Still nothing

#1
Thanks to Ray for trying with his whole heart.

Here are my printers symptoms:

1.) Screen comes on but no text, just 2 horizontal lines going across. Top row and 3rd row. Know twist changes nothing.

2.) After at least 50 tries, computer does not find Arduino board, con 1 or com 3. Re-loaded Arduino firmware, Arduino Mega 2560 drivers, USB = NO, Flash card + NO

3.) Checked and rechecked wire placement and connections

Any ideas from anybody?

Hey Don,

Have you disconnected every thing from the Arduino? then using a USB cable plug it into the computer. This is a good starting place to find out what is broken.

If this works, then plugin in one thing at a time and see where the problem is.

We already worked through that. I helped Don re-upload the firmware to the Arduino successfully. The power supply was off at that time.

Had him attempt to have Repetier connect to the printer, and we had a brief and partial success but once the power supply was turned on all communications froze up. I haven't seen anything to this extent before, usually with this amount of fiddling things tend to work themselves out.
