Guys
Likely the control board or geom/focus. Look for glycol leaks between red and green tubes onto the top mother board.

Indeed the bow settings are generated on the CLM -along with pincushion. therefore it would be strange if only the bow is not working but the pincushion does.
Anyway be careful with changing around CLMs on a well set-up system, because it may lead you to projector reinitialization with all your settings being lost.

It seems the issue is caused by the geometry board. Bow works again after changing the board.
thanks for your support
