I am amazed the module wasn't severely damaged or destroyed if it was plugged into the socket incorrectly. I'm sure if there were any kind of high voltage in/on that module socket, the set's line fuse (if it has one) would have blown instantly, or else the module itself would have been permanently damaged. Solid state circuit modules, as I'm sure you are aware, are nowhere near as forgiving of mistakes as were components in older, tube-type TVs. I don't know how long that 9-86 module was plugged into its socket incorrectly but in any case, you were very fortunate there was no damage, and the TV now works as it should. That the module was plugged in upside down could explain why there was a vertical problem, as well; however, I will say again you were extremely fortunate this mistake didn't damage or destroy other parts of the TV.
