"HELP"

Over the last two weeks I have been trying to tweak my PG

Last night while I wanted to adjust the width on my NEC PG6XTR I accidently turned the H OUTPUT CONTROL knob on the Deflection Board.
Instantly the Picture when blank and them came back when I turned the knob the other way.
Currently I can sync but the picture is not quite right.

Have I done any irreversible damage?
Is there anything I can do to correct this?

Thanks for any assistance.

you never want to touch this control, it needs to be set specifically for your PG to work correctly.
I'll dig through the service manuals and see how to recalibrate it. You wanted the other pot for H-Width, but you should be very careful with that one as well, you can blow the def board by adjusting it, or wreck your tubes by going too wide.
