Computer starts, without video.

The cabinet starts, the strangest thing is that there is no screen, no image.

Try these sequence. clean fan, cooler, verify that the hard drive boots, replaced memories, replaced cmos battery, clean all peripherals, change vga cable, probe with another monitor, source replaced, clean processor, change jumpers position, panel cables placed on the correct place,

The motherboar is foxcon n15235.

Please suggestions. Thank you

What does the LED light on your monitor do? Does it stay in Standby mode (amber light) or does it go green light? Do you see the BIOS splash screen being displayed?

thanks for answering iko,

Absolutely nothing of movements on the screen, everything seems to work less the screen and as I said in my initial post I tried several possible solutions.

Yes, I mention it estimated, I tested it on 2 functional monitors. @Ranger4
