PC Peripherals Array of keys stopped working

[TheITN3RD]

I have a Cosmic byte Titan RGB keyboard, its been loyal to me through all the spills/dust etc. today suddenly a array of keys stopped working (Keys F1/1/w/s/x to be precise). this is a solid keyboard with all aluminum body , this is a membrane keyboard and not mechanical . I have popped the keys and cleaned the sockets but no use. funny thing is every other key is working just fine. Any idea how to troubleshoot this?

A membrane keyboard can get dust inside the two layers and make the keys to not respond. If you're confident enough, you can try to take it apart and clean the contacts and the membrane layer first with something dry (blower, microfiber cloth) and if that does not work, then applying some IPA on the contacts that are not responding. Typically dry cleaning should be enough though.

It does not seem like an issue with the logic board because then it would not have registered any key strokes at all.
