here is a good example for set the colours as best :
all colour bars stops on number 2, perhaps we can put much but personnaly I stayed like this (this setting is made by RGB pots on chassis, it tell us exactely the same quantity for each colours)
after that I set the RGB gain on deported pcb behind the door and put all pots in the same position (just until I get enough colour power)
after that I setted the contrast pot on the chassis to the middle
I putted it a bit more than middle on deported pots for having a good luminosity
and finished with brightness for have the best black
I m not sure to have the best result but I think my setting is correct
