The power light nor screen will come on when I give it power and press the sensor inputs or plug in any inputs. I tested the power supply board and that's working fine, so it's either got to be the main board or something with the sensor. I was thinking of replacing the sensor switch board for pretty cheap but do you think that will solve the issue? Or is it more likely the actual sensor input, or something with the main logic board?
RE: U2414H - won't power on, not a power supply issue
Dell does not recommend opening the monitor to replace parts. Dell replaces monitor if it has failed under warranty. We do not have ny information for opening the monitor and replacing any parts available for the customers.
