Hello
I am electronic engineer and I have for service 2 alien 220w who doesnt power on.
No boot logo on lcd no pc communication.
I have disassembly the mod I measure the components diode , transistor, mosfet and all looks ok
In power supply with 7 volt I see that if I press the power button ,it draws about 70 ma for about 3 second and then stop.
Have any one have the same problem ?
I believe that maybe is the crystal from micro controller and for this reason can not run the program and boot
Also does any one know were I can find spare part like pcb or lcd for this unit?
Thanks
