Motors, heatbed, extruder and fans not working

[JohnP]

Hi,

I have just finished building my G2 and have updated it to the latest firmware.
Lcd works fine when connected to USB and psu is connected up.

I can not get the slightest movement or sound out of any of the motors.
No fans work.
Heat bed does not heat up and its led does not comes on.
Extruder does not heat up.
Thermistors both register 23c and warm up if I place my hand on the heat bed or extruder.
M119 reports all switches as open and triggered when pressed.

PSU problem?

Any idea as to what the problem is?

when you turn on power,could the psu power up the main board.please check the lights of fuse and send me the picture of mianboard when powering up.

There are no lights on the board until the USB is plugged in.
LED on the board will flash a few time when pressing the connect button in Repetier.
There are no lights on the PSU, should there be?

please check the psu.the output woltage is 12V.
when powering up,the led marked by the red circlie would be light up .
