Mac Pro turns on no screen no light on keyboard
Hi all
i got issue with Mac Pro 4.1 upgraded to 5.1 , 2 x 3.33ghz 96g ram gtx285
problem is Mac turns on fan spin I can hear hard start spinning, graphic card fans spin But nothing on screen and No light on keyboard
problems started after I tried to clean the keyboard and Mac was off but keyboard was connected to front panel
I changed front panel , I changed power supply
When I press Diag all led on motherboard is green except 5V STBY which is yellow
I don’t know what else to do
I have tried to reset power management on motherboard as I don’t get any light on keyboard
I have done most thing on user manual, again I have changed PSU
I have clean and brushed motherboard to make sure nothing extra on board
