I have a PSR 8000 I'd like to sell. It is in great working condition besides the fact that one of the keys would sometimes be inaccurate in its touch sensitivity. I paid a dealer 125 dollars to replace the strip and the problem was fixed.

However it is now two months later and I am in a different city and have just turned on the machine for the first time since checking that the key was fixed. It seems that the guy forgot to reconnect my microphone input. It won't be possible for me to bring it back to him and besides I'm outside of my 30 day warranty.

Should I attempt to open the keyboard myself and reconnect it? I don't want to spend another 125 dollars - I won't make a penny on it if I do! And is there somewhere I can get a technical description on how to take this apart?

Thanks everyone
