The STKs are common and if you have an experienced electronics tech
around they can replace them for much less money but the tech must have
advanced soldering and IC exchange experience.
The STK ics, two of them, can be purchased on line for around $20 to $40 each.

Partstore has two models available - one for around $40 and another for around $55.
The part number is STK392-110 and if you google you can find them for
as little as $6/each but I don't recommend the cheap ones as they are
not reliable.
It takes a good tech around 3 or 3 hours to take the old ones out and
solder in the new ones. Also, it is likely one or two resistors are
burnt and will need replacing as well.
