I should  have added if it wasn't clear that you need to remove U1 before 
trying the  heated socket procedure.



-------------------------------------------------------
Think I must have removed the chip before soldering the joint, but cannot  be 
sure a year later. Being on the bottom side of the board it is accessible in  
any case, though could be difficult to refit as the LCD display prevents  you 
supporting the board at the opposite side to apply pressure.
 
As you cannot get at U1 pin 1 on the top side of the board due to the LCD  
display, without removing this the method is to shave a "V" off the edge of the  
plastic corner of the socket at pin1 with an Exacto knife or similar to 
expose a  small area of the tinned print of the through hole in the PCB. Take off 
enough  to insert a very small pointed soldering iron on the socket side of the 
front  panel board and solder it quickly. Speed is the secret and small 
diameter  solder/soldering iron bit. I have both so no problem doing the work.
