Once you've fitted the IC socket and put the IC in, working on the top side and measuring on the actual IC pins, check you have continuity (zero ohms resistance) between the following pairs of pins:-

UG5 pin 8 and UG5 pin 9
UG5 pin 4 and UG5 pin 1

Let us know how that goes. Don't power the machine up until you are sure those connections are present.
