hello so umm I have a problem with my razer huntsman (the one with a num pad) 

I’ve had this keyboard since almost 4years and never had any problems until now

At first I noticed the led lights. At a random day the lights weren’t working no more. Only three keys had the led lights, rest of the keyboard didn’t have any.
(I attached a pic)

(before someone says have you looked into razer synapse, yes I have. Everything on there showed like it usually did. Even the light-modes were the same I’ve always had.)

However after a while I noticed the delay when typing.
I type pretty fast and some keys wouldn’t even type the letter, even clicked twice on it.
Even Spacebar and the Enter key had a delay, actually let me say, all of the keys.

I looked up how to reset my keyboard and did the key combination thing with spacebar, caps and esc and unplugged n plugged it back in.

well guess that was the final stage of my keyboard.

The few lights from a few keys are no longer on, nothing works, can’t even type no more.
This keyboard is now pretty sure dead.

is this my sign to buy a new one? I mean it worked until a random day.

Should I get a new one? Cuz ion think this is fixable
