I have done the power on test and the LCD does not light up. The 2 fans on the base both came on. The PI has red and green lamps showing through the side of the base. I see the DC to DC has a red lamp on it. I am not feeling any heat issues (I physically touched the components). I have swapped the 2 cable positions. I did rotate the connectors when required. I tried the contrast on the LCD no difference. I have checked the wiring and it looks good to me. Does anybody have a suggestion on what to do next?
