Problem with DDJ T1

i need help. as ive checked google. youtube. nothing has helped

on the left deck i have a problem. the problem is that the play button has lost its sensitivity i.e i push it. and it doesnt always play. i cant dj until this is fixed.

sometimes it feels the click. i have unscrewed it from the back to see if i could get to the button manualy. however i found i couldnt due to all the microchip backboards. i really dont know wot to do pioneer dj's this is a really big problem.
