Re: Toshiba 19SLV411U
From the class notes … and stuff.
Grayscale can be done if they don’t give you all 6 controls … 3 on top and 3 on bottom. Two on top and two on bottom should be possible. if not … then crappy crappy tv. May have to spend $20 and buy service manual for it.
User manual shows Blue Driver and Green DRiver as all there is. These are your grayscale controls. Red held constant. Pick a mid level pattern and look for a best fit for all grayscale levels.
