Fixed the fan. It was the connector on the little PCB which didn't survive the trip from France to me. Swaped it from the old panel and now it's happy again.

- H shift board
There are two (very) little trimmers that shift blu and red rasters horizontally.

-Vertical board
There are two (very) little trimmers that shift blu and red rasters vertically.
There are also two (plastic white) trimmers that expands (or tightens) blu and red rasters vertically.

- SMPS board
There's a trimmer (plastic white, not sealed) in daughter board that expands (or tightens) the raster of ALL TUBES horizontally.


The red raster dialed right in although it took close to ten turns. The blue however didn't move at all. Tried both directions to rule out a bottomed pot but no response. Do I need a new vertical board?

Are you sure you were turning the pot? I've never had that before, but if you are indeed turning the brass screw and it does nothing, then yes, you need another V board. I've got lots here if you need one.
