It Might not be broken...Try this first, with the power off, Hold down the ' G ' key and turn power back on, this will reset the opt's terminal back to Factory defaults, depending upon which port it was hooked up to, You will probably have to change 2 or 3 screens. But, see if this works first.( It can't hurt anything )

I can see the light at the end of the tunnel..
