Sony Bravia KDL-55EX710

Picked up a Sony Bravia KDL-55EX710. Has 7 blinks. Once in a great while will start. Normally it just clicks on the right back off. Has energy saving swith on the side instead of in the settings like normal. Standby is 1.5 instead of 3.3. Any sugestions?

Start by providing good clear pictures of the whole backside of the TV showing all the boards, and then good clear pictures of the connectors of the power supply board so we read pin names.
How about other Voltage readings?

Training manual for similar model here. Says 7 blinks is temperature (main board).

I freeze sprayed the main board, and it would turn on, but only for a couple seconds

The only voltage i can check on the PS is the standby, because it will not turn on. I have 1.5 at the 3.3.

If you truly has only 1.5V to run the main board, I doubt that it will be enough for the main board to run and produce 7-blink code. Meter is good for sure?
So all other pins on that power supply's connector that goes to the main board show what Voltages? 0 Volt?
