So if you turn the flyback down.... the brightness pot makes no changes still ?
(if you overdrive it with the flyback, you'll never see a change)

Is there a contrast pot ? Is it cranked up ?

Starting to sound like you have a bad pot.... just trying to verify or at least narrow it down.

Measure the resistance on the pot itself.

1       2
   
     3

1+2 gives overall value of the pot.
1+3 or 2+3 should vary from overall value down to zero when adjusting pot.

Best to remove the pot for testing.

I was going to compare your readings against what it should be......
Do you have a schematic or manual for that chassis ?
