Gauge Cluster Problem

[Poetstylez]

A while back I changed my dash & the same day my MPH gauge went dead & the check engine light came on...so, I took it to the shop & the computer said my speed sensor was bad! I was like, ok, no biggie! I posted that whole scenerio on here & 1 of the tech guys said the maybe I blew my MPH Gauge on the cluster itself! so I just took the cluster out to make sure everything was plugged in right & it was so I plugged everything back & guess what.......now the only working gauge is the gas! the MPH, temp, RPM, seatbelt sensor....all of its out....yet the cluster still lights up! Is the circuit board THAT sensitive that if you plug & unplug it too much...it goes bad? I just finished cleaning the circuit board to see...but, has this ever happend to someone else?
