Hello community I tell you first of all that the problem is not the CPU, since it is walking with another monitor. This particular monitor turns on and says it verifies the connections and everything, but when I connect the VGA cable directly, an energy-saving mode poster comes out and the screen turns off. (Let's say it goes into standby as when your computer is branded or something like that the source is still running but the image of the PC is black) My doubt is it has a solution. check the source of the monitor, the contacts of the board, everything is ok. no undervalued capacitor or false contacts. I don't know what to do anymore and it's a shame because the monitor works: / of course thanks to everyone. And regards.

Hi. Did you solve the problem? The same happens to me. They say that it is an eeprom problem.
