I'm a murderer. I repented, I corrected and ask for help. I want to buy "F1" and "SPACEBAR" for my K90.
Problem # 1: SPACEBAR is a Cherry type (a little horror), but F1 is a membrane type (real horror).
Problem # 2: I'm in Russia, Moscow.
Not a problem # 0: I have a card with non-russian money.

There is one more problem. Two or three LEDs flicker after turning on the backlight. After 5 or 10 seconds, they go out. How do you solve this problem? I opened the keyboard, but did not see any damage. Should I solder contacts or do something else?
