633 having issues.


New member
I received my 633 today and installed it. The test program works fine. But as soon as i install the module in CC and click on test all the spaces in the display turn to white boxes. If i open a page and look at it at an angle i can see that info is being displayed just still have the white boxes and cant see info straight on. Would appreicate any insite anyone could give me.

OK that seems to work a little better thanks. How come in the test program 30 works good but in the actual program it doesnt work.

I forgot to divide the 633 settings by half.

634/632's brigntess/contrast is set from 0 to 100.
633s seems to be 0 to 50.
