I've now "listened" for a 20mhz signal and there isn't one. As it's a new chip, and a replaced (tested) crystal, I can't think what else it can be?
There is zero DC voltage on pins 9 and 10.

Just checked my U3 has 2.4/2.6 on 9/10. I see no reason the CQX should be different.
It is a genuine replacement from Hans? I do not know but if you have no voltage then maybe the fuse is wrong.
I do not think you will have the micro working if it is not clocked at all but something may well happen if it is clocked at the wrong speed.
