I can see the Diagnostic Leds, and
Number 1 : It's On when connect the AC Cable
When I push the start button the Leds 2 and 3 turn ON
No 2: ON
No 3: ON
But the LED 4 do not. Still OFF. And the Fans not working, some advice about it?
The SMC was reset and nothing happens.

LED #4
Indicates that the computer and the LCD display panel are communicating. This LED will be ON when the computer is turned on and video signal is being generated. If the LED is ON and there is no image on the LCD display panel, the LCD display panel or inverter might be installed incorrectly or need replacement.
