Default Viewsonic N3752W, turns on green light, but no screen..

So, starting yesterday turning on my Viewsonic N3752W lcd tv the red standby light turns to green but the screen never comes on, no blink, nothing but blackness doesn't even try to turn on. But the light stays solid green, until turned off again and it returns to red although the screen stays off the entire time.

Ideas on what to check first?

Do you get sound? If so, it is probably an inverter problem.

Nope, no sound. Nothing, just the lights stays solid green but nothing.. black screen, no sound, not even backlight.

That suggests a main board problem.
