Hello, got this 3437 that has a 3 time fan spin but no display. When I do a pram reset display flashes and reboots normally. Backlight is turning on it has 24v but no image appearing. Any suggestions?

I have USB activity on USB Mouse. No external display. I do have a chime. Will try another display now that works for sure.

Working display is the same, Apple logo turns on but no image after chime. I also tried to boot from external drive, same.

problem solved, i just had a customer coming in with the same issue. His harddrive was fried, some black IC, shorting the 3.3v line i guess. Removed the drive and worked. I took the drive out of this one, works as well
