got some off readings on ic3 of a 25incher. pin 2 is 20v pin 4 is 21v pin 5 and 7 are 20v. would this be a simple repalcing of the chip or need I look elsewhere in the circuit for what causing these voltages?

could be cold solder or a cracked trace around IC3.
re-flow your yoke pins and check the traces in that area as well.
then check to see if D13 is good or not.

D13 is got to be good if theres 20vs on pin 6 of ic3
odds are the ic is bad a la7831
