Preen fm2 Issue

[devthhtous]

 I have a preenfm2 which was perfectly functioning until this morning. I connect it to my computer through a usb cable and after it turns on (I can see all the yellow squares filling the screen), it turns off immediately. Do you know what might be wrong?

Hello,

Where did you get the Preen? Built yourself?

Various reasons:
1) Can you power it from Adaptor? maybe there is not enough current coming from your computer. It needs around 500mA to operate.
2) Something has come loose inside. The controller and screen are with connectors.
3) Other possible issues.
