No display power lite is green

This is probably pulling too much power from the power source.

possible that the flex holding the lcd is broken.

Hello,
Check your fans o see if they are running and if the PC isn't getting too hot because that will cause it to stop and not boot up.

The power green light is the power to the unit. I believe that you have a motherboard issue, sorry to say.

Acer's repair site is as follows

When you switch the monitors, do you still use the very same vga cable? If you don't, then it's time to change the monitor. When it turns on and off inmediately it means that it's receiving the signal, but that's it. If it's brand new, exchange it.

sometimes are dried capacitors and sometimes are ic transistor near the inversors

This can sometimes be caused by the single smt capacitor on the board in the top half that the screen cables plug in to. Try replacing the cap or the entire board.
