I have a strange and annoying problem.

When I set the projector in ceiling mode, the rasters (all colors) assumes in the corner a irregular shape as schematical design and picture below.
It's impossibile to make convergence.

In table mode the rasters are perfectly regular, NO ISSUE.

I tried to swap hor defl and vert defl boards, but no fix the problem.

Any suggestions?

The issue seems to be in convergence tray, I tried to swap whole tray from another working BG808.
The problem seems to be less.
Perhaps one board of convergence tray is bad or defective.
I will try to swap boards one by one.

I think that is the convergence driver board R762518 to be defective
Unfortunately I only have one of the last version (808s)

I don't understand why in table mode the issue there isn't!!!
