My A20T is dead!

[fwhite]

Looking to gain advice for testing a dead machine with these symotoms:
Switch light works. No motors are on. Screen is blank. Light on mother board is lit.
Can someone with more knowledge than me help? Frank

Hello, can you use USB to connect to a computer for control? There may be a problem with your LCD screen. If your motor does not move, try to swap the drivers on the motherboard to see if it can work normally. If you have any questions, you can go to the place shown in the figure and ask for help from geeetech's technical staff.
