Sony KDL-46VE5 Bravia -- no picture, no backlight, standyby light goes from red to green Can't Post

Standby light is red while plugged in, goes green when turned on, and I can hear the relay click.

But no picture, no backlight in the dark, and a flashlight shined at the screen in the dark shows no image.

Unsure if there's audio.

Usually TV stays on, but sometimes after turning on, will cycle from green on, to standby red.

Have checked voltages on the following:

While TV On:

Back Light On = 0.45v

Heater On = 3.3v

H Sync = 0

Dimmer = 1.46v

Inv Err = 0.40v

TV Off

All above 0v
