So napansin ko yung isang column ng keys sa keyboard ko pag napress, may nasasamang key sa ibang column pero same row. For example, yung T pag napindot, sumasama yung Tab. Pero di vice versa so pag Tab naman, walang Letter T. Same situations sa F4 & Esc, 5 and Tilde, F & Capslock at V & Shift.

Nagsimula to ng umulan ng malakas pero di naman basang-basa yung keyboard. May cover nung time na yun so isolated lang sa mga keys na to yung problem. Parang natuluan lang ng droplets.

Keyboard Tester diagram for clarification:


Anong possible cause neto? PCB ba or yung mga switches mismo? Fixable pa ba?
