Sanyo DP26640

Hi, this TV when turned on the green light comes on then after a second goes back off.
No picture, no back light, no sound. Dead

I can't see any bad caps so I checked the voltage on the only 2 regulators it has.
They are both 1117S then have ADJ 014 beneath the 1117s..

Stub north, pins left to right.

1st;
pin 1 7.83
pin 2 9.09
pin 3 12.20

2nd;
pin 1 0.04
pin 2 0.07
pin 3 0.07

Any help would be appreciated.

Thanks.

What DCV do you get on those pins when TV is OFF and when power switch is activated?
"2nd;
pin 1 0.04
pin 2 0.07
pin 3 0.07"
No input = No output which can be due to the Input is fed from switched power supply section when PS-ON is applied to the power supply board.
We also need the pictures of the whole back side of the TV so we can see how all the board are connected.
