Problem Solved!! Got my board in and plugged it in. Works like a champ!! It even uploads and works fine with only USB power.

Lesson learned - stick with the genuine article. You may not be saving anything with the cheaper ones.

Thanks for the help!!

Hi Paul,
Thank you for a quick reply. Power draw was the first thing I thought of because of the larger display, so I put the assembly on a 7.5V @1A external supply and made sure it was running OK before plugging it in. The regulator got warm, so I think it was taking at least most if not all of the load, but I got the exact same error message.
The one thing you mentioned which might be the actual reason is the fact that it is a clone. It was pretty cheap, and made by someone I didn't recognize. I think at this point it might be a better use of time to order a genuine Arduino board, that way I will know what I have before spending a lot of time.
I will let you know how it works when the new board arrives. If anything else comes to mind, I'm all ears.
Thanks for your help!

Evaluation Tools / NHD-4.3RTP-SHIELD-V Problem

Hi all. I am working on a project using a MEGA2560 clone and a 3.2 display board. I need to move up to a 4.3 display so I purchased the NHD-4.3RTP-SHIELD-V. The problem I am dealing with is when I install the display board, the computer will not recognize the USB connection and says it is malfunctioning. I tried it with and without external power and no difference. If I remove the display and plug in the MEGA by itself, everything is fine. I can upload the example. I can then replace the display, power up the unit and it seems to work fine. I have not seen this problem at all with the 3.2 display.

Has anyone else experienced a problem like this???
