Hye, I need help with my filco ninja brown switch , only 1.5 years use suddenly the key registering is becoming erratic, sometimes double register, sometimes doesn't register (have to bottom out) I tried searching and some suggest using compressed air to blow the keys but some say that will ruin the switch. I'm confused, anyone have suggestions? Anyone know where can repair? Thank you!

Is it one/a few keys only or a lot of keys? Can you tell me which keys are affected?
Actual repairs, no pls. I'm temporarily out of the repair game until business is settled :3

Shit out of luck. Your controller = busted.

Your only options:
1. Buy alternative controller. Expensive, hard to guarantee success (personally have never gone this route, so I can't testify), and very tricky to install.
2. Scrap it. Salvage switches and LEDs, throw away board. Depending on switches' age and type, might be worth keeping.
3. Keep it as souvenir.
4. There is no option four.

I'd choose option 2 IMO.

Will he be the first?
