No picture, just green light
When I turn on my 40 inch Sony Bravia, the tv clicks and the green light comes on. I don’t have any picture or sound. I’ve been told to shine a light in the dark to see if I can see the picture. I tried it and light just reflects off screen. I can’t see any picture. Any suggestions? Could it still be the inverter board? It was working fine, then one day no picture. No warning signs before it happened.

Here is a picture of the whole back and each board. It is model KDL-40S504. I have a multimeter as well.
I tried to see if it was in standby mode. It didn’t work when putting in the combo with the remote. Here is a picture of the T-Con board.
