Hi,
After a problem psu, you send a new electric power. But LCD is down. Only lights up when i connect I3 to my laptop, LCD works. but no drivers finding.
And X Y Z don't move. Help !

Have you re-attached the square power plug from the PSU to the board?
If you don't then the board will only power from USB and wont run the stepper motors.

Have you tried to check the voltage like the picture shows below?

[Gingko]

It should be 3.8V-5V.

[regisregis]

I can't, no tool for this.

And now? i ask a new card?

[Gingko]

If it's not 3.8V-5V, then it might be the mainboard problem.

Hi, i bought a voltmeter and i tested the mainboard.
No measure, volt : 0.00

i bought your product by amazon...
