Make sure you have no shorts between legs of chip. You also might want to go through and read all the Gm1- all Gm test points on t-con in numbered order.

Ok I'll have a look into the thing you call "reflowing the ic". No shorts are between legs of chip already checked, there is contact everywhere. I already went through all Gm points and everything seemed fine just that the last one showed 0 voltage which was weird to me and I don't know if it should be like that.

All should have a voltage and they should be in ascending or descending order depending on which way they are checked.
