mbed with the application board is not working

I compiled the hello world with LCD downloaded it , pasted it to the mbed drive, I could see in downloading I then pressed the reset It blinked a couple of times was off a short time then back on, nothing else happened. I think it should have said Hello World on the LCD ??

If you are using LPC11U24, please refer to following thread.

Yes the background lighting does come one when I connect the USB cable. I have not tried other programs. I am very much a newbe and was not sure if I had it right. Do you have a recommendation as to which one to try?

Could you link which program you used? Because if I check the application board page (http://mbed.org/cookbook/mbed-application-board) the helloworld programs of the LCD display do not write "Hello world", so if you expected that I wonder if you maybe used another program, for example one which prints it over the USB connection.

This program should at least write to the LCD: http://mbed.org/users/chris/code/app-board-LCD/docs/a87e255a8f3a/main_8cpp_source.html

Thank you very much for your help. I did try the hello world that blinks the LED and it worked. Maybe I am using the wrong program for the LCD on the board. I will try the this links. I am sure the hardware is fine. It is my lack of experience. Thanks

What does it do? Do other programs work? Does the background lighting ot the display work?
