Fujitsu TV has no power?

Fujitsu 50 wide plasma model # P50XHA30WS. The TV doesnt turn on at all, no picture, no sound, no color blinking,nothing. I open the TV and I use my tester to see if power was going to the power supply and that seems to be fine, The cable going to the power supply have power but the problem still the same,any advice would help, thanks
