Mac Pro no signal anymore
I was watching a YouTube video when all of a sudden the computer shut down. Then I turned it back on and everything seemed normal, but suddenly the image disappeared: a black screen. Since then I can't get an image. I thought it was the graphics card, so I got another identical one, but that didn't help.
I ran the tests.
OVTMP CPU A -> ok
OVTMP CPU B -> ok
No RAM diode problem...
When I press the diagnostic button, the 5V diode lights up when the computer is switched off. When I press it again and start the computer, the following LEDs light up:
But the SYS.PG LED doesn't!
Do you have any idea what's wrong? Could it be the power supply?
I plug my iPhone in usb and it’s not charging , keyboard no light. I heard the hdd start and all the fans are ok.
