EFB2.
