If everything else is working, you have one more trace to repair. Test for continuity the trace from pin 2 of the IC31 to the nearby thru-hole solder pad junction. I had similar issue and this trace was missed and problem solved. Also check the resistor array as these are also affected sometimes and not easy to see damage.Hope it helps.
