It doesn't do anything when you press the power button?

I would start by unplugging the X and Y mains, one at a time, to see if it will power on. Make sure you unplug them with the set off and the PSU caps discharged. Leave the set unplugged for at least 10 minutes before you plug the board(s) back in.

This is the LG made Plasma for visio, I had one replaced all the caps in the PS and had proper voltage for VA/VS and I couldn't get it to show a picture.

I replaced 9x 3300uf 35v caps and x1 1000uf 25v cap.

The LG made Vizio is a pain. I would look for small cracks on the very edge of the panel.

Photos will help too.

Have you done ANY diagnosis or do you expect someone to guess? You need to tell us what you have checked. 5V standby is good? Any main rails when you press power button? Are all fuses on the main board OK? All regulators OK? Did you check the power button works by seeing if the main board receives an ON/OFF signal (check the pins on the button connector for voltage change as you press buttons.)

Pictures of the chassis?
