Better place for both of you to start is on the neck board. Verify continuity between the blue socket pin and the solder side of the neck board. You may have cracked the solder joint for the blue socket pin simply by removing and replacing the neck board.
The blue socket pin should be labelled something like BK IIRC.
Thanks for the help I will check out the suggestions , I have another issue though, on the invert board when it is regular I have a picture and the pods work and when I move the ribbon to invert the screen goes black , I purchased the invert kit from Bob Roberts but if it is something simple I don't want to go through all that trouble inverting the chassis
