d-pad is stuck in down position

when synced the down button on d pad is stuck in down position. up, up left, up right do not register. i suppose that is because the down is always active. Had sync issue and changed caps. Fixed that issue but now i have this d-pad issue. Noticed when i hit strummer down the d pad isnt stuck in down position anymore but when i release it, it becomes locked again. Also up side on strummer doesnt register.
