When I plug my Arduino/Ramps using the usb cable I get see the Marlin software on my lcd just fine. I can navigate the menus and make selections. When I plug the power cable into the Ramps the lcd is blue and no Marlin software is viewable. Now, everything worked just fine up until the point I plugged in two motors to the X stepper. I noticed that both motors were plugged in incorrectly. I switched the connection and the motors moved just fine. This is when I noticed that the motors would begin to work intermittently. I would have to spin the dial very slowly to get the motors to spin again which would work for a few seconds before it stopped for another few seconds. I unplugged everything and re-plugged the power cable and that is when I noticed the blue screen with no Marlin software.
I figure that I either fried the Ramps board or there is a loose connection in the green male or female plug. Since it works when plugged into the Arduino but not the Ramps. Any ideas as to what else I can troubleshoot.
I was not using that power block at the time all this happened. I was actually using this one
I ended up switching power blocks in case that was the issue. As you can see from the photo it did nothing to resolve the issue.

Thought I would post a pic of the board connected through USB.

So I was going to try repetier-host and plugged my USB and power block and I get this on the screen.

So another update, I plugged in the power block first then the USB and was able to have a normal screen. I was also able to drive my motors from this setup. I tested the voltage on the green connector to the Ramps board and I am getting 12v so no issue getting power there. I am thinking it might be a bad Ramps board because it was working fine a day ago and all of a sudden my LCD is no longer displaying the Marlin software.
I forgot to add this
1) Did you buy everything from here?

Firmware is from this site
2) Are you using end stops?
a)If so please disconnect them.
3) Are you using all my recommended parts?vhalikParticipantMay 27, 2016 at 9:04 amPost count: 8

If you unplugged the steppers while the ramps was powered up you probably fried your drivers.vicious1KeymasterMay 27, 2016 at 3:32 pmPost count: 2657
Let me try and recap. Your screen only works with the usb plugged in, not just the power supply?
If that is the case your arduino voltage regulator is probably bad.vhalikParticipantMay 27, 2016 at 5:13 pmPost count: 8vicious1KeymasterMay 27, 2016 at 5:59 pmPost count: 2657
