Hello i have 2 of 7" screens that accept RGB analog input, everything work nice but i have problem with colour and Brightness. The IC's that drives take signal are: D3031 and IR3Y31M, they have sw point to switch between RGB and CVBs signal.
I know the pinout of the IC's, correction of colour, bright and contrast is made by DC voltage applied to specified legs of IC.
And here i have a question. Can i just use potentiometer and solder leg 1 to ground, leg 3 to 3.3V and leg 2 go to the points that regulate contrast, bright and colour? Or someone have other idea?
