Samsung UN32F5500AFXZA turning off after 1 minute or so

[aaron_mciver]

This TV is on 24/7 as it is mainly used to display photos within the house. Recently however we turned it off and now turning it back on leads to it turning itself off within a 1 minute or so.

I have verified that no timers are shutting the TV off. I did remove the back panel to see if anything looked suspicious however I noted nothing.

Is anyone familiar with might be the issue? Any simple steps I can take to identify the issue? When on, it's operating as it always did and looks great!

measure the pins on the PSU connector where the cables go from it to the main board with a DMM. Write down the pin out name with the voltages you have measured with the tv on and then after it turns itself off. The ground lead to chassis GND or the GND pin on the connector.
