SONY PCV-RZ32G display problems

[GEOrifle]

Hi guys.
I have this PC several years and ones i turned on , everything works but i have no dispaly image on screen, display is still in sleep mode.
So i dissconected everything, cleaned up, put back all together but still no results.
Removed MOB from the case, changed several PSU, memorys, CMOS battery, Video cards, even CPU but i still have no image.
MOB is OEM by ASUS P4SD-VX with high quality CAP's, working all fans, PSU, CPU fan, HDD is running, CD-DVD's also.
Can someone give me clue what shoud be wrong?

Have you tried a different screen? Since you've tried everythig else it seams you have a dead monitor or a bad monitor cable.
